Docker Compose Production

What it does

This skill provides a production-ready Docker Compose template designed for deploying applications with security, reliability, and scalability best practices. It includes preconfigured services like Nginx, an API server, a worker process, and a PostgreSQL database, all set up with sensible defaults for a production environment. The template utilizes environment variables and secrets management to configure these services securely.

When to use it

• You're deploying a new application to a production environment and want a solid starting point.
• You need a standardized Docker Compose configuration across multiple production deployments.
• You require secure handling of database passwords and other sensitive information within your containerized applications.
• You are looking for a template that includes health checks, logging with size limits, resource reservations, and replica configurations.

Key capabilities

• Production-Ready Template: Provides a comprehensive base configuration for production deployments.
• Environment Variable Support: Allows customization of services through environment variables (e.g., API_VERSION, LOG_LEVEL).
• Secrets Management: Securely manages sensitive information like database passwords and JWT secrets using Docker secrets.
• Health Checks: Includes health check configurations for Nginx and the API service to monitor application availability.
• Logging with Size Limits: Configures logging drivers with options to limit log file size (e.g., max-size: "10m") and number of files (max-file: "3").
• Resource Management: Defines resource limits and reservations for CPU and memory for each service.
• Replication: Configures worker replicas for increased availability and scalability.

Example prompts

• "Deploy the production Docker Compose configuration."
• "Show me the default environment variables used in the Nginx service."
• "What secrets are required for the database container?"

Tips & gotchas

• This skill provides a template; you will need to customize it with your specific application code and configurations.
• Ensure that Docker secrets (db_password, jwt_secret) are properly configured in your environment before deployment.
• The API image uses $ { API_VERSION : - latest } which means the latest version of the image will be pulled from a registry, ensure this is desired behavior.
