Chapter 2. Enabling the Argo CD plugin

Prerequisites

• Add Argo CD instance information to your app-config.yaml configmap as shown in the following example:

  argocd:
    appLocatorMethods:
      - type: 'config'
        instances:
          - name: argoInstance1
            url: https://argoInstance1.com
            username: ${ARGOCD_USERNAME}
            password: ${ARGOCD_PASSWORD}
          - name: argoInstance2
            url: https://argoInstance2.com
            username: ${ARGOCD_USERNAME}
            password: ${ARGOCD_PASSWORD}

• Add the following annotation to the entity’s catalog-info.yaml file to identify the Argo CD applications.

  annotations:
    ...
    # The label that Argo CD uses to fetch all the applications. The format to be used is label.key=label.value. For example, rht-gitops.com/janus-argocd=quarkus-app.
  
    argocd/app-selector: '${ARGOCD_LABEL_SELECTOR}'

• (Optional) Add the following annotation to the entity’s catalog-info.yaml file to switch between Argo CD instances as shown in the following example:

   annotations:
     ...
      # The Argo CD instance name used in `app-config.yaml`.
  
      argocd/instance-name: '${ARGOCD_INSTANCE}'

  Note

  If you do not set this annotation, the Argo CD plugin defaults to the first Argo CD instance configured in app-config.yaml.
