RabbitMQ High Available

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


$ helm install stable/rabbitmq-ha


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


  • Kubernetes 1.5+ 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-ha

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

Upgrading the Chart

To upgrade the chart, you need to make sure that you are using the same value of the rabbitmqErlangCookie amongst the releases. If you didn't define it at the first place, you can upgrade using the following command:

$ export ERLANGCOOKIE=$(kubectl get secrets -n <NAMESPACE> <HELM_RELEASE_NAME>-rabbitmq-ha -o jsonpath="{.data.rabbitmq-erlang-cookie}" | base64 --decode)
$ helm upgrade \
    --set rabbitmqErlangCookie=$ERLANGCOOKIE \
    <HELM_RELEASE_NAME> stable/rabbitmq-ha

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.


The following table lists the configurable parameters of the RabbitMQ chart and their default values.

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 \

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-ha

Tip: You can use the default values.yaml

Custom ConfigMap

When creating a new chart with this chart as a dependency, existingConfigMap can be used to override the default configmap.yaml provided. It also allows for providing additional configuration files that will be mounted into /etc/rabbitmq. In the parent chart's values.yaml, set the value to true and provide the file [templates/configmap.yaml][] for your use case.

Example of using RabbitMQ definition to setup users, permissions or policies:

apiVersion: v1
kind: ConfigMap
  name: my-release-rabbitmq-ha
  enabled_plugins: |
  rabbitmq.conf: |
    # ....
    management.load_definitions = /etc/rabbitmq/definitions.json
  definitions.json: |
      "permissions": [],
      "users": [],
      "policies: []

Then, install the chart with the above configuration:

$ helm install --name my-release --set existingConfigMap=true stable/rabbitmq-ha

Custom Secret

Similar to custom ConfigMap, existingSecret can be used to override the default secret.yaml provided, and rabbitmqCert.existingSecret can be used to override the default certificates. The custom secret must provide the following keys:

  • rabbitmq-user
  • rabbitmq-password
  • rabbitmq-erlang-cookie
  • definitions.json (the name can be altered by setting the definitionsSource)

Prometheus Monitoring & Alerts

Prometheus and its features can be enabled by setting prometheus.enabled to true. See values.yaml for more details and configuration options
