Issue

• We need to install a certificate chain as we use self signed certs in our internal docker registry.

Environment

• CloudBees Jenkins Enterprise - AWS/OpenStack/Anywhere

Resolution

To import the certificates in your cluster you have to use the certificates-update cluster operation

cje prepare certificates-update

then you have to copy your certificates and all certificates chain need in PROJECT_FOLDER/certificates, the certificate files must end with .pem extension. If the SSL certificate is self-signed or uses a custom certificate authority, it needs to be trusted by the workstation running the installation as well as copied to the machines part of the cluster.

Finally, you run cje apply and the certificated will be picked up automatically and installed on all VMs/containers involved in the cluster.
