Generate Docker Components

Generate Docker configuration components for PHP projects with production-ready defaults.

Input Parsing

Parse $ARGUMENTS to extract component type, optional name, and meta-instructions:

Format: <component-type> [name] [-- <meta-instructions>]

Examples:
- /acc:generate-docker dockerfile
- /acc:generate-docker compose
- /acc:generate-docker full
- /acc:generate-docker dockerfile production -- with Symfony
- /acc:generate-docker compose myapp -- with PostgreSQL and Redis
- /acc:generate-docker nginx -- with SSL termination
- /acc:generate-docker entrypoint -- with migrations

Parsing rules:

1. First part = component type (required, see list below)
2. Second part = name (optional project/service name)
3. After -- = meta-instructions (optional customizations)

Supported Components

Component	Aliases	Description
dockerfile	df	Production multi-stage Dockerfile
compose	dc, docker-compose	Docker Compose configuration
nginx	web	Nginx reverse proxy config
entrypoint	ep, entry	Container entrypoint script
makefile	mk, make	Docker Makefile commands
env	environment	Environment variable template
healthcheck	hc, health	Health check script
full	all, stack	Complete Docker setup

Pre-flight Check

1. Verify valid component type:

   • If not provided, ask user which component to generate
   • If invalid, show list of supported components

2. Check project structure:

   # PHP project info
   cat composer.json 2>/dev/null
   
   # Detect framework
   grep -E "(symfony|laravel)" composer.json 2>/dev/null
   
   # Check existing Docker files
   ls Dockerfile* docker-compose* .dockerignore 2>/dev/null
   
   # Check project directories
   ls -d src/ app/ public/ config/ 2>/dev/null
   

3. Detect framework and services:

   • Symfony: symfony/framework-bundle in composer.json
   • Laravel: laravel/framework in composer.json
   • MySQL: doctrine/dbal or ext-pdo_mysql
   • PostgreSQL: ext-pdo_pgsql
   • Redis: predis/predis or ext-redis
   • RabbitMQ: php-amqplib/php-amqplib or ext-amqp

Instructions

Use the acc:docker-coordinator agent to generate components:

Task tool with subagent_type="acc:docker-coordinator"
prompt: "Generate Docker component: [COMPONENT_TYPE]

Operation: GENERATE
Component: [COMPONENT_TYPE]
Name: [NAME if provided]

Project info:
- PHP version: [from composer.json]
- Framework: [detected framework]
- Extensions: [from composer.json require]
- Services: [detected services]

[META-INSTRUCTIONS if provided]

Requirements:
1. PHP 8.4 with Alpine base
2. Multi-stage builds for Dockerfile
3. Health checks for all services
4. Non-root user
5. BuildKit optimizations
6. Production-ready defaults
7. Follow existing project patterns"

Generation Examples

Dockerfile

/acc:generate-docker dockerfile
/acc:generate-docker df -- with Symfony and PostgreSQL

Generates:

Dockerfile              # Production multi-stage build
Dockerfile.dev          # Development with Xdebug
.dockerignore           # Build context exclusions

Docker Compose

/acc:generate-docker compose
/acc:generate-docker dc -- with MySQL, Redis, RabbitMQ

Generates:

docker-compose.yml      # Development stack
docker-compose.prod.yml # Production overrides
.env.docker             # Environment template

Nginx

/acc:generate-docker nginx
/acc:generate-docker web -- with SSL and rate limiting

Generates:

docker/nginx/nginx.conf    # Main config
docker/nginx/default.conf  # Server block

Entrypoint

/acc:generate-docker entrypoint
/acc:generate-docker ep -- with migrations and cache warmup

Generates:

docker/entrypoint.sh    # Startup script with signal handling

Makefile

/acc:generate-docker makefile
/acc:generate-docker mk -- with deploy targets

Generates:

Makefile.docker         # Docker commands (or appends to existing Makefile)

Environment

/acc:generate-docker env
/acc:generate-docker environment -- with all services

Generates:

.env.docker             # Environment template with documentation

Health Check

/acc:generate-docker healthcheck
/acc:generate-docker hc -- for PHP-FPM and custom endpoint

Generates:

docker/healthcheck.sh   # Health check script

Full Stack

/acc:generate-docker full
/acc:generate-docker all -- Symfony with PostgreSQL, Redis, RabbitMQ

Generates:

Dockerfile              # Production multi-stage
Dockerfile.dev          # Development with Xdebug
.dockerignore           # Context exclusions
docker-compose.yml      # Development stack
docker-compose.prod.yml # Production overrides
.env.docker             # Environment template
