12 Docker Development

Docker development spans the practices and workflows that make Docker genuinely productive for day-to-day software development — fast iteration loops, convenient local infrastructure, debugging tools, and effective integration with an editor or IDE — going beyond simply running an application in a container toward making that container-based workflow pleasant and efficient to actually work within.

Establishing a Fast Development Feedback Loop

Bind mounts combined with a hot-reloading development server provide the fast, iterative feedback loop developers expect, even while working within a containerized environment.

docker run -d -v $(pwd):/app -p 3000:3000 node:20-alpine npm run dev

Providing Convenient Local Supporting Infrastructure

Compose-defined databases, caches, and other dependencies give developers consistent, easily managed local infrastructure without requiring direct installation on their own machines.

services:
  db:
    image: postgres:16
    ports:
      - "5432:5432"

Debugging a Containerized Application Effectively

Direct access into a running container, combined with appropriate logging and debugging tool configuration, supports effective troubleshooting during development.

docker compose exec api sh
docker compose logs -f api

Integrating Docker With an Editor or IDE

Many editors and IDEs provide direct integration with Docker and Compose, allowing developers to manage containers, view logs, and even debug code running inside a container directly from their familiar development environment.

{
  "name": "Container Dev",
  "dockerComposeFile": "docker-compose.yml",
  "service": "api"
}

A configuration like this, supported by certain editors, can automatically open a development environment directly inside a running container.

Why Docker Development Matters

A genuinely productive Docker-based development workflow requires more than simply running an application in a container — thoughtful attention to feedback loops, local infrastructure, debugging access, and editor integration is what actually makes containerized development a pleasant, efficient experience rather than a cumbersome one.
