Prerequsites

• You have installed and configured the @backstage/plugin-kubernetes and @backstage/plugin-kubernetes-backend dynamic plugins.
• You have configured the Kubernetes plugin to connect to the cluster using a ServiceAccount.

• The ClusterRole must be granted for custom resources (PipelineRuns and TaskRuns) to the ServiceAccount accessing the cluster.

  Note

  If you have the RHDH Kubernetes plugin configured, then the ClusterRole is already granted.

• To view the pod logs, you have granted permissions for pods/log.

• You can use the following code to grant the ClusterRole for custom resources and pod logs:

  kubernetes:
     ...
     customResources:
       - group: 'tekton.dev'
         apiVersion: 'v1'
         plural: 'pipelineruns'
       - group: 'tekton.dev'
         apiVersion: 'v1'
  
  
   ...
    apiVersion: rbac.authorization.k8s.io/v1
    kind: ClusterRole
    metadata:
      name: backstage-read-only
    rules:
      - apiGroups:
          - ""
        resources:
          - pods/log
        verbs:
          - get
          - list
          - watch
      ...
      - apiGroups:
          - tekton.dev
        resources:
          - pipelineruns
          - taskruns
        verbs:
          - get
          - list

  You can use the prepared manifest for a read-only ClusterRole, which provides access for both Kubernetes plugin and Tekton plugin.

• Add the following annotation to the entity’s catalog-info.yaml file to identify whether an entity contains the Kubernetes resources:

  annotations:
    ...
  
    backstage.io/kubernetes-id: <BACKSTAGE_ENTITY_NAME>

• You can also add the backstage.io/kubernetes-namespace annotation to identify the Kubernetes resources using the defined namespace.

  annotations:
    ...
  
    backstage.io/kubernetes-namespace: <RESOURCE_NS>

• Add the following annotation to the catalog-info.yaml file of the entity to enable the Tekton related features in RHDH. The value of the annotation identifies the name of the RHDH entity:

  annotations:
    ...
  
    janus-idp.io/tekton : <BACKSTAGE_ENTITY_NAME>

• Add a custom label selector, which RHDH uses to find the Kubernetes resources. The label selector takes precedence over the ID annotations.

  annotations:
    ...
  
    backstage.io/kubernetes-label-selector: 'app=my-app,component=front-end'

• Add the following label to the resources so that the Kubernetes plugin gets the Kubernetes resources from the requested entity:

  labels:
    ...
  
    backstage.io/kubernetes-id: <BACKSTAGE_ENTITY_NAME>

  Note

  When you use the label selector, the mentioned labels must be present on the resource.

Procedure

• The Tekton plugin is pre-loaded in RHDH with basic configuration properties. To enable it, set the disabled property to false as follows:

  global:
    dynamic:
      includes:
        - dynamic-plugins.default.yaml
      plugins:
        - package: ./dynamic-plugins/dist/janus-idp-backstage-plugin-tekton
          disabled: false

Prerequisites

• You have installed and configured the @backstage/plugin-kubernetes-backend dynamic plugins.
• You have configured the Kubernetes plugin to connect to the cluster using a ServiceAccount.

• The ClusterRole must be granted to ServiceAccount accessing the cluster.

  Note

  If you have the Developer Hub Kubernetes plugin configured, then the ClusterRole is already granted.

Procedure

• The Topology plugin is pre-loaded in Developer Hub with basic configuration properties. To enable it, set the disabled property to false as follows:

  app-config.yaml fragment

  auth:
  global:
    dynamic:
      includes:
        - dynamic-plugins.default.yaml
      plugins:
        - package: ./dynamic-plugins/dist/janus-idp-backstage-plugin-topology
          disabled: false

• forceDownload: Set to true to force a reinstall of the plugin, bypassing the cache. Default is false. For example, modify your dynamic-plugins.yaml file as follows:

  plugins:
    - disabled: false
      forceDownload: true
      package: 'oci://quay.io/example-org/example-plugin:v1.0.0!internal-backstage-plugin-example'

Prerequisites

• You have installed Red Hat Developer Hub by using either the Operator or Helm chart.
• You have an active Redis server. For more information on setting up an external Redis server, see the Redis official documentation.
