An implementation of
docker-compose with podman backend. The main objective of this project is to be able to run
docker-compose.yml unmodified and rootless. This project is aimed to provide drop-in replacement for
docker-compose, and it's very useful for certain cases because:
- can run rootless
- only depend on
podmanand Python3 and PyYAML
- no daemon, no setup.
- can be used by developers to run single-machine containerized stacks using single familiar YAML file
For production-like single-machine containerized environment consider
For the real thing (multi-node clusters) check any production OpenShift/Kubernetes distribution like OKD.
This project is still underdevelopment.
Install latest stable version from PyPI:
pip3 install podman-compose
--user to install inside regular user home without being root.
Or latest development version from GitHub:
pip3 install https://github.com/containers/podman-compose/archive/devel.tar.gz
curl -o /usr/local/bin/podman-compose https://raw.githubusercontent.com/containers/podman-compose/devel/podman_compose.py chmod +x /usr/local/bin/podman-compose
curl -o ~/.local/bin/podman-compose https://raw.githubusercontent.com/containers/podman-compose/devel/podman_compose.py chmod +x ~/.local/bin/podman-compose
We have included fully functional sample stacks inside
A quick example would be
cd examples/busybox podman-compose --help podman-compose up --help podman-compose up
A more rich example can be found in examples/awx3 which have
- A Postgres Database
- RabbitMQ server
- MemCached server
- a django web server
- a django tasks
When testing the
AWX3 example, if you got errors just wait for db migrations to end.
tests/ directory we have many useless docker-compose stacks that are meant to test as much cases as we can to make sure we are compatible
How it works
The default mapping
1podfw creates a single pod and attach all containers to its network namespace so that all containers talk via localhost. For more information see docs/Mappings.md.
If you are running as root, you might use identity mapping.
