Error Starting Project using Podman

[TomAtGithub]

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

von-webserver-1 exited with code 1

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: containers/podman#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.
