# docker-autocompose
|
|
Generates a docker-compose yaml definition from a docker container.
|
|
|
|
Required Modules:
|
|
* [pyaml](https://pypi.python.org/project/pyaml/)
|
|
* [docker](https://pypi.python.org/project/docker)
|
|
* [six](https://pypi.python.org/project/six)
|
|
|
|
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:

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 by either cloning this repo and building the image or using the [automatically generated image on GitHub](https://github.com/Red5d/docker-autocompose/pkgs/container/docker-autocompose)
|
|
|
|
Pull the image from GitHub (supports both x86 and ARM)
|
|
|
|
docker pull ghcr.io/red5d/docker-autocompose:latest
|
|
|
|
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 ghcr.io/red5d/docker-autocompose <container-name-or-id> <additional-names-or-ids>...
|
|
|
|
To print out all containers in a docker-compose format:
|
|
|
|
docker run --rm -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/red5d/docker-autocompose $(docker ps -aq)
