Prompt

I'm building a multi-container application with a React frontend, Python FastAPI backend, MongoDB database, and Redis cache. I need a complete local and production container orchestration setup. Please generate the primary configuration file along with development and production override files, a template for environment variables, custom Dockerfiles where needed, and simple bash scripts for starting, stopping, and viewing logs.

What was checked, without and with the skill

Generating Docker Compose Files

Overview

Generate production-ready docker-compose.yml files for multi-container applications. Define services, networks, volumes, health checks, resource limits, and environment-specific overrides for local development, testing, and single-host production deployments.

Prerequisites

Docker Engine 20.10+ and Docker Compose v2 (docker compose version)
Application Dockerfiles for each service or pre-built images available
Understanding of service dependencies and inter-service communication ports
Environment variable values or .env files for configuration
Sufficient disk space and memory for all containers defined in the stack

Instructions

Scan the project for existing Dockerfiles, docker-compose*.yml files, and application entry points
Identify all services that compose the application stack (web server, API, database, cache, message queue, worker)
Define each service with image or build context, port mappings, and environment variables
Configure service dependencies using depends_on with health check conditions to ensure proper startup order
Create named volumes for persistent data (database files, uploads, cache) and bind mounts for development hot-reload
Define custom bridge networks to isolate service groups (frontend, backend, data tier)
Add health checks for each service to enable dependency-aware startup and container orchestrator integration
Set resource limits (deploy.resources.limits) for CPU and memory to prevent a single container from exhausting the host
Create environment-specific override files: docker-compose.override.yml for development, docker-compose.prod.yml for production
Validate the configuration with docker compose config to check for syntax errors

Output

docker-compose.yml with service definitions, networks, and volumes
Environment-specific override files (docker-compose.override.yml, docker-compose.prod.yml)
.env file template with documented variables
Dockerfiles for services that require custom builds
Helper scripts for common operations (start.sh, stop.sh, logs.sh)

Error Handling

Error	Cause	Solution
`port is already allocated`	Another container or host process using the same port	Change the host port mapping or stop the conflicting process
