Overview
User may interact with OpenShift by sending REST API invocations into an OpenShift master. Project-related queries and administrative commands may be sent with oc. Special administrative commands related to core OpenShift services, may be sent with oadm
State
Both oc and oadm maintain state on the client host, under ~/<user>/.kube/<cluster-identifier> directories, and configuration in ~/<user>/.kube/config. Example:
~ovidiu/.kube/master.openshift.novaordis.io_443
Context
The context of an invocation consists in a project (namespace) name, an OpenShift cluster address, and the name of the OpenShift user. The current context is maintained in under .kube/config:
[...]
