kn fails when KUBECONFIG multi config files

[csantanapr]

kn doesn't support when the env variable KUBECONFIG has multiple files

As reference: https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/#append-home-kube-config-to-your-kubeconfig-environment-variable

For example in my setup I use IKS and have multiple cluster I deal with, so I load KUBECONFIG variable with multiple KUBECONFIG paths including the default one.

echo $KUBECONFIG

value:

/Users/csantanapr/.kube/config:/Users/csantanapr/.bluemix/plugins/container-service/clusters/cluster1/kube-config-wdc04-cluster1.yml:/Users/csantanapr/.bluemix/plugins/container-service/clusters/cluster2/kube-config-dal13-cluster2.yml

This allows to use things like kubetcx

$ kubectx
cluster1
cluster2
docker-desktop

The CLI kubectl works fine current context is cluster1

kubectl get ns | grep knative
knative-build        Active   98m
knative-eventing     Active   98m
knative-monitoring   Active   98m
knative-serving      Active   98m
knative-sources      Active   98m

The problem is kn doesn't work and recognize the current context from the merged files like kubectl

kn service list              
stat /Users/csantanapr/.kube/config:/Users/csantanapr/.bluemix/plugins/container-service/clusters/cluster1/kube-config-wdc04-cluster1.yml:/Users/csantanapr/.bluemix/plugins/container-service/clusters/cluster2/kube-config-dal13-cluster2.yml: no such file or directory

This should be fixed by PR #36.

But PR #36 has no activity since 3 months ago and it’s closed 🤷🏻‍♂️

@csantanapr
My bad, selected wrong PR from dropdown, this is correct one #172

Thank you 🙏🏻

Still didn't work if:

$ ./kn service list --kubeconfig=$KUBECONFIG
stat /Users/bjxzi/.kube/config:/Users/bjxzi/.bluemix/plugins/container-service/clusters/eirini/kube-config-dal10-eirini.yml:/Users/bjxzi/.bluemix/plugins/container-service/clusters/knative/kube-config-dal10-knative.yml:/Users/bjxzi/.bluemix/plugins/container-service/clusters/mycluster/kube-config-dal10-mycluster.yml:/Users/bjxzi/.bluemix/plugins/container-service/clusters/eirini-deploy/kube-config-dal10-eirini-deploy.yml:/Users/bjxzi/.bluemix/plugins/container-service/clusters/knative-deploy/kube-config-dal10-knative-deploy.yml: no such file or directory
