Without kubectl, how do you display list of names of available Kubernetes contexts that you can use from the machine?

Experience Level: Junior
Tags: Kubernetes

Answer

Use the following command:

cat ~/.kube/config|yq eval -o json|jq ".contexts[].name"

How does it work?

  • The configuration data is stored the file ~/.kube/config
  • cat command displays the conent of the file
  • yq command converts the output from yaml to JSON format
  • jq command will iterate over all child elements of element (array) contexts, name property of each child element is displayed.
