+# Kafka
+
+[Kafka](https://kafka.apache.org/) is a distributed streaming platform used for building real-time data pipelines and streaming apps. It is horizontally scalable, fault-tolerant, wicked fast, and runs in production in thousands of companies.
+
+## TL;DR
+
+```console
+helm repo add bitnami https://charts.bitnami.com/bitnami
+helm install my-release bitnami/kafka
+```
+
+## Introduction
+
+This chart bootstraps a [Kafka](https://github.com/bitnami/bitnami-docker-kafka) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.
+
+## Prerequisites
+
+- Kubernetes 1.12+
+- Helm 3.1.0
+- PV provisioner support in the underlying infrastructure
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm repo add bitnami https://charts.bitnami.com/bitnami
+helm install my-release bitnami/kafka
+```
+
+These commands deploy Kafka on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Parameters
+
+The following tables lists the configurable parameters of the Kafka chart and their default values per section/component:

+### Zookeeper chart parameters
+
+| Parameter                       | Description                                          | Default |

+| `zookeeper.persistence.enabled` | Enable Zookeeper persistence using PVC               | `true`  |
+| `externalZookeeper.servers`     | Server or list of external Zookeeper servers to use  | `[]`    |
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+helm install my-release \
+  --set replicaCount=3 \
+  bitnami/kafka
+```
+
+The above command deploys Kafka with 3 brokers (replicas).
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```console
+helm install my-release -f values.yaml bitnami/kafka
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Configuration and installation details
+
+### [Rolling VS Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
+
+It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
+
+Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
+
+### Setting custom parameters
+
+Any environment variable beginning with `KAFKA_CFG_` will be mapped to its corresponding Kafka key. For example, use `KAFKA_CFG_BACKGROUND_THREADS` in order to set `background.threads`. In order to pass custom environment variables use the `extraEnvVars` property.
+
+Using `extraEnvVars` with `KAFKA_CFG_` is the preferred and simplest way to add custom Kafka parameters not otherwise specified in this chart. Alternatively, you can provide a *full* Kafka configuration using `config` or `existingConfigmap`.
+Setting either `config` or `existingConfigmap` will cause the chart to disregard `KAFKA_CFG_` settings, which are used by many other Kafka-related chart values described above, as well as dynamically generated parameters such as `zookeeper.connect`. This can cause unexpected behavior.
+
+### Listeners configuration
+
+This chart allows you to automatically configure Kafka with 3 listeners:
+
+- One for inter-broker communications.
+- A second one for communications with clients within the K8s cluster.
+- (optional) a third listener for communications with clients outside the K8s cluster. Check [this section](#accessing-kafka-brokers-from-outside-the-clusters) for more information.
+
+For more complex configurations, set the `listeners`, `advertisedListeners` and `listenerSecurityProtocolMap` parameters as needed.
+
+### Enable security for Kafka and Zookeeper
+
+You can configure different authentication protocols for each listener you configure in Kafka. For instance, you can use `sasl_tls` authentication for client communications, while using `tls` for inter-broker communications. This table shows the available protocols and the security they provide:
+
+| Method    | Authentication               | Encryption via TLS |
+|-----------|------------------------------|--------------------|
+| plaintext | None                         | No                 |
+| tls       | None                         | Yes                |
+| mtls      | Yes (two-way authentication) | Yes                |
+| sasl      | Yes (via SASL)               | No                 |
+| sasl_tls  | Yes (via SASL)               | Yes                |
+
+Learn more about how to configure Kafka to use the different authentication protocols in the [chart documentation](https://docs.bitnami.com/kubernetes/infrastructure/kafka/administration/enable-security/).
+
+If you enabled SASL authentication on any listener, you can set the SASL credentials using the parameters below:
+
+- `auth.sasl.jaas.clientUsers`/`auth.sasl.jaas.clientPasswords`: when enabling SASL authentication for communications with clients.
+- `auth.sasl.jaas.interBrokerUser`/`auth.sasl.jaas.interBrokerPassword`:  when enabling SASL authentication for inter-broker communications.
+- `auth.jaas.zookeeperUser`/`auth.jaas.zookeeperPassword`: In the case that the Zookeeper chart is deployed with SASL authentication enabled.
+
+In order to configure TLS authentication/encryption, you **can** create a secret containing the Java Key Stores (JKS) files: the truststore (`kafka.truststore.jks`) and one keystore (`kafka.keystore.jks`) per Kafka broker you have in the cluster. Then, you need pass the secret name with the `--auth.jksSecret` parameter when deploying the chart.
+
