docker-autocompose

Generates a docker-compose yaml definition from a running container.

Required Modules:

• pyaml
• docker

Example Usage:

sudo python autocompose.py <container-name-or-id>

Generate a compose file for multiple containers together:

sudo python autocompose.py apache-test mysql-test

The script defaults to outputting to compose file version 3, but use "-v 1" to output to version 1:

sudo python autocompose.py -v 1 apache-test

Outputs a docker-compose compatible yaml structure:

docker-compose reference

docker-compose yaml file specification

While experimenting with various docker containers from the Hub, I realized that I'd started several containers with complex options for volumes, ports, environment variables, etc. and there was no way I could remember all those commands without referencing the Hub page for each image if I needed to delete and re-create the container (for updates, or if something broke).

With this tool, I can easily generate docker-compose files for managing the containers that I've set up manually.

Docker Usage

You can use this tool from a docker container without installing it locally by either building it or using the automated build on dockerhub.

Build the container by running:

docker build -t red5d/docker-autocompose .

Use the new image to generate a docker-compose file from a running container or a list of space-separated container names or ids:

 docker run --rm -v /var/run/docker.sock:/var/run/docker.sock red5d/docker-autocompose <container-name-or-id> <additional-names-or-ids>...
