Option 1: Use Oracle Container Registry

On your development host, create a Kubernetes image pull secret in your Kubernetes cluster. A Kubernetes Secret takes a copy of your credentials from a docker login command and makes them available to your Kubernetes cluster.

When you completed Task 3: Pull Container Image from Oracle Container Registry to Your Development Host in Option 1: Get Container Image from Oracle Container Registry, you performed the docker login command.

1. (Optional): Confirm the credentials are stored in the config.json file.

   cat $HOME/.docker/config.json

   The output contains the auth token for container-registry.oracle.com.

   {
           "auths": {
                   "container-registry.oracle.com": {
                           "auth": "z1SbLO4JgwqzLEn1ZxJ"}
                   
                    }
   }

2. Create the image pull secret. This example creates the sekret secret.

   kubectl create secret generic sekret \
   --from-file=.dockerconfigjson=$HOME/.docker/config.json \
   --type=kubernetes.io/dockerconfigjson

3. (Optional): Confirm the Secret is created in your Kubernetes cluster.

   kubectl get secrets
   NAME                               TYPE                             DATA   AGE
   sekret                             kubernetes.io/dockerconfigjson   1      1d
   

Note:

Save the name of the Secret. You need it later.
