Docker Compose builder

Build a Docker Compose file with a form for services, ports, volumes, environment variables and networks.

Services

Image

Required unless a build context or dockerfile is set. Image and build may be used together.

Try:

Service name

Container name

Build context

Dockerfile

Restart policy

Hostname

Working directory

User

Ports

One per line. A single container port is also allowed.

Expose

Optional container ports, one per line.

Volumes

One short-syntax mount per line. Undeclared named volumes are declared automatically.

No environment variables.

Environment files

Command

Emitted as a string. Imported lists are shell-joined; quoting is best-effort.

Entrypoint

Emitted as a string. Imported lists are shell-joined; quoting is best-effort.

Add another service to declare dependencies.

Networks

Declare networks in the Project section, then select them here.

Additional service YAML

A mapping for other Compose keys. Keys managed by the form cannot be repeated here.

Project name (optional)

No declared volumes.

No declared networks.

Additional top-level YAML

Advanced top-level keys such as secrets and configs. Do not repeat name, services, volumes or networks.

Import compose.yaml

Existing compose.yaml

Single-document YAML only. Import replaces the form only after the whole file validates.

Command and entrypoint lists are shell-joined on import; quoting is best-effort. Unrecognized keys are kept in the additional YAML fields.

compose.yaml

Service "web": Set an image or a build context/dockerfile.

Compose interpolates $VARIABLE; use $$ for a literal dollar sign. This file is generated locally in your browser.
