Using with Podman about dockernel HOT 3 OPEN

Hi @marcelned. Dockernel uses Docker API (the Python library), not Docker CLI, and so substituting docker command with podman will have no effect.

It might be that I'm completely misunderstanding the issue, but I'm going on a vacation shortly, so I'm unable to analyze this deeper.

I haven't used podman, but if you'd like dockernel to support it - I'll consider looking into it. That will have to wait until I can shift my focus back onto dockernel, as currently I'm a bit busy with other projects.

I got it working manually by adapting from this answer

kernel.json:

{
 "argv": [
  "/usr/bin/podman",
  "run",
  "--rm",
  "--network=host",
  "-v",
  "{connection_file}:/connection-spec:z",
  "-v",
  ".:/work:z",
  "localhost/pyspark:3.2",
  "python",
  "-m",
  "ipykernel_launcher",
  "-f",
  "/connection-spec"
 ],
 "display_name": "spark-env",
 "language": "python"
}

Adding the current work directory to bind as volume, with /work set as WORKDIR in dockerfile, works like a charm.

Looks like Podman actually comes with a REST API. The claim is that it is similar to that of Docker, so it should be possible to marry Dockernel with it.

I'll make sure to steer the source code towards enabling backend plularity, but I conside the implementation of Podman as a backend a low priority for now.
