TL;DR

helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/rabbitmq-cluster-operator

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository.

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 RabbitMQ Cluster Operator Deployment in a Kubernetes cluster using the Helm package manager.

Bitnami charts can be used with Kubeapps for deployment and management of Helm Charts in clusters.

Prerequisites

Kubernetes 1.23+
Helm 3.8.0+
PV provisioner support in the underlying infrastructure

Installing the Chart

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

helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/rabbitmq-cluster-operator

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

The command deploy the RabbitMQ Cluster Kubernetes Operator on the Kubernetes cluster in the default configuration. The Parameters section lists the parameters that can be configured during installation.

Tip: List all releases using helm list

Differences between the Bitnami RabbitMQ chart and the Bitnami RabbitMQ Operator chart

In the Bitnami catalog we offer both the bitnami/rabbitmq and bitnami/rabbitmq-operator charts. Each solution covers different needs and use cases.

The bitnami/rabbitmq chart deploys a single RabbitMQ installation using a Kubernetes StatefulSet object (together with Services, PVCs, ConfigMaps, etc.). The figure below shows the deployed objects in the cluster after executing helm install:

                    +--------------+             +-----+
                    |              |             |     |
 Service            |   RabbitMQ   +<------------+ PVC |
<-------------------+              |             |     |
                    |  StatefulSet |             +-----+
                    |              |
                    +-----------+--+
                                ^                +------------+
                                |                |            |
                                +----------------+ Configmaps |
                                                 | Secrets    |
                                                 +------------+

Its lifecycle is managed using Helm and, at the RabbitMQ container level, the following operations are automated: persistence management, configuration based on environment variables and plugin initialization. The StatefulSet do not require any ServiceAccounts with special RBAC privileges so this solution would fit better in more restricted Kubernetes installations.

The bitnami/rabbitmq-operator chart deploys a RabbitMQ Operator installation using a Kubernetes Deployment. The figure below shows the RabbitMQ operator deployment after executing helm install:

+--------------------+
|                    |      +---------------+
|  RabbitMQ Operator |      |               |

        |   +-----------------+     |
        +---+ Service Account +<----+
            +-----------------+

The operator will extend the Kubernetes API with the following object: RabbitmqCluster. From that moment, the user will be able to deploy objects of these kinds and the previously deployed Operator will take care of deploying all the required StatefulSets, ConfigMaps and Services for running a RabbitMQ instance. Its lifecycle is managed using kubectl on the RabbitmqCluster objects. The following figure shows the deployed objects after deploying a RabbitmqCluster object using kubectl:

       -------------------------------------------------------------------------

This solution allows to easily deploy multiple RabbitMQ instances compared to the bitnami/rabbitmq chart. As the operator automatically deploys RabbitMQ installations, the RabbitMQ Operator pods will require a ServiceAccount with privileges to create and destroy multiple Kubernetes objects. This may be problematic for Kubernetes clusters with strict role-based access policies.

Configuration and installation details

Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the resources value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the resourcesPreset values, which automatically sets the resources section according to different presets. Check these presets in the bitnami/common chart. However, in production workloads using resourcePreset is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the official Kubernetes documentation.

Rolling VS Immutable tags

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Additional environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the extraEnvVars property.

rabbitmq-cluster-operator:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the extraEnvVarsCM or the extraEnvVarsSecret values.

Sidecars

If additional containers are needed in the same pod as rabbitmq-cluster-operator (such as additional metrics or logging exporters), they can be defined using the sidecars parameter.

sidecars:
- name: your-image-name
  image: your-image
  imagePullPolicy: Always
  ports:
  - name: portname
    containerPort: 1234

If these sidecars export extra ports, extra port definitions can be added using the service.extraPorts parameter (where available), as shown in the example below:

service:
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311

NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the --enable-metrics=true parameter at deployment time. The sidecars parameter should therefore only be used for any extra sidecar containers.

If additional init containers are needed in the same pod, they can be defined using the initContainers parameter. Here is an example:

initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234

Learn more about sidecar containers and init containers.

Pod affinity

This chart allows you to set your custom affinity using the affinity parameter. Find more information about Pod affinity in the kubernetes documentation.

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the bitnami/common chart. To do so, set the podAffinityPreset, podAntiAffinityPreset, or nodeAffinityPreset parameters.

Deploying extra resources

There are cases where you may want to deploy extra objects, such your custom RabbitmqCluster objects. For covering this case, the chart allows adding the full specification of other objects using the extraDeploy parameter.

For instance, to deploy your custom RabbitmqCluster definition, you can install the RabbitMQ Cluster Operator using the values below:

extraDeploy:
  - apiVersion: rabbitmq.com/v1beta1
    kind: RabbitmqCluster
    metadata:
      name: rabbitmq-custom-configuration
    spec:
      replicas: 1
      rabbitmq:
        additionalConfig: |
          log.console.level = debug

cert-manager parameters

Name	Description	Value
`useCertManager`	Deploy cert-manager objects (Issuer and Certificate) for webhooks	`false`

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

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

helm install my-release \
  --set livenessProbe.enabled=false \
    oci://REGISTRY_NAME/REPOSITORY_NAME/rabbitmq-cluster-operator

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.

The above command disables the Operator liveness probes.

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

helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/rabbitmq-cluster-operator

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts. Tip: You can use the default values.yaml

Upgrading

Upgrading CRDs

By design, the helm upgrade command will not upgrade the CustomResourceDefinition objects, as stated in their official documentation. This is done to avoid the potential risks of upgrading CRD objects, such as data loss.

In order to upgrade the CRD objects, perform the following steps:

Perform a backup of your running RabbitMQ instances following the official documentation.
Execute the following commands (replace the VERSION placeholder):

helm fetch bitnami/rabbitmq-cluster-operator --version VERSION
tar xf rabbitmq-cluster-operator-VERSION.tar.gz
kubectl apply -f rabbitmq-cluster-operator/crds

To 4.0.0

This major bump changes the following security defaults:

resourcesPreset is changed from none to the minimum size working in our test suites (NOTE: resourcesPreset is not meant for production usage, but resources adapted to your use case).
global.compatibility.openshift.adaptSecurityContext is changed from disabled to auto.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

To 2.0.0

This new version adds the following components:

RabbitMQ Messaging Topology Operator: all the settings are inside the msgTopologyOperator section.
RabbitMQ Default User Credential Updater sidecar: this enables Hashicorp Vault integration for all RabbitMQCluster instances.
cert-manager subchart: this is necessary for the RabbitMQ Messaging Topology Webhooks to work.

As a breaking change, all rabbitmq-cluster-operator deployment values were moved to the clusterOperator section.

No issues are expected during upgrades.

To 1.0.0

The CRD was updated according to the latest changes in the upstream project. Thanks to the improvements in the latest changes, the CRD is not templated anymore and can be placed under the crds directory following Helm best practices for CRDS.

You need to manually delete the old CRD before upgrading the release.

kubectl delete crd rabbitmqclusters.rabbitmq.com
helm upgrade my-release oci://REGISTRY_NAME/REPOSITORY_NAME/rabbitmq-cluster-operator

Note: You need to substitute the placeholders REGISTRY_NAME and REPOSITORY_NAME with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use REGISTRY_NAME=registry-1.docker.io and REPOSITORY_NAME=bitnamicharts.
