Push the docker image to the IBM Cloud Container Registry

Before you can deploy the application on the cluster, you first need to push the Docker image to the IBM Cloud private container registry.

1. Log in to the private Container Registry of IBM Cloud. Only required if you haven't ibmcloud login before.

    ibmcloud cr login
   

   ibmcloud cr login is a wrapper for docker login , it is only needed to log your local docker daemon into the registry, which enables you to push/pull images.

2. Retrieve the namespace for the image registry that was created for you.

    ibmcloud cr namespace-list
   

   You should get a namespace called pyrk8s

3. Push the image to your private image registry.

    docker push <region>.icr.io/<namespace>/todo-<lastname>:1.0
   

   Region is us for the Dallas datacenter.

> If you get the error `unauthorized: authentication required`, run the command **ibmcloud cr login**

1. Verify that the image was successfully added to your registry in your namespace

    ibmcloud cr images
   

   Output:

    Listing images...
   
    REPOSITORY                                  NAMESPACE   TAG       DIGEST         CREATED        SIZE     VULNERABILITY STATUS
    de.icr.io/lab-registry/todo-mace   namespace   1   0d90cb732881   1 minute ago   264 MB   OK
   

2. The image is also visible in the IBM Cloud Console. Go to the Container Registry.
