Kubectl is used to deploy different objects supported in a Kubernetes cluster. If you want kubectl to use a specific namespace and save it for all subsequent kubectl commands in that context: $ kubectl config set-context -current -namespace= Creating Objects If you want to embed client certificate data in the “cluster-admin” entry, syntax changes to: $ kubectl config set-credentials cluster-admin -client-certificate=~/.kube/admin.crt -embed-certs=true

Or, as another example, to set basic auth for, say “cluster-admin” entry, you can specify username and password as: $ kubectl config set-credentials cluster-admin -username= -password= To authorize a new user to be added in kubeconf: $ kubectl config set-credentials NAME įor example, to set only the “client-key” field on the “cluster-admin” without touching other values, we can use: $ kubectl config set-credentials cluster-admin -client-key=~/.kube/admin.key We can change the context in use by using: $ kubectl config use-context To get current context for kubectl: $ kubectl config current-context To list all available contexts: $ kubectl config get-contexts To view kubectl current configuration, use: $ kubectl config view It can be done with kubectl command itself. The general syntax for kubectl usage is: $ kubectl Set Context and Configurationīefore using kubectl commands on a Kubernetes cluster, we have to set the configuration and context first.
