v0.4.0 causes core dump in kind cluster pods #31

Closed Cerebus closed 1 year ago

Cerebus commented 2 years ago

30 resolves the deploy issue, but this started happening on kind:

ifconfig executes properly and this doesn't seem to affect functionality (though I haven't tested w/ my tc sidecar yet).

Hi @Cerebus , I didn't fully understand what's the issue. Is the issue with ip addr command? Do you have steps to reproduce this?

Closing as OBE since I'm not using kind any more.