+> **Note**: If the JKS files are password protected (recommended), you will need to provide the password to get access to the keystores. To do so, use the `auth.jksPassword` parameter to provide your password.
+
+For instance, to configure TLS authentication on a Kafka cluster with 2 Kafka brokers use the command below to create the secret:
+
+```console
+kubectl create secret generic kafka-jks --from-file=./kafka.truststore.jks --from-file=./kafka-0.keystore.jks --from-file=./kafka-1.keystore.jks
+```
+
+> **Note**: the command above assumes you already created the trustore and keystores files. This [script](https://raw.githubusercontent.com/confluentinc/confluent-platform-security-tools/master/kafka-generate-ssl.sh) can help you with the JKS files generation.
+
+As an alternative to manually create the secret before installing the chart, you can put your JKS files inside the chart folder `files/jks`, an a secret including them will be generated. Please note this alternative requires to have the chart downloaded locally, so you will have to clone this repository or fetch the chart before installing it.
+
+If, for some reason (like using Cert-Manager) you can not use the default JKS secret scheme, you can use the additional parameters:
+
+- `auth.jksTruststoreSecret` to define additional secret, where the `kafka.truststore.jks` is being kept. The truststore password **must** be the same as in `auth.jksPassword`
+- `auth.jksTruststore` to overwrite the default value of the truststore key (`kafka.truststore.jks`).
+- `auth.jksKeystoreSAN` if you want to use a SAN certificate for your brokers. Setting this parameter would mean that the chart expects a existing key in the `auth.jksSecret` with the `auth.jksKeystoreSAN`-value and use this as a keystore for **all** brokers
+
+> **Note**: The truststore/keystore from above **must** be protected with the same password as in `auth.jksPassword`
+
+You can deploy the chart with authentication using the following parameters:
+
+```console
+replicaCount=2
+auth.clientProtocol=sasl
+auth.interBrokerProtocol=tls
+auth.certificatesSecret=kafka-jks
+auth.certificatesPassword=jksPassword
+auth.sasl.jaas.clientUsers[0]=brokerUser
+auth.sasl.jaas.clientPasswords[0]=brokerPassword
+auth.jaas.zookeeperUser=zookeeperUser
+auth.jaas.zookeeperPassword=zookeeperPassword
+zookeeper.auth.enabled=true
+zookeeper.auth.serverUsers=zookeeperUser
+zookeeper.auth.serverPasswords=zookeeperPassword
+zookeeper.auth.clientUser=zookeeperUser
+zookeeper.auth.clientPassword=zookeeperPassword
+```
+
+If you also enable exposing metrics using the Kafka expoter, and you are using `sasl_tls`, `tls`, or `mtls` authentication protocols, you need to mount the CA certificated used to sign the brokers certificates in the exporter so it can validate the Kafka brokers. To do so, create a secret containing the CA, and set the `metrics.certificatesSecret` parameter. As an alternative, you can skip TLS validation using extra flags:
+
+```console
+metrics.kafka.extraFlags={tls.insecure-skip-tls-verify: ""}
+```
+
+### Accessing Kafka brokers from outside the cluster
+
+In order to access Kafka Brokers from outside the cluster, an additional listener and advertised listener must be configured. Additionally, a specific service per kafka pod will be created.
+
+There are two ways of configuring external access. Using LoadBalancer services or using NodePort services.
+
+#### Using LoadBalancer services
+
+You have two alternatives to use LoadBalancer services:
+
+- Option A) Use random load balancer IPs using an **initContainer** that waits for the IPs to be ready and discover them automatically.
+
+```console
+externalAccess.enabled=true
+externalAccess.service.type=LoadBalancer
+externalAccess.service.port=9094
+externalAccess.autoDiscovery.enabled=true
+serviceAccount.create=true
+rbac.create=true
+```
+
+Note: This option requires creating RBAC rules on clusters where RBAC policies are enabled.
+
+- Option B) Manually specify the load balancer IPs:
+
+```console
+externalAccess.enabled=true
+externalAccess.service.type=LoadBalancer
+externalAccess.service.port=9094
+externalAccess.service.loadBalancerIPs[0]='external-ip-1'
+externalAccess.service.loadBalancerIPs[1]='external-ip-2'}
+```
+
+Note: You need to know in advance the load balancer IPs so each Kafka broker advertised listener is configured with it.
+
+#### Using NodePort services
+
+You have two alternatives to use NodePort services:
+
+- Option A) Use random node ports using an **initContainer** that discover them automatically.
+
+```console
+externalAccess.enabled=true
+externalAccess.service.type=NodePort
+externalAccess.autoDiscovery.enabled=true
+serviceAccount.create=true
+rbac.create=true
+```
+
+Note: This option requires creating RBAC rules on clusters where RBAC policies are enabled.
+
+- Option B) Manually specify the node ports:
+
+```console
+externalAccess.enabled=true
+externalAccess.service.type=NodePort
+externalAccess.service.nodePorts[0]='node-port-1'
+externalAccess.service.nodePorts[1]='node-port-2'
+```
+
+Note: You need to know in advance the node ports that will be exposed so each Kafka broker advertised listener is configured with it.
+
