Add Postgres, Valkey, MinIO, Caddy, release, and bundled web services
to the compose stack. Make local development and CI use the same cache,
media, and static storage backends, then refactor the Dockerfile into base
and prod stages for the production-shaped services.

Summary by CodeRabbit

  • New Features

    • Added Redis/Valkey-backed caching and session support.
    • Added MinIO/S3-compatible storage for media and static files.
    • Added CDN-style delivery for static assets through a reverse proxy.
    • Improved production database security and connection handling.
  • Infrastructure

    • Standardized local development, CI, and production environments with Docker Compose.
    • Added automated storage-bucket initialization and static-asset delivery.
    • Streamlined production container builds and dependency installation.
  • Documentation

    • Updated development, data-management, database, and deployment workflows for Docker Compose and ECS.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR standardizes local development, CI, and operational workflows on Docker Compose. It adds PostgreSQL, Valkey, MinIO, Caddy, production image stages, shared Django settings helpers, S3-backed storage, Redis caching, and Compose-based application tasks.

Changes

Compose Runtime

Layer / File(s) Summary
Shared settings and environment contracts
.env.example, tcf_core/settings/*.py
Shared settings define PostgreSQL environment lookup, Redis caching, S3 storage, sessions, and Cachalot. Development settings use Valkey and MinIO. Production settings add PostgreSQL SSL and connection settings.
Container images and Compose services
Dockerfile, docker-compose.yml, Caddyfile, .dockerignore
The image uses base and prod stages. Compose adds PostgreSQL, Valkey, MinIO, bucket initialization, Caddy, release, and production web services.
CI Compose test execution
.github/workflows/ci.yml
CI writes Compose environment values, starts services, initializes MinIO, runs migrations and tests in the web container, reports coverage, and removes the stack.
Compose database and command workflows
scripts/hide_review.sh, scripts/local_dump.sh, scripts/reset-db.sh
Management commands and database dump and restore workflows now use Docker Compose services.
Compose development and operations documentation
doc/dev.md, doc/grade-data.md, doc/semester-data.md, doc/useful-commands.md
Documentation describes Compose setup, service modes, management commands, database workflows, ECS tasks, and the deprecated semester-data guide.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to c026f

This PR reshapes local and CI execution around a production-like Compose stack, but the current version can prevent the application from starting, allow failed migrations or tests to pass CI, and connect to an unverified production database server. These issues create merge-blocking runtime, reliability, and security risk until fixed or explicitly accepted.

Run the production process as a non-root user and exclude .env from the image.

The base image runs as root, and scripts/container-startup.sh directly starts Gunicorn. Create an application user, assign file ownership, and set USER before CMD.

The CI workflow creates .env before building the prod image. COPY . /app/ includes that file because .dockerignore does not exclude it. Add .env and other credential files to .dockerignore, and inject secrets at runtime.

🌐 Web query:

official minio/mc Docker image Dockerfile scratch sh entrypoint latest

💡 Result:

The official Dockerfile for the minio/mc image, as maintained in the primary GitHub repository, uses scratch as its base image [1][2][3]. Because the resulting image is based on scratch—which contains no shell or utilities—you cannot run /bin/sh directly within the standard minio/mc container [1][3]. Key technical details: 1. Base Image: The official Dockerfile builds the binary using a golang-alpine image, then copies the resulting binary and necessary CA certificates into a scratch image [1][3]. 2. Entrypoint: The Dockerfile explicitly sets the ENTRYPOINT to ["mc"] [1][3]. 3. Shell Access: Since the image is based on scratch, it does not include a shell. If you need to access a shell within a MinIO client container for troubleshooting or configuration, you must either override the entrypoint to a shell (if the shell exists in the image, though this will not work with the standard scratch-based image) or use a different approach [4][5]. 4. Overriding Entrypoint: Official documentation notes that to use the container in environments like GitLab CI, you must set the entrypoint to an empty string (e.g., entrypoint: ['']) to allow the execution of custom commands [4][5][6]. If you specifically require a shell, you might need to use a different base image or a custom-built image, as the standard official production image lacks this capability by design [1][3]. Note: There are alternative Dockerfiles in the repository, such as Dockerfile.release, which utilize UBI-micro images instead of scratch [7], but the primary Dockerfile defaults to scratch [1][3].

Citations:


Use an init image that includes sh.

minio/mc:latest is based on scratch and includes only mc. The sh -c entrypoint at docker-compose.yml:67 can therefore fail before bucket creation. release and web remain blocked because they require successful completion of minio-init.

Use a shell-capable image or replace the shell chain with supported mc commands.

Start the full Compose profile before using exec web.

docker compose up in doc/dev.md starts only the unprofiled services. web is added by the full profile. If a developer follows that default command, this exec command fails because web is not running. State the full-profile startup command here, or use docker compose --profile full run --rm web ... for a one-off load. Remove the $ prompt unless output is shown; markdownlint MD014 flags this command block.

Document the exact ECS invocation.

scripts/ecs-run-command.sh expects <command> [args...], but this paragraph only names the helper. Add the command that operators must run, such as ./scripts/ecs-run-command.sh python manage.py load_grades ALL_DANGEROUS.

Proposed documentation update
-For production, run the management command as a one-off ECS task with
-`scripts/ecs-run-command.sh`; do not add it to the web container startup.
+For production, run:
+
+```console
+./scripts/ecs-run-command.sh python manage.py load_grades ALL_DANGEROUS
+```
+
+Do not add the command to the web container startup.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep reviews as a QuerySet before calling order_by.

list(...) converts reviews to a Python list. Line [46] then calls reviews.order_by, which raises AttributeError. Convert to a list only after ordering and slicing.

Proposed fix
-reviews = list(Review.objects.filter(text__icontains="<review drive tag>"))
+reviews = Review.objects.filter(text__icontains="<review drive tag>")
 total_winners = 3
-winners = reviews.order_by("?")[:total_winners]
+winners = list(reviews.order_by("?")[:total_winners])

Keep the dump output inside db/.

dump_path accepts path traversal. For example, ../README.md passes the directory check because db/../README.md has an existing parent, then > truncates that file and writes a database dump. Reject path separators or resolve the path and verify that it remains below db/.

Proposed fix
 filename="${1:-local.dump}"
