- Around line 6-7: Update the ports mapping in the compose configuration to bind
port 8000 to loopback by using the documented 127.0.0.1:8000:8000 mapping
instead of exposing it on all host interfaces.
- Around line 9-16: Update the develop.watch configuration in compose.yaml to
watch only the API source and model paths, change that rule’s action from sync
to sync+restart so imported models reload, and add a separate rebuild rule for
requirements.txt changes.
In `@ML/Dockerfile`:
- Line 52: Update the Dockerfile CMD launching uvicorn to exec form so uvicorn
runs directly as PID 1 and receives shutdown signals reliably, while preserving
the existing api:app target, host, and port arguments.
- Line 19: Update the Dockerfile around WORKDIR and USER appuser so the /app
sync target and copied contents are writable by appuser before Compose Watch
runs. Move USER appuser after the file-copy steps, use COPY
--chown=appuser:appuser, or explicitly assign /app ownership while preserving
the existing build behavior.
In `@ML/README.Docker.md`:
- Around line 3-4: Update the Docker setup instructions in the README so users
first obtain or generate all three required model artifacts before running
docker compose up --build; document the concrete download or generation step and
ensure it accounts for the excluded data/ and train_model.py inputs.
- Around line 3-4: Update the documented Docker Compose startup command in the
README to include the --watch option alongside --build, using the existing
compose configuration’s develop.watch support.

Docker Compose file watch action sync+restart rebuild official documentation requirements.txt
💡 Result:
In Docker Compose, the "watch" functionality (configured under the develop key) allows you to automate service updates based on local file changes [1][2]. For files like requirements.txt that define dependencies, the rebuild action is the required approach because changing dependencies cannot typically be performed on-the-fly in a running container [3][4]. The official documentation specifically recommends using rebuild for requirements.txt [3]. How to configure watch for requirements.txt: You should define two separate rules in your compose.yaml file under the develop.watch section [1][2]: 1. For source code (e.g., Python files): Use action: sync to copy changes to the container without restarting or rebuilding [1][2]. 2. For dependency files (e.g., requirements.txt): Use action: rebuild to trigger an image rebuild and recreate the container whenever the file changes [3][4]. Example configuration: services: app: build:. develop: watch: - action: sync path:./src target: /app/src - action: rebuild path: requirements.txt When you run docker compose up --watch, Compose will monitor these paths [1][5]. If you modify a file in ./src, it will synchronize the file [1][2]. If you modify requirements.txt, it will automatically trigger a full image rebuild using BuildKit and recreate the container, ensuring your new dependencies are installed [1][3].

site:docs.docker.com/compose/how-tos/file-watch multiple watch rules same file path first matching rule ignore
💡 Result:
There is no universal standard for how file monitoring tools handle multiple rules for the same file path, as behavior depends entirely on the specific implementation or software being used. When multiple rules are defined for the same path in file monitoring or synchronization systems—such as Docker Compose watch—the system typically evaluates rules based on the specific configuration structure provided [1]. In configurations like Docker Compose, watch rules are defined as a list, and each entry functions independently based on its path and ignore patterns [1]. Ignore patterns in this context are applied relative to the specific path defined in that rule, meaning they do not necessarily conflict with global rules or rules in other sections unless explicitly nested or defined [1]. If you are encountering a situation where you believe a first-matching rule is ignoring subsequent rules, consider the following: 1. Rule Order: Some systems process lists of rules in the order they appear (sequentially). If a rule matches and triggers an ignore or an action, the system may stop processing further rules for that specific file event. 2. Scope: Check if your ignore rules are scoped globally or to a specific path. As seen in tools like Docker, ignore rules are often defined per-action or per-path [1]. 3. Specific Documentation: Because behavior is not standardized, you must consult the configuration manual for the specific tool you are using (e.g., rsync, inotify-tools, or a CI/CD pipeline) to determine if it employs a "first-match-wins" or "last-match-wins" logic.

Restart the API after source and model changes.
ML/api.py loads the model files at import time. ML/Dockerfile starts uvicorn without --reload, so action: sync does not reload the process. Scope the sync rule to source and model paths, use sync+restart, and add a separate rebuild rule for requirements.txt.

Docker Compose Watch action sync target directory must be writable by container user documentation
💡 Result:
Yes, when using the Docker Compose watch action with sync (or variations like sync+restart and sync+exec), the container's user must have write permissions for the specified target directory [1][2][3]. Docker Compose requires this write access so that it can successfully update files within the container's filesystem as changes are detected on the host [1][2]. If the container user lacks the necessary permissions, the synchronization process will fail [3]. To ensure your configuration works correctly, official documentation recommends the following best practices: 1. Use COPY --chown in your Dockerfile to ensure that the initial content placed into the target directory is owned by the appropriate, non-privileged user that the container will run as [1][2]. 2. If you are running the container as a non-privileged user, verify that both the directory exists and that the user has explicit write permissions to that location [1][2]. If the container user cannot write to the target directory, Compose will be unable to reflect the file synchronization, and you may encounter errors [3]. While ignore rules are useful for excluding files from being watched, they do not bypass filesystem permission requirements for the directories being scanned or targeted [4][5].

Make /app writable by appuser before using Compose Watch.
ML/compose.yaml syncs changes into /app. The Dockerfile switches to appuser before copying files, so /app and its contents remain root-owned. Compose Watch sync requires a writable target and can fail without it. Move USER appuser after the copies and use COPY --chown=appuser:appuser, or explicitly change /app ownership.

Use exec-form CMD for reliable shutdown.
This image has no ENTRYPOINT, so shell-form CMD runs /bin/sh -c as PID 1. The shell does not reliably forward stop signals to Uvicorn. Use exec form:

Document how the model artifacts are supplied before the build.
A fresh checkout has none of the three model files. .dockerignore also excludes data/ and train_model.py, so the Docker build cannot generate them before COPY models ./models. Add a tracked or released artifact step, or document an explicit generation or download step before docker compose up --build.

Docker Compose up --watch develop.watchdocumentation whetherdocker compose up --build starts watch
💡 Result:
The Docker Compose --watch flag, when used with docker compose up, is a mechanism to monitor source code for changes and automatically update running services based on rules defined in the develop.watch section of your Compose file [1][2]. Regarding your specific question about docker compose up --build and watch mode: 1. Starting Watch Mode: The command docker compose up --watch is specifically designed to build and start your services while simultaneously activating file watch mode [1]. 2. Interaction with --build: If you execute docker compose up --build --watch, Docker Compose will perform the initial build of your images before starting the services and initiating the watch process [3]. The --build flag ensures that your images are built from scratch before the containers are launched, and the --watch flag then attaches the file-monitoring logic to the running environment [1][3]. In summary, combining --build and --watch works as expected: it forces a fresh build of the services and then starts them with active file watching enabled. Note that docker compose watch is a separate command that also monitors build contexts and triggers rebuilds or refreshes, but it differs from up --watch primarily in how it handles log output and its initial startup behavior [1][4][5].
