Summary

Implements #202 - Add Docker support for local development and deployment

This PR adds a complete Docker setup that allows running the entire LaraBlog application with a single docker compose up -d command.

Changes

Docker Services

• app: PHP 8.2 FPM with Laravel application
• nginx: Alpine-based web server
• mysql: MySQL 8.4 with health checks
• redis: Redis 7 for caching and sessions
• mailpit: Email testing tool (replaces Mailhog)

Key Features

Production Ready:
✅ Single command deployment: docker compose up -d
✅ Automatic database migrations on startup
✅ Cache optimization (config, routes, views)
✅ Queue workers with Supervisor auto-restart
✅ Task scheduler included
✅ Health checks for service dependencies
✅ Persistent volumes for data
✅ OPcache enabled for performance

Development Friendly:
✅ Hot-reload via volume mounting
✅ One-command setup: ./docker-setup.sh
✅ Makefile shortcuts (make up, make logs, etc.)
✅ Mailpit UI at localhost:8025
✅ Easy container and log access
✅ Local environment preconfigured

Lightweight & Secure:
✅ Alpine Linux base images
✅ Latest stable versions (PHP 8.2, MySQL 8.4, Redis 7)
✅ Multi-stage Docker builds
✅ Minimal attack surface
✅ Secure production defaults

Files Added

• Dockerfile - Multi-stage build for dev/prod
• docker-compose.yml - Service orchestration
• docker-setup.sh - Automated setup script
• Makefile - 20+ convenience commands
• DOCKER.md - Comprehensive documentation
• DOCKER-QUICKREF.md - Quick reference card

Quick Start

For Local Development

./docker-setup.sh
# Access: http://localhost
# Mailpit: http://localhost:8025

For Production

cp .env.docker .env
# Edit .env with production values
docker compose up -d

Testing

Tested with Docker Compose v2. All services start correctly with proper health checks and dependencies.

Documentation

• Full guide: DOCKER.md
• Quick reference: DOCKER-QUICKREF.md
• Makefile commands: make help

Migration Notes

• No breaking changes to existing setup
• Docker is completely optional
• Traditional installation still works
• Can be deployed alongside existing infrastructure

Closes #202

Pull request overview

Adds a full Docker + Docker Compose setup to run LaraBlog locally (and intended for production), along with helper scripts and documentation to streamline environment setup.

Changes:

• Introduces multi-service docker-compose.yml (app/nginx/mysql/redis/mailpit) plus Dockerfile build stages.
• Adds operational glue: entrypoint script, Supervisor config (queue worker + scheduler), PHP/Nginx/MySQL tuning.
• Adds developer UX: docker-setup.sh, Makefile shortcuts, and Docker documentation/quick reference; README updated with Docker install path.

build.target is derived from APP_ENV, but the Dockerfile stages are named development and production. With .env set to APP_ENV=local (as docker-setup.sh does), docker compose build will try to build a non-existent local stage and fail. Use a separate variable (e.g., DOCKER_TARGET) or align APP_ENV values/stage names so development builds select the development stage.

Suggested change

	target: ${APP_ENV:-production}
	target: ${DOCKER_TARGET:-production}

[Copilot]

The app service bind-mounts the entire project (./:/var/www/html). In production this overrides everything baked into the image (vendor/, built Vite assets, cached config), which can break the “production-ready” flow and negates the multi-stage build. Consider moving bind mounts to a docker-compose.override.yml for local dev, and in production mount only persistent paths (e.g., storage/) via named volumes.

[Copilot]

Using axllent/mailpit:latest makes environments non-reproducible (updates to latest can break builds unexpectedly). For production readiness, pin to a specific Mailpit version tag and bump intentionally.

Suggested change

	image: axllent/mailpit:latest
	image: axllent/mailpit:v1.20.5

[Copilot]

opcache.validate_timestamps=0 disables PHP file change detection, which will make hot-reload / bind-mounted code changes not take effect without restarting PHP-FPM. Since this config is copied into the shared base stage, it impacts development too. Consider using a separate OPcache config for dev (validate_timestamps=1) vs prod, or conditionally enabling OPcache based on environment.

