Testpod

Util to run a Pod for testing in your currently selected Kubernetes namespace via kubectl and enter a shell in it.

Installation

go install github.com/sbreitf1/testpod@latest

Usage

First run will create a default configuration in ~/.config/testpod (XDG compatible). Execute testpod --dry-run to only create a default configuration file without applying it to Kubernetes.

Edit the configuration file to set default image and shell to execute, as well as additional labels to apply to your Pod and configure a NetworkPolicy.
