# Rebuild + redeploy a SINGLE compose service without touching the rest of the
# stack.  The whole-stack rebuild you keep hitting happens because `web-app`
# depends_on slmm + sfm, so `compose up --build web-app` rebuilds the entire
# dependency tree.  `--no-deps` is the fix: build + recreate ONLY this service.
#
# Usage:
#   ./redeploy.sh              # rebuild + redeploy web-app (prod-style, :8001)
#   ./redeploy.sh terra-view   # the dev container (:1001, bind-mounted source)
#   ./redeploy.sh sfm          # any single service
#
# Tip: the dev `terra-view` service bind-mounts the source, so for plain
# code/template edits you usually only need:  docker compose restart terra-view
# Rebuild it only when requirements.txt or the Dockerfile changed.
