Member cluster is not ready without patch in Ubuntu #1484

Closed luolanzone closed 1 year ago

luolanzone commented 2 years ago

What happened:

I was following the quickstart in Readme file to set up kubefed, then I tried the last step kubectl -n federate-me describe federatedconfigmap my-cm to check the status, it shows CheckClusters. the kind cluster which is joined by default is not ready. Only after I tried to do the patch which is provided in fix-joined-kind-clusters.sh, it can be ready.

What you expected to happen: The cluster should be ready by default without patch according to the Readme, but now it requires patch, maybe need to update doc and fix-joined-kind-clusters.sh to do the patch in linux as well.

How to reproduce it (as minimally and precisely as possible):

Follow the steps in Readme.

Anything else we need to know?:

Environment:

OS: Linux 4.15.0-162-generic #170-Ubuntu SMP Mon Oct 18 11:38:05 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Kind: v0.11.1 go1.16.4 linux/amd64

same behavior using kubefed master commit a402d2e2750dcc3c094a29a79d8bff53b28fe15d with kind cluster image version from scripts/create-clusters.sh kindest/node:v1.21.1@sha256:69860bda5563ac81e3c0057d654b5253219618a22ec3a346306239bba8cfa1a6 under ubuntu 22.04

At the end of make deploy.kind:

I0720 15:00:44.911115  274012 join.go:934] Created secret in host cluster named: kind-kind-67dmq

But the cluster is not ready:
