Description of problem: kubefed2 should set registry-namespace = federation-namespace as federation controller-manager when limited-scope=true Version-Release number of selected component (if applicable): $ oc get clusterversion NAME VERSION AVAILABLE PROGRESSING SINCE STATUS version 4.0.0-0.nightly-2019-03-25-180911 True False 57m Cluster version is 4.0.0-0.nightly-2019-03-25-180911 kubefed2 version: version.Info{Version:"0.0.6", GitCommit:"de6a0a909418f5ddf2d04d232b0ca55aa9cffb49", GitTreeState:"clean", BuildDate:"2019-03-14T00:43:37Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"linux/amd64"} Federation v2 controller-manager version: version.Info{Version:"0.0.6", GitCommit:"de6a0a909418f5ddf2d04d232b0ca55aa9cffb49", GitTreeState:"clean", BuildDate:"2019-03-14T00:43:37Z", GoVersion:"go1.11.5", Compiler:"gc", Platform:"linux/amd64"} How reproducible: Always Steps to Reproduce: 1. Install a namespace scoped federation controller manager in the default federation namespace: federation-system $ oc exec federation-controller-manager-7b4bfd556-588t2 -- ps -ef|grep controll 1000480+ 1 0 0 06:28 ? 00:00:01 /root/controller-manager --federation-namespace=federation-system --install-crds=false --limited-scope=true --registry-namespace=federation-system -v=5 --logtostderr 2. Join a cluster to a federation with limited-scope=true: kubefed2 join cluster1 --add-to-registry --cluster-context=$(oc config current-context) --limited-scope=true Actual results: F0326 14:39:45.478012 6362 join.go:129] error: namespaces "kube-multicluster-public" not found Expected results: Cluster join to a federation successfully. Additional info:
I definitely think that some improvements are needed in the area of CLI experience, but we do not have an easy way to implement this currently. It's likely that coming component configuration work will help make this possible in the future.
I've filed an upstream issue to track updating kubefed2 to use FederationConfig instead of requiring --registry-namespace or --limited-scope: https://github.com/kubernetes-sigs/federation-v2/issues/748
In 0.0.10 kubefedctl has been updated to discovery the scope and registry namespace so the options are no longer required have have been removed. Bumping to 4.1.
