I am not sure either what I am trying to do is possible or correct way.
One of my colleague spinup kubernetes gce cluster (with 1 master and 4 minions.) in a project which is shared with me as owner access.
After setup he shared his ~/.kubernetes_auth keys along with .kubecfg.crt, .kubecfg.ca.crt and .kubecfg.key. I copied all of the at my home folder and setup the kubernetes workspace. I also set the project name as a default project in geconfig. and now I can connect to the master and slaves using 'gcutil ssh --zone us-central1-b kubernetes-master'
But when I try to list of existing pods using 'cluster/kubecfg.sh list pods'
I see
"F1017 21:05:31.037148 18021 kubecfg.go:422] Got request error: Get https://107.178.208.109/api/v1beta1/pods?namespace=default: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "ChangeMe")
I tried to debug from my side but failed to come any conclusion. Any sort of clue will be helpful.
I figured out a workaround: set the -insecure_skip_tls_verify option
In kubecfg.sh, change the code near the bottom to
else
auth_config=(
"-insecure_skip_tls_verify"
)

Obviously this is insecure and you are putting yourself at risk of a man in the middle attack, etc.
You can also copy the cert files off of the master again. They are located in /usr/share/nginx on the master.
It is probably due to a not implemented feature, see this issue: https://github.com/GoogleCloudPlatform/kubernetes/issues/1886
you can copy the files from /usr/share/nginx/... on the master into your home dir and try again.
