Docker-Compose with RancherOS

I was trying to get SonarQube test instance for my HomeLab, and found out Bitnami docker image (link). I thought about using my RancherOS freshly updated VM for trying to run it.

The first obstacle happened to be the curl. There is no curl installed on bare RancherOS instance. But there is wget so a simple fix to replace those commands.

The second problem was bigger, you get docker-compose.yml file, and have to run docker-compose to start the stack. But there is no docker-compose on RancherOS...

After searching the web I discovered there is a docker image with docker compose, but no instructions on how to execute it from container.

After some googling I crafted a woring command:

docker run --rm -it -v ${PWD}:/tmp -v /var/run/docker.sock:/var/run/docker.sock -w /tmp docker/compose up

• -v ${PWD}:/tmp mounts the current directory as /tmp on docker container
• -v /var/run/docker.sock:/var/run/docker.sock allows docker-compose to talk to rancherOS docker
• -w /tmp sets the working directory for docker container
• docker/compose is the latest compose image
• up is the command

Overall it's the equivalent of running docker-compose up but without having docker-compose installed/available.
