Docker Run to Docker Compose Converter

What is a Docker Run to Docker Compose Converter?

Convert CLI <a href="https://docs.docker.com/" target="_blank" rel="noopener noreferrer" class="text-indigo-600 dark:text-indigo-400 font-semibold hover:underline" title="Learn more about Docker on official docs">docker</a> run commands into clean, valid `docker-compose.yml` configuration files. Automatically parses container names, port mappings (`-p`), environment variables (`-e`), volume mounts (`-v`), restart policies (`--restart`), and network flags.

Why Use This Tool?

  • Container Deployment Automation: Convert one-off CLI docker run commands into reusable docker-compose.yml scripts.
  • DevOps Migration: Migrate containerized development environments to docker-compose.
  • Prevent Flag Syntax Errors: Automatically convert volume mounts (`-v /host:/container`) and environment flags into clean YAML blocks.

How to Use

  1. Paste your `docker run` command line (e.g. `docker run -d -p 8080:80 -v /data:/app/data --name web nginx:latest`).
  2. Click Convert to Compose.
  3. Copy the generated `docker-compose.yml` file code.

Real Working Example

Input:

Docker Run: docker run -d --name my-redis -p 6379:6379 -v redis-data:/data --restart always redis:alpine

Output Result:

Docker Compose YAML:
version: "3.8"
services:
  my-redis:
    name: my-redis
    image: redis:alpine
    ports:
      - "6379:6379"
    volumes:
      - redis-data:/data
    restart: always

Important Technical Details & Specifications

  • Docker CLI Flag Parser Engine: Parses `-d`, `-p`, `-v`, `-e`, `--env-file`, `--name`, `--restart`, `--network`, `--link`, `-t`, and `-i`.
  • YAML 1.2 Formatter: Outputs valid Docker Compose v3 syntax formatted with 2-space indentation.
  • Local Memory Execution: Zero network overhead.

Is it free?

Yes, 100% free.

Are my docker commands sent to a server?
