use below command to switch into prod context. If you want to operate in the production namespace. You can now view the contexts and alternate against the two new request contexts depending on which namespace you wish to work against. Like virtual machines, virtual clusters partition a single physical. They have their own control plane and schedule all workloads into a single namespace of the host cluster. Compared to fully separate 'real' clusters, virtual clusters reuse worker nodes and networking of the host cluster. By default, the above commands adds two contexts that are saved into file. Virtual clusters are fully working Kubernetes clusters that run on top of other Kubernetes clusters. You can alternate against depending on what namespace you wish to work against. The above commands will create two new contexts.

This section sets our default cluster, namespace and user that kubectl will use with its commands.Ĭretae New Context: kubectl config set-context dev -namespace=development -cluster=lithe-cocoa-92103_kubernetes -user=lithe-cocoa-92103_kubernetes How to create a Kubernetes cluster locally and deploy simple front-end apps that communicate with Kubernetes. In the above command output you can see contexts section. This file also stores authentication information such as username/passwords, certificates or tokens. you can find this same info in $HOME/.kube/KUBECONFIG OR $HOME/.kube/config file. It will give you current context configuration. View Context Configuration master $ kubectl config view It will display the current context which you are using.