+The pod will try to get the external ip of the node using `curl -s https://ipinfo.io/ip` unless `externalAccess.service.domain` or `externalAccess.service.useHostIPs` is provided.
+
+Following the aforementioned steps will also allow to connect the brokers from the outside using the cluster's default service (when `service.type` is `LoadBalancer` or `NodePort`). Use the property `service.externalPort` to specify the port used for external connections.
+
+#### Name resolution with External-DNS
+
+You can use the following values to generate External-DNS annotations which automatically creates DNS records for each ReplicaSet pod:
+
+```yaml
+externalAccess:
+  service:
+    annotations:
+      external-dns.alpha.kubernetes.io/hostname: "{{ .targetPod }}.example.com"
+```
+### Sidecars
+
+If you have a need for additional containers to run within the same pod as Kafka (e.g. an additional metrics or logging exporter), you can do so via the `sidecars` config parameter. Simply define your container according to the Kubernetes container spec.
+
+```yaml
+sidecars:
+  - name: your-image-name
+    image: your-image
+    imagePullPolicy: Always
+    ports:
+      - name: portname
+       containerPort: 1234
+```
+
+### Setting Pod's affinity
+
+This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod's affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
+
+As an alternative, you can use of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.
+
+### Deploying extra resources
+
+There are cases where you may want to deploy extra objects, such as Kafka Connect. For covering this case, the chart allows adding the full specification of other objects using the `extraDeploy` parameter. The following example would create a deployment including a Kafka Connect deployment so you can connect Kafka with MongoDB®:
+
+```yaml
+## Extra objects to deploy (value evaluated as a template)
+##
+extraDeploy:
+  - |
+    apiVersion: apps/v1
+    kind: Deployment
+    metadata:
+      name: {{ include "kafka.fullname" . }}-connect
+      labels: {{- include "common.labels.standard" . | nindent 4 }}
+        app.kubernetes.io/component: connector
+    spec:
+      replicas: 1
+      selector:
+        matchLabels: {{- include "common.labels.matchLabels" . | nindent 6 }}
+          app.kubernetes.io/component: connector
+      template:
+        metadata:
+          labels: {{- include "common.labels.standard" . | nindent 8 }}
+            app.kubernetes.io/component: connector
+        spec:
+          containers:
+            - name: connect
+              image: KAFKA-CONNECT-IMAGE
+              imagePullPolicy: IfNotPresent
+              ports:
+                - name: connector
+                  containerPort: 8083
+              volumeMounts:
+                - name: configuration
+                  mountPath: /bitnami/kafka/config
+          volumes:
+            - name: configuration
+              configMap:
+                name: {{ include "kafka.fullname" . }}-connect
+  - |
+    apiVersion: v1
+    kind: ConfigMap
+    metadata:
+      name: {{ include "kafka.fullname" . }}-connect
+      labels: {{- include "common.labels.standard" . | nindent 4 }}
+        app.kubernetes.io/component: connector
+    data:
+      connect-standalone.properties: |-
+        bootstrap.servers = {{ include "kafka.fullname" . }}-0.{{ include "kafka.fullname" . }}-headless.{{ .Release.Namespace }}.svc.{{ .Values.clusterDomain }}:{{ .Values.service.port }}
+        ...
+      mongodb.properties: |-
+        connection.uri=mongodb://root:password@mongodb-hostname:27017
+        ...
+  - |
+    apiVersion: v1
+    kind: Service
+    metadata:
+      name: {{ include "kafka.fullname" . }}-connect
+      labels: {{- include "common.labels.standard" . | nindent 4 }}
+        app.kubernetes.io/component: connector
+    spec:
+      ports:
+        - protocol: TCP
+          port: 8083
+          targetPort: connector
+      selector: {{- include "common.labels.matchLabels" . | nindent 4 }}
+        app.kubernetes.io/component: connector
+```
+
+You can create the Kafka Connect image using the Dockerfile below:
+
+```Dockerfile
+FROM bitnami/kafka:latest
+# Download MongoDB® Connector for Apache Kafka https://www.confluent.io/hub/mongodb/kafka-connect-mongodb
+RUN mkdir -p /opt/bitnami/kafka/plugins && \
+    cd /opt/bitnami/kafka/plugins && \
+    curl --remote-name --location --silent https://search.maven.org/remotecontent?filepath=org/mongodb/kafka/mongo-kafka-connect/1.2.0/mongo-kafka-connect-1.2.0-all.jar
+CMD /opt/bitnami/kafka/bin/connect-standalone.sh /opt/bitnami/kafka/config/connect-standalone.properties /opt/bitnami/kafka/config/mongo.properties
+```
+
+## Persistence
+
+The [Bitnami Kafka](https://github.com/bitnami/bitnami-docker-kafka) image stores the Kafka data at the `/bitnami/kafka` path of the container.
+
+Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the [Parameters](#persistence-parameters) section to configure the PVC or to disable persistence.
+
+### Adjust permissions of persistent volume mountpoint
+
+As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
+
+By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
+As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
+
+You can enable this initContainer by setting `volumePermissions.enabled` to `true`.

