a. Log in to CircleCI server container registry

Access to the images you need for your installation requires you to use a username and token, which will be provided by CircleCI. Access the CircleCI support portal for more information.

docker login cciserver.azurecr.io --username <your-circleci-provided-username> --password <your-circleci-provided-token>

b. Download all images required for this release

Download all images required for the release of CircleCI server to your local machine. This list contains all required images for the Helm installation, the CircleCI Agent, and the Reality Check testing tool.
