Chapter 10. Adding custom SSL/TLS certificates when Red Hat Quay is deployed on Kubernetes


To add custom SSL/TLS certificates to your Red Hat Quay deployment on Kubernetes, you can base64 encode the certificate, add it to the config secret, and restart the pods. This procedure works around the limitation where the superuser panel certificate upload function does not work with Kubernetes deployments.

Prerequisites

  • Red Hat Quay has been deployed.
  • You have a custom ca.crt file.

Procedure

  1. Base64 encode the contents of an SSL/TLS certificate by entering the following command:

    $ cat ca.crt | base64 -w 0
    Copy to Clipboard Toggle word wrap

    Example output

    ...c1psWGpqeGlPQmNEWkJPMjJ5d0pDemVnR2QNCnRsbW9JdEF4YnFSdVd3PT0KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQo=
    Copy to Clipboard Toggle word wrap

  2. Enter the following kubectl command to edit the quay-enterprise-config-secret file:

    $ kubectl --namespace quay-enterprise edit secret/quay-enterprise-config-secret
    Copy to Clipboard Toggle word wrap
  3. Add an entry for the certificate and paste the full base64 encoded stringer under the entry. For example:

      custom-cert.crt:
    c1psWGpqeGlPQmNEWkJPMjJ5d0pDemVnR2QNCnRsbW9JdEF4YnFSdVd3PT0KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQo=
    Copy to Clipboard Toggle word wrap
  4. Use the kubectl delete command to remove all Red Hat Quay pods. For example:

    $ kubectl delete pod quay-operator.v3.7.1-6f9d859bd-p5ftc quayregistry-clair-postgres-7487f5bd86-xnxpr quayregistry-quay-app-upgrade-xq2v6  quayregistry-quay-database-859d5445ff-cqthr quayregistry-quay-redis-84f888776f-hhgms
    Copy to Clipboard Toggle word wrap

    Afterwards, the Red Hat Quay deployment automatically schedules replace pods with the new certificate data.
