Chapter 5. Adding TLS Certificates to the Red Hat Quay Container
To add custom TLS certificates to Red Hat Quay, create a new directory named extra_ca_certs/ beneath the Red Hat Quay config directory. Copy any required site-specific TLS certificates to this new directory.
5.1. Add TLS certificates to Red Hat Quay
View certificate to be added to the container
$ cat storage.crt -----BEGIN CERTIFICATE----- MIIDTTCCAjWgAwIBAgIJAMVr9ngjJhzbMA0GCSqGSIb3DQEBCwUAMD0xCzAJBgNV [...] -----END CERTIFICATE-----
Create certs directory and copy certificate there
$ mkdir -p quay/config/extra_ca_certs $ cp storage.crt quay/config/extra_ca_certs/ $ tree quay/config/ ├── config.yaml ├── extra_ca_certs │ ├── storage.crt
Obtain the
Quaycontainer’sCONTAINER IDwithpodman ps:$ sudo podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS 5a3e82c4a75f <registry>/<repo>/quay:v3.11.3 "/sbin/my_init" 24 hours ago Up 18 hours 0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp, 443/tcp grave_keller
Restart the container with that ID:
$ sudo podman restart 5a3e82c4a75f
Examine the certificate copied into the container namespace:
$ sudo podman exec -it 5a3e82c4a75f cat /etc/ssl/certs/storage.pem -----BEGIN CERTIFICATE----- MIIDTTCCAjWgAwIBAgIJAMVr9ngjJhzbMA0GCSqGSIb3DQEBCwUAMD0xCzAJBgNV
5.2. 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.
