RabbitMQ

RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol (AMQP).

TL;DR;

$ helm install stable/rabbitmq

Introduction

This chart bootstraps a RabbitMQ 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 stable/rabbitmq

The command deploys RabbitMQ 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 RabbitMQ chart and their default values.

Parameter	Description	Default
image	RabbitMQ image	bitnami/rabbitmq:{VERSION}
imagePullPolicy	Image pull policy	Always if imageTag is latest, else IfNotPresent.
rabbitmqUsername	RabbitMQ application username	user
rabbitmqPassword	RabbitMQ application password	random 10 character long alphanumeric string
rabbitmqErlangCookie	Erlang cookie	random 32 character long alphanumeric string
rabbitmqNodePort	Node port	5672
rabbitmqNodeType	Node type	stats
rabbitmqNodeName	Node name	rabbit
rabbitmqClusterNodeName	Node name to cluster with. e.g.: clusternode@hostname	nil
rabbitmqVhost	RabbitMQ application vhost	/
rabbitmqManagerPort	RabbitMQ Manager port	15672
rabbitmqDiskFreeLimit	Disk free limit	"6GiB"
serviceType	Kubernetes Service type	ClusterIP
persistence.enabled	Use a PVC to persist data	true
persistence.existingClaim	Use an existing PVC to persist data	nil
persistence.storageClass	Storage class of backing PVC	nil (uses alpha storage class annotation)
persistence.accessMode	Use volume as ReadOnly or ReadWrite	ReadWriteOnce
persistence.size	Size of data volume	8Gi
nodeSelector	Node labels for pod assignment	{}
affinity	Affinity settings for pod assignment	{}
tolerations	Toleration labels for pod assignment	[]

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

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

$ helm install --name my-release \
  --set rabbitmqUsername=admin,rabbitmqPassword=secretpassword,rabbitmqErlangCookie=secretcookie \
    stable/rabbitmq

The above command sets the RabbitMQ admin username and password to admin and secretpassword respectively. Additionally the secure erlang cookie is set to secretcookie.

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 stable/rabbitmq

Tip

: You can use the default values.yaml

Persistence

The Bitnami RabbitMQ image stores the RabbitMQ data and configurations at the /bitnami/rabbitmq path of the container.

The chart mounts a Persistent Volume volume at this location. By default, the volume is created using dynamic volume provisioning. An existing PersistentVolumeClaim can also be defined.

Existing PersistentVolumeClaims

1. Create the PersistentVolume
2. Create the PersistentVolumeClaim
3. Install the chart

$ helm install --set persistence.existingClaim=PVC_NAME rabbitmq
