I tried to use the Kubernetes Continuous Deploy Plugin but its seem it ran on the slave and deploy the app, but I want to deploy K8 Apps in K8 cluster not in jenkins slave.
As it described at wiki-pages you need configure access to your kubernetes cluster.
From documentation:
In the "Kubeconfig" dropdown, select the > kubeconfig stored in Jenkins.
in kubeconfig you store the access to your cluster, without this it would not work.
