ndo-ship.sh — local build → artifactory → k8s deploy for NDO services.

Commands:
  doctor                       check docker/buildx/registry-login/kubectl
  login                        docker login to artifactory (interactive)
  tag      <service>           print the image ref that would be built
  test     <service>           run unit tests only (maven, or docker --target test)
  build    <service>           build the image (runs unit tests first unless --skip-tests)
  push     <service>           push the last built (or --tag'd) image
  deploy   <service> -e ENV    point <service>-v1 at the image + wait for rollout  [needs --yes]
  ship     <service> -e ENV    test → build → push → deploy → rollout wait          [needs --yes]
  status   <service> -e ENV    deployed image, replicas, pod state
  rollback <service> -e ENV    restore the image recorded before the last deploy   [needs --yes]
  pullsecret <service> -e ENV  attach local docker creds as an imagePullSecret (ImagePullBackOff fix) [needs --yes]

Options:
  -e, --env ALIAS     target env (see: ndo-api.sh env ls). Ambiguous short names are rejected.
  -t, --tag TAG       image tag (default: UTC timestamp, always unique)
      --ticket N      UNM number for the repo name (default: parsed from git branch)
  -d, --dir PATH      service repo (default: $NDO_PROJECTS/<service>)
  -f, --file FILE     dockerfile (default: Dockerfile_local, falls back to Dockerfile)
      --target STAGE  build target (default: release; ignored if the dockerfile has no stages)
      --platform P    default linux/amd64 — do NOT drop this on an arm64 Mac
      --skip-tests    skip unit tests in build/ship
      --no-cache      docker build --no-cache
      --timeout D     rollout wait (default 10m)
  -y, --yes           confirm a cluster-mutating command (deploy/ship/rollback/pullsecret)
