rubber-duck

🧐 A rubber duck in your cluster, help to debug everything

Swiss Army Knife or Doraemon Pocke**

To debug a kubernetes cluster / component(middleware) / pod(business), it not similar to debug your local machine, you need to take care of the network, permission, and so on. This project is a collection of tools for k8s debugging, And classify and organize them according to scenarios, so hope they can be used right out-of-box.

Structure

It contains tools - e.g. oauth2-proxy, nginx, httpbin, with its artifacts, source-code, dockerfile and kustomization.

They, combined with kustomize in different scenarios, can be used to debug different problems.

Features

• find a way to reduce the code of kustomization.yaml (or auto generate)
• makefile, utilize the envsubs with kustomize
  • keep it simple stupid, declaritive first
• tui engine for daily operations
  • see detials inrubber-duck-cli
• curl as sidecar (kustomize patch)
• gitclone as sidecar
  • ❗not safe
• devcontainers
• composed wiki page (patten of readme)
• prod ready: add probe, image pull policy, resource limits ...
