Re: [onap-discuss] K8s in ONAP - DDF follow up

Tue, 23 Jul 2019 03:20:38 -0700

Hi again,

I've managed to launch some more basic tests today and it looks like my change doesn't fix this issue completely. It fixes creating network resources and they are created correctly (please see log below), however pods are having issues with creating sandbox due to multus issues. Nevertheless I think that pod sandbox issue may have root cause anchored somewhere else, so probably additional fix may be needed.

Hi Łukasz, All

I came across the same issue as you today. I think I've located culprit of this error and I've addressed it in review https://gerrit.onap.org/r/c/multicloud/k8s/+/91812.
Please note it's work in progress as I didn't manage today to thoroughly test it, but I expect to do it tomorrow morning.

With Regards,
Konrad Bańka
