Playing Drone and Gitea on local machine with k3d(k3s)

Playing Drone and Gitea on local with k3d(k3s)

Run full ci cd solution on kubernetes in local box for fun ?

What we going to build?

• A tiny k8s cluster by k3s
• A tiny git repo system by gitea (installed by helm)
• A tiny ci cd system by drone (installed by helm)

They are all golang!

• quick start,restart,install,upgrade. all in a few seconds
• easy understand prototype CICD
• easy play k8s cluster (API compatible , not really k8, k3 instead 😊)

Understand the tweak

Before I walk through steps in INSTALL.md, let 's understand it.

• Use k3d to launch k3s , 1 server + 2 workers for example, so the whole k3s cluster running on 3 docker containers.

• Once we get k3s cluster up which takes 5,6 secs (thanks to k3d 😋) we install gitea and drone through its helm charts

• External access is through traefik ingress, here we need create kubernetes ingress for both drone and gitea,and local hosts file as local box DNS resolve

• Internal connection between drone and gitea (for oauth purpose) is through kubernetes service.

• We need to use consistent dns name for both ingress and kubernetes service , as the server name configured for gitea and drone will be mixed used by webhook,oauth and external access. I choose gitea & drone in this demo

About the charts

I use official chart for drone and k8s-land chart(3rd party) I found in github for gitea, however to get all work in k3s I have to create additional ingress as well as service to get above requirement meet.
