deepracer-simapp

Use when: updating Dockerfile.upstream or Dockerfile.upstream-adjusted to a new deepracer-on-aws-simapp version; syncing changes from a new upstream ECR image; inspecting docker image layers to find version bumps; reverse-engineering changes between simapp image versions.

Re-tag an image in a Public ECR repository without downloading it. Use when you need to add a new tag to an existing image in a public.ecr.aws repo, copy a tag, or alias a version tag (e.g. point v1.2.0 at the same image as v1.2.1).
