Docker registry access
You must ensure that the OpenShift cluster has access to the Docker Container registry from where it retrieves the container images for deployment.
If a local registry is set up for the OpenShift cluster, follow the instructions during the installation to copy the Cloudera container images from the Cloudera hosted registry to this local registry. For more information, see Installing in air gap environment.
Only TLS-enabled custom Docker Registry is supported. Ensure that you use a TLS certificate to secure the custom Docker Registry. The TLS certificate can be self-signed, or signed by a private or public trusted Certificate Authority (CA).
Alternatively, you can use the Cloudera hosted Docker Registry. But using the Cloudera hosted Docker Registry option may increase time to deploy or start the services in the cluster. Cloudera generates Docker Registry credentials that are identical to your paywall credentials. Refer to your welcome letter for the credentials or use the credential generator on cloudera.com to generate credentials from your license key.
