Error Starting Project using Podman

Hi, I use podman as docker replacement and I was not able to start the project using ./manage start --logs. I was able to solve the problem and it seems to be an intended incompatibility between docker and podman. So it might not to be a bug of this project. However, I still wanted to leave this here for others that might run into the same problem.

Problem:

All container exited because DOCKERHOST is missing

DOCKERHOST resolution:

The problem is that the used DOCKERHOST resolution does not work with podman. Neither host.docker.internal nor docker run --rm --net=host eclipse/che-ip returns the docker host IP. (from used script: https://raw.githubusercontent.com/bcgov/DITP-DevOps/main/code/snippets/getDockerHost) This seems to be intended by the podman devs: https://github.com/containers/podman/issues/10878

Solution

The default IP for podman seems to be 10.0.2.2. Setting the DOCKERHOST=10.0.2.2 in the .env file solved this issue.

EDIT:

This solution made the webserver work but the webserver was not able to connect to the pool.
Uninstalling podman and switching to docker solved this and now everything works.
So there are probably more incompatibilities with podman.
