Memcached
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 bitnami/memcached
Introduction
This chart bootstraps a Memcached deployment on a Kubernetes cluster using the Helm package manager.
Prerequisites
- Kubernetes 1.4+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure
Installing the Chart
To install the chart with the release name my-release:
$ helm install --name my-release bitnami/memcached
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 |
|---|---|---|
image.registry |
Memcached image registry | docker.io |
image.repository |
Memcached Image name | bitnami/memcached |
image.tag |
Memcached Image tag | {VERSION} |
image.pullPolicy |
Memcached image pull policy | Always if imageTag is latest, else IfNotPresent |
image.pullSecrets |
Specify image pull secrets | nil (does not add image pull secrets to deployed pods) |
memcachedUsername |
Memcached admin user | nil |
memcachedPassword |
Memcached admin password | nil |
serviceType |
Kubernetes Service type | ClusterIP |
resources |
CPU/Memory resource requests/limits | Memory: 256Mi, CPU: 250m |
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 bitnami/memcached
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 bitnami/memcached
Tip
: You can use the default values.yaml
