# browse samples by interactively selecting resource type first
kubectl examples

# interactively select from filtered resource type
kubectl examples Pod

See full usage in readme section: https://github.com/lalyos/kubernetes-examples#usage

Todo

[ ] Once its been merged, the urls can be fixed to point to the original git repo instead of the fork.
[ ] Could be submitted as an official krew plugin: https://krew.sigs.k8s.io/docs/developer-guide/release/new-plugin/

This is great!

Have raised: #10 for submission as a krew plugin

A couple of things before merging:

• the yamllint fails - have a look at: https://github.com/ContainerSolutions/kubernetes-examples/pull/9/checks?check_run_id=1095366514
• add a comment to the README under 'Sections' for the 'plugins' folder
• we can change the url to the 'right' one before merging
