podman support for commands test

[parul1593]

Is there a plan to support podman/buildah for doing command test in container structure test. As for doing command test today, it needs docker today.

[donmccasland]

No current plans. But we are accepting designs and code changes.

Hey, I just wanted to chime in and say that as of Podman 3.0 this use-case is partially supported!

$ systemctl start --user podman.socket # make sure podman socket is available
$ export DOCKER_HOST="unix://$XDG_RUNTIME_DIR/podman/podman.sock"
$ container-structure-test test -c container-structure.yaml -i foobar:latest

However, commandTests do not appear to work when there is a non-shell entrypoint (in my case httpd).
The entrypoint does not get overridden like it should:

$ cat container-structure.yaml
schemaVersion: "2.0.0"
commandTests:
  - name:  "Test"
    command: "true"
    exitCode: 0
    setup: [["/bin/sh", "-c"]]

$ container-structure-test test -c container-structure.yaml -i foobar:latest
