getpod

Access pods quickly without using the clipboard or listing all pods first. Here's a typical use case:

$ kubectl logs `getpod kube-proxy` -f

What have we gained? This line replaces two common approaches. In many cases we would use the clipboard or type in the hash component of the name:

$ kubectl get po | grep kube-proxy
kube-proxy-cf2df                            1/1     Running   0          5h
kube-proxy-8dj6v                            1/1     Running   0          5h
kube-proxy-s6wvq                            1/1     Running   0          5h
$ kubectl logs kube-proxy-cf2df -f

What about a one-liner? It's straightforward but hardly concise:

$ kubectl logs `kubectl get po --no-headers | grep kube-proxy | cut -d' ' -f1 | head -n1` -f

Why not just a shell script? Mainly because it probably will not work as intended on Windows. It is hard to overestimate the number of Kubernetes users using kubectl via Git Bash or PowerShell.

Usage

$ getpod -h
Usage: getpod [-kubeconfig=PATH] [-a] [-n NAMESPACE] REGEX
  -a	return all matching pods
  -kubeconfig string
    	(optional) absolute path to the kubeconfig file
  -n string
    	namespace

The search expression is interpreted by the Golang regexp package (sadly not PCRE).
