Chapter 5. Add a TLS certificate issuer


To secure communication to your Gateways, you must define a certification authority as an issuer for TLS certificates.

Note

This example uses the Let’s Encrypt TLS certificate issuer for simplicity, but you can use any certificate issuer supported by cert-manager. In multicluster environments, you must add your TLS issuer in each OpenShift cluster.

Procedure

  1. Enter the following command to define a TLS certificate issuer:

    kubectl apply -f - <<EOF
    apiVersion: cert-manager.io/v1
    kind: ClusterIssuer
    metadata:
      name: ${KUADRANT_CLUSTER_ISSUER_NAME}
    spec:
      selfSigned: {}
    EOF
    Copy to Clipboard Toggle word wrap
  2. Wait for the ClusterIssuer to become ready as follows:

    kubectl wait clusterissuer/${KUADRANT_CLUSTER_ISSUER_NAME} --for=condition=ready=true
    Copy to Clipboard Toggle word wrap
