Docker Extend

Sets up personal Docker tool customization using the project's gitignored override pattern. Your Dockerfile.user and docker-compose.override.yml are yours — never committed to git.

Step 1: Detect Context

Determine if the user is in dev (source build) or deploy (GHCR) mode:

!if [ -f docker-compose.yml ] && grep -q 'build: \.' docker-compose.yml 2>/dev/null; then echo "DEV_MODE: Building from source (root docker-compose.yml)"; elif [ -f deploy/docker-compose.yml ]; then echo "DEPLOY_MODE: Using GHCR image (deploy/docker-compose.yml)"; else echo "UNKNOWN_MODE: No docker-compose.yml found in root or deploy/"; fi

Decision:

• DEV_MODE → work with Dockerfile.user + docker-compose.override.yml (repo root)
• DEPLOY_MODE → work with deploy/Dockerfile.user + deploy/docker-compose.override.yml
• UNKNOWN_MODE → ask the user which directory their docker-compose.yml lives in before proceeding

Step 2: Check Current State

DEV_MODE — check root files:

!echo "=== Dockerfile.user ===" && (cat Dockerfile.user 2>/dev/null || echo "(not found — will create from example)") && echo "" && echo "=== docker-compose.override.yml ===" && (cat docker-compose.override.yml 2>/dev/null || echo "(not found — will create from example)")

DEPLOY_MODE — check deploy/ files:

!echo "=== deploy/Dockerfile.user ===" && (cat deploy/Dockerfile.user 2>/dev/null || echo "(not found — will create from example)") && echo "" && echo "=== deploy/docker-compose.override.yml ===" && (cat deploy/docker-compose.override.yml 2>/dev/null || echo "(not found — will create from example)")

If both files already exist: Skip to Step 4 (add tools). If files are missing: Proceed to Step 3 (copy from examples). If example files are missing too: Tell the user the project hasn't added the example files yet and to check with the maintainers or the docs.

Step 3: Copy Example Files

Run only the copy commands for whichever files are missing. Do NOT overwrite existing files.

DEV_MODE:

# Only if Dockerfile.user does not exist:
cp Dockerfile.user.example Dockerfile.user

# Only if docker-compose.override.yml does not exist:
cp docker-compose.override.example.yml docker-compose.override.yml

DEPLOY_MODE:

# Only if deploy/Dockerfile.user does not exist:
cp deploy/Dockerfile.user.example deploy/Dockerfile.user

# Only if deploy/docker-compose.override.yml does not exist:
cp deploy/docker-compose.override.example.yml deploy/docker-compose.override.yml

After running the copy commands, confirm to the user which files were created.

Step 4: Add Tools

Parse $ARGUMENTS for tool names (space-separated, e.g., vim ripgrep jq).

If tools were specified: Edit the appropriate Dockerfile.user to add (or uncomment) the RUN apt-get install block with the requested packages. Use the Edit tool — do not rewrite the entire file.

The block to add/modify:

RUN apt-get update && apt-get install -y --no-install-recommends \
    <tool1> \
    <tool2> \
 && rm -rf /var/lib/apt/lists/*

If no tools were specified: Show the user the file and ask which tools they want to add. Then edit the file accordingly.

Step 5: Rebuild

Show the user the rebuild command for their context. Do NOT run it automatically.

DEV_MODE:

docker compose build && docker compose up -d

DEPLOY_MODE:

cd deploy && docker compose build && docker compose up -d

Summary

Tell the user:

1. Which files were created (if any)
2. Which tools were added to Dockerfile.user (if any)
3. The rebuild command to run when ready
4. A reminder that Dockerfile.user and docker-compose.override.yml are gitignored — they're personal and won't be committed
