SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Simplifies building and debugging applications in Docker Compose by guiding developers to work with mounted source code and hot-reload workflows.

Core Features & Use Cases

  • Context-aware development: analyze docker-compose.yml to determine services, and identify mounted volumes that enable live code updates.
  • Structured development workflow: guidelines for code changes, selective rebuilds, in-container testing, and reliable troubleshooting.
  • Operational best practices: running tests inside containers, managing logs, and troubleshooting service startups.

Quick Start

Start the project with docker compose up -d and verify that changes to mounted code are reflected in the running services without a full rebuild.

Frequently Asked Questions about Docker Compose Development

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up Docker Compose hot-reload for local development?▼

You set up hot-reload by mounting local source code into service containers through volumes in docker-compose.yml. This allows live code updates in running services without requiring a full image rebuild for every change.

How do I run tests inside Docker Compose containers?▼

You run tests inside Docker Compose containers by executing test commands directly within the running service containers. This is part of a structured development workflow that ensures tests run in the same environment as the application.

What is the best way to troubleshoot service startup failures in Docker Compose?▼

The best way to troubleshoot Docker Compose service startup failures is by inspecting container logs. Analyzing the docker-compose.yml file helps determine service configurations, while log inspection isolates the root cause of startup issues.

When should I use selective rebuilds instead of a full Docker Compose rebuild?▼

Selective rebuilds are used when application dependencies change but source code does not. A structured development workflow uses mounted volumes for hot-reload during code changes, saving full rebuilds for dependency updates or Dockerfile modifications.

Why are my mounted volume changes not reflecting in the running Docker containers?▼

Mounted volume changes may not reflect if the docker-compose.yml volume paths are misconfigured or the application lacks a file watcher for hot-reload. Verifying the volume mounts and ensuring the service supports live reloading resolves this.
