Chapter 13. Adding custom SSL/TLS certificates when Red Hat Quay is deployed on Kubernetes
When deployed on Kubernetes, Red Hat Quay mounts in a secret as a volume to store config assets. Currently, this breaks the upload certificate function of the superuser panel.
As a temporary workaround, base64 encoded certificates can be added to the secret after Red Hat Quay has been deployed.
Use the following procedure to add custom SSL/TLS certificates when Red Hat Quay is deployed on Kubernetes.
Prerequisites
- Red Hat Quay has been deployed.
-
You have a custom
ca.crtfile.
Procedure
Base64 encode the contents of an SSL/TLS certificate by entering the following command:
$ cat ca.crt | base64 -w 0
Example output
...c1psWGpqeGlPQmNEWkJPMjJ5d0pDemVnR2QNCnRsbW9JdEF4YnFSdVd3PT0KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQo=
Enter the following
kubectlcommand to edit thequay-enterprise-config-secretfile:$ kubectl --namespace quay-enterprise edit secret/quay-enterprise-config-secret
Add an entry for the certificate and paste the full
base64encoded stringer under the entry. For example:custom-cert.crt: c1psWGpqeGlPQmNEWkJPMjJ5d0pDemVnR2QNCnRsbW9JdEF4YnFSdVd3PT0KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQo=
Use the
kubectl deletecommand 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
Afterwards, the Red Hat Quay deployment automatically schedules replace pods with the new certificate data.
