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:v3.8.15 "/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. Add certs when deployed on Kubernetes
When deployed on Kubernetes, Red Hat Quay mounts in a secret as a volume to store config assets. Unfortunately, this currently breaks the upload certificate function of the superuser panel.
To get around this error, a base64 encoded certificate can be added to the secret after Red Hat Quay has been deployed. Here’s how:
Begin by base64 encoding the contents of the certificate:
$ cat ca.crt -----BEGIN CERTIFICATE----- MIIDljCCAn6gAwIBAgIBATANBgkqhkiG9w0BAQsFADA5MRcwFQYDVQQKDA5MQUIu TElCQ09SRS5TTzEeMBwGA1UEAwwVQ2VydGlmaWNhdGUgQXV0aG9yaXR5MB4XDTE2 MDExMjA2NTkxMFoXDTM2MDExMjA2NTkxMFowOTEXMBUGA1UECgwOTEFCLkxJQkNP UkUuU08xHjAcBgNVBAMMFUNlcnRpZmljYXRlIEF1dGhvcml0eTCCASIwDQYJKoZI [...] -----END CERTIFICATE----- $ cat ca.crt | base64 -w 0 [...] c1psWGpqeGlPQmNEWkJPMjJ5d0pDemVnR2QNCnRsbW9JdEF4YnFSdVd3PT0KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQo=
Use the
kubectltool to edit the quay-enterprise-config-secret.$ kubectl --namespace quay-enterprise edit secret/quay-enterprise-config-secret
Add an entry for the cert and paste the full base64 encoded string under the entry:
custom-cert.crt: c1psWGpqeGlPQmNEWkJPMjJ5d0pDemVnR2QNCnRsbW9JdEF4YnFSdVd3PT0KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQo=
-
Finally, recycle all Red Hat Quay pods. Use
kubectl deleteto remove all Red Hat Quay pods. The Red Hat Quay Deployment will automatically schedule replacement pods with the new certificate data.
