Unknown certs by ryannix123

Just FYI, if you receive this error when installing something such as a service catalog, here is the fix.

Issue

Unable to see the projects, nodes, services when using oc command. Getting same error in oc adm diagnostics.

`ERROR: [CED1008 from controller openshift/origin/pkg/oc/admin/diagnostics/cluster.go]
       Unknown error testing cluster-admin access for context 'default/mycluster.com:8443/sadmin':
       Post https://mycluster.com:8443/apis/authorization.k8s.io/v1/selfsubjectaccessreviews: x509: certificate signed by unknown authority
       
ERROR: [CED1008 from controller openshift/origin/pkg/oc/admin/diagnostics/cluster.go]
       Unknown error testing cluster-admin access for context 'default/mycluster.com:8443/system:admin':

Resolution

Backup ~/.kube/config file on master.

$ mv ~/.kube/config /tmp/kube_config_backup

Copy config from /etc/origin/master/admin.kubeconfig and then retry oc command.

$ cp /etc/origin/master/admin.kubeconfig ~/.kube/config

Diagnostic Steps

Verify that cluster is up and running and working as expected.

$ oc status --config=/etc/origin/master/admin.kubeconfig
$ oc get nodes --config=/etc/origin/master/admin.kubeconfig
