Deploy cert-manager

In this section you will deploy cert-manager. cert-manager is going to manage SSL certificates for you, either self-signed or issued by Let's Encrypt.


If you already have an SSL certificate you are managing yourself, you may proceed to the What's Next section.

What You'll Need


  1. Go to your GitOps repository, inside your rok-tools management environment:

    root@rok-tools:~# cd ~/ops/deployments
  2. Edit rok/cert-manager/cert-manager/overlays/deploy/kustomization.yaml and enable both self-signed and Let's Encrypt ClusterIssuers:

    - cluster-issuer-self-signed.yaml
    - cluster-issuer-letsencrypt-prod.yaml
  3. Edit rok/cert-manager/cert-manager/overlays/deploy/cluster-issuer-letsencrypt-prod.yaml to set a valid email for your ACME account:

        email:  # <-- Update this line with a valid email address
  4. Commit your changes:

    root@rok-tools:~/ops/deployments# git commit -am "Configure cert-manager"
  5. Install cert-manager resources along with the two ClusterIssuers:

    root@rok-tools:~/ops/deployments# rok-deploy --apply rok/cert-manager/cert-manager/overlays/deploy


  1. Verify that cert-manager is up-and-running. Check that field READY is 1/1 for the corresponding deployments:

    root@rok-tools:~/ops/deployments# kubectl get deploy -n cert-manager
    NAME                      READY   UP-TO-DATE   AVAILABLE   AGE
    cert-manager              1/1     1            1           1m
    cert-manager-cainjector   1/1     1            1           1m
    cert-manager-webhook      1/1     1            1           1m
  2. Verify that your ACME account was registered successfully by inspecting the status condition on the Let's Encrypt ClusterIssuer:

    root@rok-tools:~/ops/deployments# kubectl describe clusterissuer letsencrypt-prod
        Message:               The ACME account was registered with the ACME server
        Reason:                ACMEAccountRegistered
        Status:                True
        Type:                  Ready


You have successfully installed cert-manager and configured it with a self-signed and a Let's Encrypt ClusterIssuer.

What's Next

The next step is to expose Istio, our service mesh.
