Formatting Output with kubectl

To format the output of kubectl commands, you can use the -o or --output flag followed by the desired output format. Common output formats include:

  • json: Outputs the resource in JSON format.
  • yaml: Outputs the resource in YAML format.
  • wide: Outputs additional information in a table format.

Example: Get Pods in YAML Format

kubectl get pods -o yaml

Example: Get Services in JSON Format

kubectl get services -o json

Example: Get Nodes in Wide Format

kubectl get nodes -o wide

watch

To continuously watch for changes in resources, you can use the --watch or -w flag. This will keep the command running and update the output as changes occur.

kubectl get pods --watch
