Podman driver doesn't remove volume or network on delete

[afbjorklund]

This makes the next create attempt fail:

🤦  StartHost failed, but will try again: creating host: create: creating: setting up container node: creating volume for minikube container: sudo -n podman volume create minikube --label name.minikube.sigs.k8s.io=minikube --label created_by.minikube.sigs.k8s.io=true: exit status 125
stdout:

stderr:
Error: volume with name minikube already exists: volume already exists

🔄  Restarting existing podman container for "minikube" ...
😿  Failed to start podman container. Running "minikube delete" may fix it: podman inspect ip minikube: sudo -n podman container inspect -f {{.NetworkSettings.IPAddress}} minikube: exit status 125

stderr:
Error: error inspecting object: no such container minikube

The filter option is failing, for some reason:

$ sudo -n podman volume ls --filter label=name.minikube.sigs.k8s.io=minikube
$ sudo -n podman volume ls 
DRIVER      VOLUME NAME
local       minikube
$ sudo -n podman volume inspect minikube

It works OK in the docker driver:

$ docker volume ls --filter label=name.minikube.sigs.k8s.io=minikube
DRIVER              VOLUME NAME
local               minikube
$ docker volume inspect minikube
[
    {
        "CreatedAt": "2020-11-14T15:22:40+01:00",
        "Driver": "local",
        "Labels": {
            "created_by.minikube.sigs.k8s.io": "true",
            "name.minikube.sigs.k8s.io": "minikube"
        },
        "Mountpoint": "/var/lib/docker/volumes/minikube/_data",
        "Name": "minikube",
        "Options": {},
        "Scope": "local"
    }
]

So it looks like a bug in podman.

[afbjorklund]

Reported upstream as containers/podman#8341

The workaround is to remove the volume explicitly, after doing minikube delete

sudo podman volume rm minikube

Maybe minikube should remove the volumes explicitly too, like it creates them ?

[afbjorklund]

As mentioned in #9714, this cleanup now also applies to the created network.

sudo podman network rm minikube
