Docker Run to Docker Compose Converter — Free Online Compose Generator

Docker Run to Docker Compose Converter — Free Online Compose Generator. Convert docker run commands to a docker-compose.yml file online. Merge several containers into one Compose file, handle multi-line commands and named volumes — free and private.

Our free docker run to docker compose converter turns long command lines into a clean, ready-to-use docker-compose.yml in real time.

Paste a command such as docker run -d -p 5432:5432 -v pgdata:/var/lib/postgresql/data postgres:16 and the tool maps every flag it understands — ports, volumes, environment variables, networks, restart policies, logging options, labels, users, working directories and more — to the matching Compose keys.

It works like composerize, but goes further: you can convert docker run to compose for several containers at once, and they are merged into a single file with one service per command, so a database, a cache and a web server become one Compose stack you can start with docker compose up -d.

Real-world commands are rarely one tidy line, so the converter accepts multi-line commands with bash \, PowerShell backtick and cmd ^ continuations, strips $ prompts and sudo, and understands docker container run and podman run.

Named volumes such as pgdata are declared automatically in a top-level volumes: section and custom networks in networks:, which Compose requires.

Options let you use each container's --name as the service key, switch between 2- and 4-space indentation and add the legacy version: key for old Compose v1 installs (modern Docker Compose ignores it).

Flags that have no Compose equivalent, such as --rm or -d, are listed clearly instead of being silently dropped. To validate or reformat the result, open it in our YAML Viewer or convert it with the YAML to JSON Converter.

This docker compose generator runs entirely in your browser: commands that contain passwords, API keys or internal hostnames are never sent to a server.

Load one of the examples to see how it works, copy the YAML or download it as docker-compose.yml, and share a link that restores your commands and options for teammates.

Frequently asked questions

How do I convert a docker run command to docker compose?

Paste the command, for example docker run -d -p 80:80 --name web nginx, into Docker run command(s). The docker-compose.yml is generated as you type; click Copy to clipboard or Download docker-compose.yml, then start it with docker compose up -d.

Can I combine several containers into one Compose file?

Yes. Put each docker run command on its own line or chain them with &&. Every command becomes a separate service in the same file, and named volumes used by the services are declared in a top-level volumes section.

Does it handle multi-line docker run commands?

Yes. Line continuations with a backslash (bash), backtick (PowerShell) or caret (cmd) are joined, a leading $ prompt and sudo are removed, and docker container run and podman run are treated like docker run.

Why are some docker run options not converted?

Some flags, such as --rm, have no Compose equivalent, and a few are not implemented by the underlying composerize converter. They are listed in the boxes under the output so you can handle them by hand; lines that are not docker run commands are listed separately.

Does my docker-compose.yml need a version key?

No. The version key is obsolete in the Compose Specification and Docker Compose v2 ignores it, so it is left out by default. Switch on Add legacy version key only if an older tool requires it; it adds version 3.9.

How are the services named?

By default the service name comes from the image, for example nginx. Turn on Use --name as service name to use the container name instead. If two services would get the same name, the later one is renamed so every name is unique.

Practical tips

Before copying the final result, check important details such as spacing, casing, filenames, encoding, token structure, line breaks, or output format. Small checks prevent mistakes when the result is reused in source code, API requests, documentation, spreadsheets, or shared files.