+Find more information about how to deal with common errors related to Bitnami’s Helm charts in [this troubleshooting guide](https://docs.bitnami.com/general/how-to/troubleshoot-helm-chart-issues).
+
+## Upgrading
+
+### To 12.2.0
+
+This version also introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/master/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
+
+### To 12.0.0
+
+[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
+
+**What changes were introduced in this major version?**
+
+- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
+- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
+- After running `helm dependency update`, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
+- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
+
+**Considerations when upgrading to this version**
+
+- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
+- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
+- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
+
+**Useful links**

+
+### To 11.8.0
+
+External access to brokers can now be achieved through the cluster's Kafka service.
+
+- `service.nodePort` -> deprecated  in favor of `service.nodePorts.client` and `service.nodePorts.external`
+
+### 11.7.0
+
+The way to configure the users and passwords changed. Now it is allowed to create multiple users during the installation by providing the list of users and passwords.
+
+- `auth.jaas.clientUser` (string) -> deprecated  in favor of `auth.jaas.clientUsers` (array).
+- `auth.jaas.clientPassword` (string) -> deprecated  in favor of `auth.jaas.clientPasswords` (array).
+
+### 11.0.0
+
+The way to configure listeners and athentication on Kafka is totally refactored allowing users to configure different authentication protocols on different listeners. Please check the sections [Listeners Configuration](listeners-configuration) and [Listeners Configuration](enable-kafka-for-kafka-and-zookeeper) for more information.
+
+Backwards compatibility is not guaranteed you adapt your values.yaml to the new format. Here you can find some parameters that were renamed or disappeared in favor of new ones on this major version:
+
+- `auth.enabled` -> deprecated in favor of `auth.clientProtocol` and `auth.interBrokerProtocol` parameters.
+- `auth.ssl` -> deprecated in favor of `auth.clientProtocol` and `auth.interBrokerProtocol` parameters.
+- `auth.certificatesSecret` -> renamed to `auth.jksSecret`.
+- `auth.certificatesPassword` -> renamed to `auth.jksPassword`.
+- `sslEndpointIdentificationAlgorithm` -> renamedo to `auth.tlsEndpointIdentificationAlgorithm`.
+- `auth.interBrokerUser` -> renamed to `auth.jaas.interBrokerUser`
+- `auth.interBrokerPassword` -> renamed to `auth.jaas.interBrokerPassword`
+- `auth.zookeeperUser` -> renamed to `auth.jaas.zookeeperUser`
+- `auth.zookeeperPassword` -> renamed to `auth.jaas.zookeeperPassword`
+- `auth.existingSecret` -> renamed to `auth.jaas.existingSecret`
+- `service.sslPort` -> deprecated in favor of `service.internalPort`
+- `service.nodePorts.kafka` and `service.nodePorts.ssl` -> deprecated in favor of `service.nodePort`
+- `metrics.kafka.extraFlag` -> new parameter
+- `metrics.kafka.certificatesSecret` -> new parameter
+
+### 10.0.0
+
+If you are setting the `config` or `log4j` parameter, backwards compatibility is not guaranteed, because the `KAFKA_MOUNTED_CONFDIR` has moved from `/opt/bitnami/kafka/conf` to `/bitnami/kafka/config`. In order to continue using these parameters, you must also upgrade your image to `docker.io/bitnami/kafka:2.4.1-debian-10-r38` or later.
+
+### 9.0.0
+
+Backwards compatibility is not guaranteed you adapt your values.yaml to the new format. Here you can find some parameters that were renamed on this major version:
+
+```diff
+- securityContext.enabled
+- securityContext.fsGroup
+- securityContext.fsGroup
++ podSecurityContext
+- externalAccess.service.loadBalancerIP
++ externalAccess.service.loadBalancerIPs
+- externalAccess.service.nodePort

