Add Docker Registry Credentials

To enable CDSW to fetch custom engines from a secure repository, as Administrator you need to add Docker registry credentials.

Create a kubectl secret named regcred for your secured Docker registry.

The following command creates the secret in your Kubernetes cluster:

kubectl create secret docker-registry regcred 
--docker-server=<server host> --docker-username=<username> 
--docker-password=<password> -n <compute namespace eg. default>

Retrieve the above secret as a yaml file by entering the following:

kubectl get secret regcred --output=yaml -n 
<compute namespace eg. default> > k8s-secret-regcred.yaml

Place the yaml file in the master node located at /etc/cdsw/patches.
Set the file visibility for root only.
Restart CDSW service to pick up the new secret.
Launch a Session>Model>Job>Experiment using the engine image from the secured Docker registry.
