KubeConfig

• Take me to Video Tutorial

In this section, we will take a look at kubeconfig in kubernetes

Client uses the certificate file and key to query the kubernetes Rest API for a list of pods using curl.

• You can specify the same using kubectl

  

• We can move these information to a configuration file called kubeconfig. And the specify this file as the kubeconfig option in the command.

  $ kubectl get pods --kubeconfig config
  

Kubeconfig File

• The kubeconfig file has 3 sections
  • Clusters
  • Contexts
  • USers

  

  

• To view the current file being used

  $ kubectl config view
  

• You can specify the kubeconfig file with kubectl config view with “–kubeconfig” flag

  $ kubectl config veiw --kubeconfig=my-custom-config
  

  

• How do you update your current context? Or change the current context

  $ kubectl config use-context <context-name>
  ex: 
  $ kubectl config use-context prod-user@production
  

  

• kubectl config help

  $ kubectl config -h
  

  

What about namespaces?