+Ports names were prefixed with the protocol to comply with Istio (see https://istio.io/docs/ops/deployment/requirements/).
+
+### 8.0.0
+
+There is not backwards compatibility since the brokerID changes to the POD_NAME. For more information see [this PR](https://github.com/bitnami/charts/pull/2028).
+
+### 7.0.0
+
+Backwards compatibility is not guaranteed when Kafka metrics are enabled, unless you modify the labels used on the exporter deployments.
+Use the workaround below to upgrade from versions previous to 7.0.0. The following example assumes that the release name is kafka:
+
+```console
+helm upgrade kafka bitnami/kafka --version 6.1.8 --set metrics.kafka.enabled=false
+helm upgrade kafka bitnami/kafka --version 7.0.0 --set metrics.kafka.enabled=true
+```
+
+### 2.0.0
+
+Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
+Use the workaround below to upgrade from versions previous to 2.0.0. The following example assumes that the release name is kafka:
+
+```console
+kubectl delete statefulset kafka-kafka --cascade=false
+kubectl delete statefulset kafka-zookeeper --cascade=false
+```
+
+### 1.0.0
+
+Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
+Use the workaround below to upgrade from versions previous to 1.0.0. The following example assumes that the release name is kafka:
+
+```console
+kubectl delete statefulset kafka-kafka --cascade=false
+kubectl delete statefulset kafka-zookeeper --cascade=false
+```

+
+A [Helm Library Chart](https://helm.sh/docs/topics/library_charts/#helm) for grouping common logic between bitnami charts.
+
+## TL;DR
+
+```yaml
+dependencies:
+  - name: common
+    version: 0.x.x
+    repository: https://charts.bitnami.com/bitnami
+```
+
+```bash
+$ helm dependency update

+
+## Introduction
+
+This chart provides a common template helpers which can be used to develop new charts using [Helm](https://helm.sh) package manager.
+
+Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.

