Thanks for using kwok!

We need to study why kind use podman returns an empty ip address,
The temporary solution is to change the server ip in the kubeconfig to 0.0.0.0 for normal use.

This pr needs to wait for the image-load function of kind to be incorporated.
kubernetes-sigs/kind#3109

Does this PR introduce a user-facing change?

NONE

Hi @helen-frank. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
