4.2. Configuring annotations for monitoring

Procedure

1. As an administrator of the operator, edit the default configuration to add Prometheus annotations as follows:

   # Update OPERATOR_NS accordingly
   OPERATOR_NS=rhdh-operator
   kubectl edit configmap backstage-default-config -n "${OPERATOR_NS}"

2. Find the deployment.yaml key in the ConfigMap and add the annotations to the spec.template.metadata.annotations field as follows:

   deployment.yaml: |-
     apiVersion: apps/v1
     kind: Deployment
     # --- truncated ---
     spec:
       template:
         # --- truncated ---
         metadata:
           labels:
            rhdh.redhat.com/app:  # placeholder for 'backstage-<cr-name>'
           # --- truncated ---
           annotations:
             prometheus.io/scrape: 'true'
             prometheus.io/path: '/metrics'
             prometheus.io/port: '9464'
             prometheus.io/scheme: 'http'
     # --- truncated ---
