Generates a docker-compose yaml definition from a running container.
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 apache-test
Outputs a docker-compose compatible yaml structure:
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.
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>...
