We tried to install OCP 4.12.18 on a lab cluster using the agent-based installer. Our install-config.yaml file included a private CA certificate that we wanted to add to the certificate trust bundle. This certificate had to be added to the trusted certificates so that a TLS connection can be opened from the OpenShift node to quay.io through the corporate proxy.

The install-config.yaml file:

We created a CD-ROM image

$ ./openshift-install --dir clusterconfigs agent create image

and booted the OpenShift nodes using this image. The nodes were not able to install due to:

As a workaround, we SSHed into the nodes during the installation and added our private CA certificate to the trust store manually:

$ vi /etc/pki/ca-trust/source/anchors/root.crt.pem
$ update-ca-trust

After that, the installation proceeded immediately and was eventually completed successfully.

We noticed that when the node was stuck trying to connect to quay.io, the file /etc/pki/ca-trust/source/anchors/openshift-config-user-ca-bundle.crt was empty. After the installation was completed, this file was filled with our private CA certificate automatically.

The OpenShift documentation doesn't tell whether an agent-based installer supports using custom CA certificates or not. Is this a supported feature?
