Mount custom cert in Delegate through ConfigMap

This knowledge base article walks you through how you can mount the custom cert with delegate through ConfigMap.

Steps to perform

1. Cert file as base 64 encoded or decoded .pem or .crt

   Example: test-cer.pem

   -----BEGIN CERTIFICATE-----
XXXXXXXXXXXXXXXXXXXXXXXXXXX
-----END CERTIFICATE-----

1. Create ConfigMap through Cert file

kubectl create configmap my-config --from-file=path/test-cer.pem

1. Now need to configure the volumes & volumeMount in the Deployment spec of Delegate Yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    harness.io/name: cert-test
  name: cert-test
  namespace: test-ng
spec:
  replicas: 1
  minReadySeconds: 120
  selector:
    matchLabels:
      harness.io/name: cert-test
  template:
    metadata:
      labels:
        harness.io/name: cert-test
      annotations:
        prometheus.io/scrape: "true"
        prometheus.io/port: "3460"
        prometheus.io/path: "/api/metrics"
    spec:
      terminationGracePeriodSeconds: 600
      restartPolicy: Always
      volumes:
      - name: my-config
        configMap: 
          name: my-config
      containers:
      - image: harness/delegate:23.06.79503
        volumeMounts: 
        - name: config
          mountPath: /opt/test/test-cer.pem

1. Now Apply the delegate yaml again

kubectl apply -f delegate.yaml