Suggested change

	opcache.validate_timestamps=0
	opcache.validate_timestamps=1

[Copilot]

The production stage is FROM base, and base installs build-time tools like git/nodejs/npm. This contradicts the stated goal of a lightweight/minimal-attack-surface production image and increases image size and CVE surface. Consider a true multi-stage approach: build assets/deps in a builder stage, then copy only vendor/ + built assets into a slim runtime stage without node/npm/git.

[Copilot]

The MySQL wait loop has no timeout and will block container startup indefinitely if credentials are wrong or the DB never becomes reachable. For more predictable behavior (especially in production), add a max retry/timeout and exit non-zero so orchestrators can surface a clear failure and restart/backoff appropriately.

Suggested change

	until php artisan db:show > /dev/null 2>&1; do
	echo "MySQL is unavailable - sleeping"
	sleep 2
	MYSQL_MAX_RETRIES="${MYSQL_MAX_RETRIES:-30}"
	MYSQL_RETRY_INTERVAL="${MYSQL_RETRY_INTERVAL:-2}"
	attempt=1
	until php artisan db:show > /dev/null 2>&1; do
	if [ "$attempt" -ge "$MYSQL_MAX_RETRIES" ]; then
	echo "MySQL is unavailable after $attempt attempts - exiting"
	exit 1
	fi
	echo "MySQL is unavailable - sleeping (${attempt}/${MYSQL_MAX_RETRIES})"
	attempt=$((attempt + 1))
	sleep "$MYSQL_RETRY_INTERVAL"

supervisord is configured to run as root and the queue worker / scheduler programs don’t override user=..., so those long-running artisan processes will run as root. This is both a security concern and can create root-owned files in bind-mounted volumes (leading to permission issues on the host). Consider running supervisor and/or the artisan programs as www-data (or a dedicated non-root user) and only keeping root where strictly required.

COPY . . happens before dependency installation, so any change in the repo invalidates the Docker cache and forces a full composer install + npm ci rebuild. To speed up rebuilds, copy composer.json/composer.lock and package*.json separately, install deps, then copy the rest of the source.

Suggested change

	# Copy application files
	COPY . .
	# Install PHP dependencies
	RUN composer install --no-dev --optimize-autoloader --no-interaction --prefer-dist
	# Install Node dependencies and build assets
	RUN npm ci && npm run build && rm -rf node_modules
	# Copy dependency manifests first to maximize Docker cache reuse
	COPY composer.json composer.lock ./
	COPY package*.json ./
	# Install PHP dependencies
	RUN composer install --no-dev --optimize-autoloader --no-interaction --prefer-dist
	# Install Node dependencies
	RUN npm ci
	# Copy application files
	COPY . .
	# Build assets after the source is available, then clean up Node modules
	RUN npm run build && rm -rf node_modules

The MySQL service publishes port 3306 to the host by default. For production deployments this is usually unnecessary and weakens the “secure defaults” story (it exposes the DB to anything that can reach the host). Consider removing the ports: mapping (Compose network access is enough) or gating it behind a dev-only override file/profile.

Suggested change

	ports:
	- "${DB_PORT:-3306}:3306"

[Copilot]

The Redis service publishes port 6379 to the host by default. That’s convenient for local dev, but for production it increases exposure without authentication/TLS. Consider removing the host port mapping or making it dev-only (e.g., via override file/profile), relying on internal Compose networking instead.

Suggested change

	ports:
	- "${REDIS_PORT:-6379}:6379"

Merge conflicts resolved in commit 864a4b3. The only conflict was in package-lock.json — the PR branch uses newer package versions (Tailwind v4, Vite v7) that already supersede the security patches merged into main, so the PR branch's lock file was retained.
