I could not find any documentation on how to connect docker pipeline to connect to the kubernetes cluster What do i add to the Jenkinsfile to be able to connect?

I could not find any documentation on how to connect docker pipeline to connect to the kubernetes cluster

What do i add to the Jenkinsfile to be able to connect?

Answer

Where do you have the kubeconfig? as credentials in jenkins..i am able to use it with *kubernetesDeploy* with reference of the crdentials as kubeconfigId here is link to the plugin https://wiki.jenkins.io/display/JENKINS/Kubernetes+Continuous+Deploy+Plugin issue now is how do i reference that in docker pipeline in jenkinsfile so when i run something like helm or kubectl it is able to use that kubeconfig credential to connect to the kubernetes cluster
