[POC] odo without kubernetes cluster / odo on podman

[kadel]

/kind user-story

User Story

As an odo user, I want to be able to run my development environment locally without requiring kubernetes/openshift cluster
So that

• I don't need to run the cluster locally and save resources
• I get a quick response (quicker than when using cluster)

Acceptance Criteria

• It should be possible to run odo dev on a simple devfile that doesn't use kubernetes components

more info

It should be possible to leverage podman for local development.
Podman already understands some of the kubernetes resources https://docs.podman.io/en/latest/markdown/podman-play-kube.1.html

The idea is that odo will try to use existing k8s resources that it generates and just pass it down to the podman play kube command.

• deployments generated by odo can be almost used as it is with two exceptions

  • hostPort needs to be added to tell podman to expose port
  • emptyDir is not supported by podman and needs to be replaced with PVC

• Service is not supported by podman play kube. But it is not necessary required to make everything work.

• The most work will be to re-write file syncing logic to work with podman container instead of the container running on the cluster.

• podman cp command can be used for transferring files between local filesystem and container
