About this tool

This tool parses a `docker run` command and emits an equivalent `docker-compose.yml` service definition. It maps the common flags — image, container name, published ports, volumes, environment variables, networks, restart policy, workdir, user, entrypoint, labels and command — to their Compose equivalents. The companion Docker Compose Builder (already in DevTools) goes the other direction visually. Use this when migrating one-off `docker run` invocations into a versioned Compose file. Parsing is client-side; no command is executed.

Examples & Use Cases

Web server with port mapping

# docker run command
docker run -d --name web -p 8080:80 nginx:latest

# docker-compose.yml
services:
  web:
    image: nginx:latest
    container_name: web
    ports:
      - "8080:80"

The container name becomes the service key; -p host:container maps to the ports list.

Database with env + volume

# docker run command
docker run -e POSTGRES_PASSWORD=secret -e POSTGRES_DB=app -v pgdata:/var/lib/postgresql/data postgres:15

# docker-compose.yml
services:
  postgres:
    image: postgres:15
    environment:
      POSTGRES_PASSWORD: secret
      POSTGRES_DB: app
    volumes:
      - pgdata:/var/lib/postgresql/data

Environment flags become a key/value map; named volumes map to the volumes list.

Restart policy + network

# docker run command
docker run --restart unless-stopped --network mynet redis:7

# docker-compose.yml
services:
  redis:
    image: redis:7
    networks:
      - mynet
    restart: unless-stopped

--restart maps to the restart field; --network maps to the networks list.

    About this tool

    Convert docker run commands to docker-compose.yml online. Free converter supporting ports, volumes, env, networks, restart policies — no signup, runs in your browser. Docker Run to Compose Converter runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

    What this tool does not do

    • Docker Run to Compose Converter is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.

    How do I use this tool?

    2D Fluid Dynamics & Particle Physics Sandbox

    A physics playground with two engines sharing one canvas. The fluid mode runs a real Eulerian Navier-Stokes solver — semi-Lagrangian advection, explicit diffusion, Jacobi pressure projection and vorticity confinement — that you paint with dye and velocity using mouse or touch. The particle mode is a damped Verlet N-body engine with gravity wells, Coulomb attractors and repulsors, spring links, wall restitution and elastic circle collisions. Particle counts adapt to the device (100k target on WebGL2 desktop, 2k-5k on CPU fallback), and every configuration exports as runnable code: a Matter.js world, a PixiJS ticker setup, or a standalone vanilla Canvas engine.

Every run shows the Big-O table and the phase-highlighted reference implementation in four languages, and compared values can be played as pitch (sonification) through the shared audio engine. Everything runs client-side; inputs never leave the browser.
