Reuse minikube podman

[JMesens]

In my setup I have no local docker daemon and a minikube running in virtualbox on mac. On the minikube podman is working fine. (minikube ssh) Now I was trying to use podman's PODMAN_VARLINK_BRIDGE to connect to the minikube podman.

This would be nice that I could do podman build and the actual build would be done in virtualbox so that the image is also available for minikube to use.

I made the decision to not bother with varlink for the minikube image, but I suppose that could be revisited. Originally I was a bit concerned about the root requirement for ssh, but now works with sudo.

If I remember correctly, what needs to be done is to install the varlink binary (for the bridge), and to install the socket-activation for systemd. Optionally deploy a resolver,* but everyone ignores that...

• /etc/systemd/system/io.podman.socket

• /etc/systemd/system/io.podman.service

Could you open an issue over at minikube, instead ?

I don't think that this will require any changes to libmachine.

(*) The resolver allows you to say io.podman, instead of hardcoding the socket path.

$ sudo varlink resolve io.podman
unix:/run/podman/io.podman;mode=0600

The downside is of course that you have to hardcode /run/org.varlink.resolver instead...

So - as long as podman is the only thing in the world that uses varlink, it's not really a win.

Packaged varlink for minikube at https://github.com/kubernetes/minikube/compare/master...afbjorklund:varlink

I think the systemd socket/service are available from podman's make install.systemd

The varlink support is being removed upstream, so I think that I will continue with using ssh.

Using the systemd units requires ssh as root, so better to use the varlink bridge after all...

The command to run is: sudo varlink -A \'podman varlink \$VARLINK_ADDRESS\' bridge
