# CS374 Course Development Container -- compose file
# ---------------------------------------------------
# Put this file, together with the course Dockerfile, in a `.devcontainer/`
# folder INSIDE your cloned GitHub work repo:
#
#   cs374-work/                <-- your cloned GitHub repo
#     .devcontainer/
#       Dockerfile
#       docker-compose.yml     <-- this file
#       devcontainer.json
#     (your assignment work lives here, at the repo root)
#
# Then, from the .devcontainer/ folder:
#
#   docker compose build            # build the image (first time / after edits)
#   docker compose run --rm cs374   # open a shell inside the container
#
# `--rm` deletes the container when you exit; your files survive because
# they live in the bind-mounted repo on YOUR disk, not in the container.