+
+#### Example of use
+
+When we store sensitive data for a deployment in a secret, some times we want to give to users the possibility of using theirs existing secrets.
+
+```yaml
+# templates/secret.yaml
+---
+apiVersion: v1
+kind: Secret
+metadata:
+  name: {{ include "common.names.fullname" . }}
+  labels:
+    app: {{ include "common.names.fullname" . }}
+type: Opaque
+data:
+  password: {{ .Values.password | b64enc | quote }}
+
+# templates/dpl.yaml
+---
+...
+      env:
+        - name: PASSWORD
+          valueFrom:
+            secretKeyRef:
+              name: {{ include "common.secrets.name" (dict "existingSecret" .Values.existingSecret "context" $) }}
+              key: {{ include "common.secrets.key" (dict "existingSecret" .Values.existingSecret "key" "password") }}
+...
+
+# values.yaml
+---
+name: mySecret
+keyMapping:
+  password: myPasswordKey
+```
+
+### ValidateValue
+
+#### NOTES.txt
+
+```console
+{{- $validateValueConf00 := (dict "valueKey" "path.to.value00" "secret" "secretName" "field" "password-00") -}}
+{{- $validateValueConf01 := (dict "valueKey" "path.to.value01" "secret" "secretName" "field" "password-01") -}}
+
+{{ include "common.validations.values.multiple.empty" (dict "required" (list $validateValueConf00 $validateValueConf01) "context" $) }}
+```
+
+If we force those values to be empty we will see some alerts
+
+```console
+$ helm install test mychart --set path.to.value00="",path.to.value01=""
+    'path.to.value00' must not be empty, please add '--set path.to.value00=$PASSWORD_00' to the command. To get the current value:
+
+        export PASSWORD_00=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-00}" | base64 --decode)
+
+    'path.to.value01' must not be empty, please add '--set path.to.value01=$PASSWORD_01' to the command. To get the current value:
+
+        export PASSWORD_01=$(kubectl get secret --namespace default secretName -o jsonpath="{.data.password-01}" | base64 --decode)
+```
+
+## Upgrading
+
+### To 1.0.0
+
+[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
+
+**What changes were introduced in this major version?**
+
+- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
+- Use `type: library`. [Here](https://v3.helm.sh/docs/faq/#library-chart-support) you can find more information.
+- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
+
+**Considerations when upgrading to this version**
+
+- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
+- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
+- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
+
+**Useful links**

+# ZooKeeper
+
+[ZooKeeper](https://zookeeper.apache.org/) is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or other by distributed applications.
+
+## TL;DR
+
+```console
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm install my-release bitnami/zookeeper
+```
+
+## Introduction
+
+This chart bootstraps a [ZooKeeper](https://github.com/bitnami/bitnami-docker-zookeeper) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.
+
+## Prerequisites
+
+- Kubernetes 1.12+
+- Helm 3.1.0
+- PV provisioner support in the underlying infrastructure
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm install my-release bitnami/zookeeper
+```
+
+These commands deploy ZooKeeper on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+$ helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Parameters

+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```console
+$ helm install my-release \
+  --set auth.clientUser=newUser \
+    bitnami/zookeeper
+```
+
+The above command sets the ZooKeeper user to `newUser`.
+
+> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```console
+$ helm install my-release -f values.yaml bitnami/zookeeper
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Configuration and installation details
+
+### [Rolling vs Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
+
+It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
+
+Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
+
+### Configure log level
+
+You can configure the ZooKeeper log level using the `ZOO_LOG_LEVEL` environment variable. By default, it is set to `ERROR` because of each readiness probe produce an `INFO` message on connection and a `WARN` message on disconnection.
+
+## Persistence
+
+The [Bitnami ZooKeeper](https://github.com/bitnami/bitnami-docker-zookeeper) image stores the ZooKeeper data and configurations at the `/bitnami/zookeeper` path of the container.
+
+Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the [Parameters](#parameters) section to configure the PVC or to disable persistence.
+
+If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).
+
+### Adjust permissions of persistent volume mountpoint
+
+As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
+
+By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
+As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
+
+You can enable this initContainer by setting `volumePermissions.enabled` to `true`.
+
+### Configure the data log directory
+
+You can use a dedicated device for logs (instead of using the data directory) to help avoiding competition between logging and snaphots. To do so, set the `dataLogDir` parameter with the path to be used for writing transaction logs. Alternatively, set this parameter with an empty string and it will result in the log being written to the data directory (Zookeeper's default behavior).
+
+When using a dedicated device for logs, you can use a PVC to persist the logs. To do so, set `persistence.enabled` to `true`. See the [Persistence Parameters](#persistence-parameters) section for more information.
+
+### Set pod affinity
+
+This chart allows you to set custom pod affinity using the `affinity` parameter. Find more information about pod affinity in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
+
+As an alternative, you can use any of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

