Convert docker run commands into clean docker-compose.yml specifications
About Docker Run to Compose Converter
How Docker Run to Compose Converter Works
Lexically parses and tokenizes single-line or multi-line docker run shell commands, extracting ports (-p), volumes (-v), environment variables (-e), network configurations, restart policies, and entrypoints into standardized Compose Specification YAML client-side with zero network transmission.
Docker Run to Docker Compose Converter is a DevOps and containerization utility for migrating ephemeral CLI docker run commands into maintainable, version-controlled docker-compose.yml configuration files. It translates complex container flags—including host-to-container port mappings (-p), named and bind volume mounts (-v), environment variable declarations (-e) and env-files, custom network configurations, restart policies, entrypoint overrides, health checks, resource limits, and commands—into standardized YAML compliant with the Compose Specification and Compose v3.8. Designed for infrastructure engineers, backend developers, and self-hosters managing servers with Portainer, Docker Compose, or Unraid, it runs 100% on-device so sensitive passwords, API keys, and internal IP addresses never leak.
Frequently asked questions
Why convert docker run commands into docker-compose.yml?+
Docker run commands are hard to maintain, easy to lose from shell history, and tedious to modify when adding new ports or volume mounts. A docker-compose.yml file provides a single declarative source of truth that can be version-controlled in Git, shared across teams, and launched with a simple 'docker compose up -d'.
How are sensitive environment variables and credentials handled?+
The entire parsing and YAML generation workflow executes 100% locally in your browser's memory. Secret keys, database passwords (like POSTGRES_PASSWORD), and internal hostnames are never uploaded to any remote server or logged in external databases.
Does this tool support multi-line commands with backslashes?+
Yes. The parser effortlessly handles bash backslash (\) and PowerShell backtick (`) line continuation characters, as well as single and double-quoted argument values with spaces.
What is the difference between Compose v3.8 and Compose Specification?+
Earlier versions of Docker Compose required a top-level 'version: "3.8"' attribute. The modern Docker Compose Specification (v2+) considers the version attribute obsolete and infers features dynamically. You can toggle the version header on or off depending on your deployment environment.
Can I convert multiple docker run commands?+
You can convert each container command individually and easily merge service blocks into a single multi-service docker-compose.yml.
Limitations
Some proprietary or hypervisor-specific flags (such as GPU nvidia-container-runtime parameters or complex cgroup configurations) may require manual adjustments for advanced orchestration clusters.
