To utilize an account deploy key, you'll need to log in differently with your docker client:

  1. Log in to your account, and select "Account" from the profile dropdown window.
  2. In the Account sub-navigation dropdown, select Deploy Keys.
  3. Type in the confirmation text and click through to generate a new key. NOTE: This will only be shown once and cannot be recovered.  If your deploy key is lost, you will need to generate a new key.  THIS WILL DESTROY YOUR EXISTING KEY.  A warning will be shown on the page if you have an outstanding key.
  4. Open a command line on a workstation/server with Docker installed, with a user that has access to the Docker CLI.
  5. User the docker CLI to log into the registry with these specific additions: docker login --username=deploy+yourcanisterID --password=deployKey cloud.canister.io:5000 and hit enter.  You MUST prepend your username with "deploy+".  
  6. You will now have read-only/pull access to your registry account.