+
+## Upgrading
+
+### 6.1.0
+
+This version introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/master/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
+
+### To 6.0.0
+
+[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
+
+[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/infrastructure/zookeeper/administration/upgrade-helm3/).
+
+### To 5.21.0
+
+A couple of parameters related to Zookeeper metrics were renamed or disappeared in favor of new ones:
+
+- `metrics.port` is renamed to `metrics.containerPort`.
+- `metrics.annotations` is deprecated in favor of `metrics.service.annotations`.
+
+### To 3.0.0
+
+This new version of the chart includes the new ZooKeeper major version 3.5.5. Note that to perform an automatic upgrade
+of the application, each node will need to have at least one snapshot file created in the data directory. If not, the
+new version of the application won't be able to start the service. Please refer to [ZOOKEEPER-3056](https://issues.apache.org/jira/browse/ZOOKEEPER-3056)
+in order to find ways to workaround this issue in case you are facing it.
+
+### To 2.0.0
+
+Backwards compatibility is not guaranteed unless you modify the labels used on the chart's statefulsets.
+Use the workaround below to upgrade from versions previous to 2.0.0. The following example assumes that the release name is `zookeeper`:
+
+```console
+$ kubectl delete statefulset zookeeper-zookeeper --cascade=false
+```
+
+### To 1.0.0
+
+Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
+Use the workaround below to upgrade from versions previous to 1.0.0. The following example assumes that the release name is zookeeper:
+
+```console
+$ kubectl delete statefulset zookeeper-zookeeper --cascade=false
+```

+When we store sensitive data for a deployment in a secret, some times we want to give to users the possibility of using theirs existing secrets.
+
+```yaml

+
+## Upgrading
+
+### To 1.0.0
+
+[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
+
+**What changes were introduced in this major version?**
+
+- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
+- Use `type: library`. [Here](https://v3.helm.sh/docs/faq/#library-chart-support) you can find more information.
+- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
+
+**Considerations when upgrading to this version**
+
+- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
+- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
+- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
+

+Find more info in [this section](https://github.com/bitnami/charts/tree/master/bitnami/kafka#enable-security-for-kafka-and-zookeeper) of the README.md file.
+
+## Java Key Stores
+
+You can copy here your Java Key Stores (JKS) files so a secret is created including them. Remember to use a truststore (`kafka.truststore.jks`) and one keystore (`kafka.keystore.jks`) per Kafka broker you have in the cluster. For instance, if you have 3 brokers you need to copy here the following files:
+
+- kafka.truststore.jks
+- kafka-0.keystore.jks
+- kafka-1.keystore.jks
+- kafka-2.keystore.jks
+
+## PEM certificates
+
+You can copy here your PEM certificates so a secret is created including them. Remember to use a CA (`kafka.truststore.pem`) and one certificate (`kafka.keystore.pem`) and key (`kafka.keystore.key`) per Kafka broker you have in the cluster. For instance, if you have 3 brokers you need to copy here the following files:
+
+- kafka.truststore.pem
+- kafka-0.keystore.pem
+- kafka-0.keystore.key
+- kafka-1.keystore.pem
+- kafka-1.keystore.key

+# ZooKeeper
+
+[ZooKeeper](https://zookeeper.apache.org/) is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or other by distributed applications.
+
+## TL;DR
+
+```console
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm install my-release bitnami/zookeeper
+```
+
+## Introduction
+
+This chart bootstraps a [ZooKeeper](https://github.com/bitnami/bitnami-docker-zookeeper) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
+
+Bitnami charts can be used with [Kubeapps](https://kubeapps.com/) for deployment and management of Helm Charts in clusters. This Helm chart has been tested on top of [Bitnami Kubernetes Production Runtime](https://kubeprod.io/) (BKPR). Deploy BKPR to get automated TLS certificates, logging and monitoring for your applications.
+
+## Prerequisites
+
+- Kubernetes 1.12+
+- Helm 3.1.0
+- PV provisioner support in the underlying infrastructure
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+$ helm repo add bitnami https://charts.bitnami.com/bitnami
+$ helm install my-release bitnami/zookeeper
+```
+
+These commands deploy ZooKeeper on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```console
+$ helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Parameters
+
+The following tables lists the configurable parameters of the ZooKeeper chart and their default values per section/component:

+> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```console
+$ helm install my-release -f values.yaml bitnami/zookeeper
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Configuration and installation details
+
+### [Rolling vs Immutable tags](https://docs.bitnami.com/containers/how-to/understand-rolling-tags-containers/)
+
+It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
+
+Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.
+
+### Configure log level
+
+You can configure the ZooKeeper log level using the `ZOO_LOG_LEVEL` environment variable. By default, it is set to `ERROR` because of each readiness probe produce an `INFO` message on connection and a `WARN` message on disconnection.
+
+## Persistence
+
+The [Bitnami ZooKeeper](https://github.com/bitnami/bitnami-docker-zookeeper) image stores the ZooKeeper data and configurations at the `/bitnami/zookeeper` path of the container.
+
+Persistent Volume Claims are used to keep the data across deployments. This is known to work in GCE, AWS, and minikube. See the [Parameters](#parameters) section to configure the PVC or to disable persistence.
+
+If you encounter errors when working with persistent volumes, refer to our [troubleshooting guide for persistent volumes](https://docs.bitnami.com/kubernetes/faq/troubleshooting/troubleshooting-persistence-volumes/).
+
+### Adjust permissions of persistent volume mountpoint
+
+As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
+
+By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.
+As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
+
+You can enable this initContainer by setting `volumePermissions.enabled` to `true`.
+
+### Configure the data log directory
+
+You can use a dedicated device for logs (instead of using the data directory) to help avoiding competition between logging and snaphots. To do so, set the `dataLogDir` parameter with the path to be used for writing transaction logs. Alternatively, set this parameter with an empty string and it will result in the log being written to the data directory (Zookeeper's default behavior).
+
+When using a dedicated device for logs, you can use a PVC to persist the logs. To do so, set `persistence.enabled` to `true`. See the [Persistence Parameters](#persistence-parameters) section for more information.
+
+### Set pod affinity
+
+This chart allows you to set custom pod affinity using the `affinity` parameter. Find more information about pod affinity in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).
+
+As an alternative, you can use any of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/master/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

+- `service.tls.client_port` is renamed to `service.tlsClientPort`
+- `service.tls.client_enable` is renamed to `tls.client.enabled`
+- `service.tls.client_keystore_path` is renamed to `tls.client.keystorePath`
+- `service.tls.client_truststore_path` is renamed to `tls.client.truststorePath`
+- `service.tls.client_keystore_password` is renamed to `tls.client.keystorePassword`
+- `service.tls.client_truststore_password` is renamed to `tls.client.truststorePassword`
+- `service.tls.quorum_enable` is renamed to `tls.quorum.enabled`

+
+### 6.1.0
+
+This version introduces `bitnami/common`, a [library chart](https://helm.sh/docs/topics/library_charts/#helm) as a dependency. More documentation about this new utility could be found [here](https://github.com/bitnami/charts/tree/master/bitnami/common#bitnami-common-library-chart). Please, make sure that you have updated the chart dependencies before executing any upgrade.
+
+### To 6.0.0
+
+[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
+
+[Learn more about this change and related upgrade considerations](https://docs.bitnami.com/kubernetes/infrastructure/zookeeper/administration/upgrade-helm3/).
+
+### To 5.21.0
+
+A couple of parameters related to Zookeeper metrics were renamed or disappeared in favor of new ones:
+
+- `metrics.port` is renamed to `metrics.containerPort`.
+- `metrics.annotations` is deprecated in favor of `metrics.service.annotations`.
+
+### To 3.0.0
+
+This new version of the chart includes the new ZooKeeper major version 3.5.5. Note that to perform an automatic upgrade
+of the application, each node will need to have at least one snapshot file created in the data directory. If not, the
+new version of the application won't be able to start the service. Please refer to [ZOOKEEPER-3056](https://issues.apache.org/jira/browse/ZOOKEEPER-3056)
+in order to find ways to workaround this issue in case you are facing it.
+
+### To 2.0.0
+
+Backwards compatibility is not guaranteed unless you modify the labels used on the chart's statefulsets.
+Use the workaround below to upgrade from versions previous to 2.0.0. The following example assumes that the release name is `zookeeper`:
+
+```console
+$ kubectl delete statefulset zookeeper-zookeeper --cascade=false
+```
+
+### To 1.0.0
+
+Backwards compatibility is not guaranteed unless you modify the labels used on the chart's deployments.
+Use the workaround below to upgrade from versions previous to 1.0.0. The following example assumes that the release name is zookeeper:
+
+```console
+$ kubectl delete statefulset zookeeper-zookeeper --cascade=false
+```
