Documented steps

  1. Have (or build) an image in a registry accessible from Fly's builder (e.g. Docker Hub, GHCR, or fly registry).
  2. Ensure the app exists (fly launch --no-deploy or fly apps create) with a fly.toml.
  3. Run `fly deploy -i <registry/image:tag> -a <app>` to deploy that exact image.
  4. Alternatively use `fly deploy --image <ref>` with build flags disabled.
  5. Set env/secrets with `fly secrets set` if the image reads config from env.
  6. Control rollout strategy with --strategy and --wait-timeout as with source deploys.
