# 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: ### Global parameters | Parameter | Description | Default | |---------------------------|-------------------------------------------------|---------------------------------------------------------| | `global.imageRegistry` | Global Docker image registry | `nil` | | `global.imagePullSecrets` | Global Docker registry secret names as an array | `[]` (does not add image pull secrets to deployed pods) | | `global.storageClass` | Global storage class for dynamic provisioning | `nil` | ### Common parameters | Parameter | Description | Default | |---------------------|---------------------------------------------------|---------------------------------| | `nameOverride` | String to partially override kafka.fullname | `nil` | | `fullnameOverride` | String to fully override kafka.fullname | `nil` | | `clusterDomain` | Default Kubernetes cluster domain | `cluster.local` | | `commonLabels` | Labels to add to all deployed objects | `{}` | | `commonAnnotations` | Annotations to add to all deployed objects | `{}` | | `extraDeploy` | Array of extra objects to deploy with the release | `nil` (evaluated as a template) | ### Kafka parameters | Parameter | Description | Default | |-------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------| | `image.registry` | Kafka image registry | `docker.io` | | `image.repository` | Kafka image name | `bitnami/kafka` | | `image.tag` | Kafka image tag | `{TAG_NAME}` | | `image.pullPolicy` | Kafka image pull policy | `IfNotPresent` | | `image.pullSecrets` | Specify docker-registry secret names as an array | `[]` (does not add image pull secrets to deployed pods) | | `image.debug` | Set to true if you would like to see extra information on logs | `false` | | `config` | Configuration file for Kafka. Auto-generated based on other parameters when not specified (see [below](#setting-custom-parameters)) | `nil` | | `existingConfigmap` | Name of existing ConfigMap with Kafka configuration (see [below](#setting-custom-parameters)) | `nil` | | `hostAliases` | Add deployment host aliases | `[]` | | `log4j` | An optional log4j.properties file to overwrite the default of the Kafka brokers. | `nil` | | `existingLog4jConfigMap` | The name of an existing ConfigMap containing a log4j.properties file. | `nil` | | `heapOpts` | Kafka's Java Heap size | `-Xmx1024m -Xms1024m` | | `deleteTopicEnable` | Switch to enable topic deletion or not | `false` | | `autoCreateTopicsEnable` | Switch to enable auto creation of topics. Enabling auto creation of topics not recommended for production or similar environments | `false` | | `logFlushIntervalMessages` | The number of messages to accept before forcing a flush of data to disk | `_10000` | | `logFlushIntervalMs` | The maximum amount of time a message can sit in a log before we force a flush | `1000`
