How to convert a docker run command to Compose

  1. 01

    Paste the docker run command

    For literal POSIX shell commands targeting Linux containers. Maximum 64 KiB UTF-8. Raw env files require Compose 2.30+. This is a configuration draft; no shell, Docker daemon or image is executed or inspected. Use one literal docker run command. Replace host variables with explicit values; quote literal $ in single quotes or escape it. Shell expansion, pipes, redirects, command substitution and unescaped line breaks are not supported. Backslash line continuation is supported.

  2. 02

    Convert to a Compose service

    Convert name, ports, explicit environment values, raw env files, mounts, restart, network, workdir, user, entrypoint and labels. -i/-t (including -it) become stdin_open/tty. Short options accept attached values and long options accept =value. Unknown options stop conversion.

  3. 03

    Check the generated YAML

    Arguments after the image retain their order and empty strings in the command list. A nonempty entrypoint stays one argument; an empty entrypoint clears it. Literal dollar signs are doubled for Compose, preserving their value instead of interpolating the host environment. The default network is explicitly bridge. Bind mounts keep the difference between -v (may create a host directory) and --mount (must exist).

  4. 04

    Review the unsupported list

    An option is not supported. No partial YAML was generated. Use the supported options listed in the guide; move container command arguments after the image. --rm is not represented in YAML. Choose the appropriate Compose run/removal lifecycle yourself. -d/--detach is a launch option: use docker compose up -d when appropriate.

  5. 05

    Copy or download the YAML

    env_file uses raw format (Compose 2.30+) to preserve dollar signs and quotes. Relative paths resolve beside compose.yaml. File contents and unset variables are not inspected; review the actual environment. Named volumes and custom networks are external references with their original names. They must already exist before launch; no resources are created or checked here.

What Docker Run to Compose actually does

A deployment note from a teammate is one long docker run line — docker run -d --name web -p 8080:80 -e NODE_ENV=production -v /srv/data:/data:ro --restart unless-stopped nginx:1.27-alpine — and the project standard is Compose; a forum answer holds exactly the flags you need but not as YAML; a legacy script's container options have to be audited before they move into version control. Pasting that line yields a web service with its port mapping, environment, read-only volume, and restart policy laid out for review, while -d is flagged as lifecycle-only instead of being dropped. Docker Run to Compose turns the command into one reviewable service in the browser — without contacting a daemon, a registry, or Docker itself.

Common questions

Which docker run flags are converted?
Unsupported or conflicting mount. Use -v source:/target[:ro|rw] or /target, or --mount with type=bind|volume, source/src, target/destination/dst, readonly/ro=true|false and volume-nocopy=true|false for volumes. Other fields and duplicate targets are rejected.
Why are --rm and -d listed as unsupported?
--rm is not represented in YAML.
How is the Compose service named?
The service name comes from --name when present, otherwise from the image reference with its registry path and tag removed: registry.example.com/team/nginx:1.27 becomes nginx. Characters outside lowercase letters, digits, underscores, and hyphens collapse to hyphens, and an empty result falls back to app. container_name is only emitted when --name was given explicitly.
What happens to the arguments after the image?
Arguments after the image retain their order and empty strings in the command list.
Is the generated YAML ready for production?
Maximum 64 KiB UTF-8.
Is my command uploaded anywhere?
No. Parsing and conversion run entirely inside the current browser tab, the command is never sent or retained, and no account is required.
