Kubectl Grep
Filter Kubernetes resources by matching their names
Compatibility
please refer to Kubernetes version policy and CHANGELOG for supported version matrix.
Why we need it?
playing with Kubernetes is my daily job, and I normally search pods by pipe,
grep, --label, --field-selector, etc. while hunting abnormal pods, but
typing such long commands is quite annoying.
Before change, we usually filter pods by the following commands,
$ kubectl get pods -n star-lab | grep "flash"
With this plugin installed, you can filter pod with kubectl grep easily
$ kubectl grep pods -n star-lab flash
