Memcached is an in-memory key-value store for small chunks of arbitrary data (strings, objects) from results of database calls, API calls, or page rendering.

TL;DR;

$ helm install memcached-x.x.x.tgz

Introduction

Bitnami charts for Helm are carefully engineered, actively maintained and are the quickest and easiest way to deploy containers on a Kubernetes cluster that are ready to handle production workloads.

This chart bootstraps a Memcached deployment on a Kubernetes cluster using the Helm package manager.

Get this chart

Download the latest release of the chart from the releases page.

Alternatively, clone the repo if you wish to use the development snapshot:

$ git clone https://github.com/bitnami/charts.git

Installing the Chart

To install the chart with the release name my-release:

$ helm install --name my-release memcached-x.x.x.tgz

Replace the x.x.x placeholder with the chart release version.

The command deploys Memcached on the Kubernetes cluster in the default configuration. The configuration 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:

$ helm delete my-release

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

The following tables lists the configurable parameters of the Memcached chart and their default values.

Parameter	Description	Default
`imageTag`	`bitnami/memcached` image tag	Memcached image version
`imagePullPolicy`	Image pull policy	`Always` if `imageTag` is `latest`, else `IfNotPresent`
`memcachedUser`	Memcached admin user	`nil`
`memcachedPassword`	Memcached admin password	`nil`

The above parameters map to the env variables defined in bitnami/memcached. For more information please refer to the bitnami/memcached image documentation.

Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

$ helm install --name my-release \
  --set memcachedUser=user,memcachedPassword=password \
    memcached-x.x.x.tgz

The above command sets the Memcached admin account username and password to user and password respectively.

Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,

$ helm install --name my-release -f values.yaml memcached-x.x.x.tgz

Tip

: You can use the default values.yaml
