來把預設需多次加、解密封包的flannel，更換一下成host-gw
因為我的環境剛好就有WG，所以就沒有使用內建的host-gw, 不然就更加快速和方便

不過最好是開始安怖建環境就先規劃好，而不是像我中途更換，因為會中斷業務

這個是非常方便可以HPA自動橫向縮、放的功能

完成圖

今天來記錄地端 Gitea, 目的：不倚賴雲端，有更好安全性。寫得差的程式比較不會被發現…

root@chunk03:~# mkdir -p /var/lib/gitea

root@chunk03:~# mkdir -p /var/lib/local-registry

root@chunk03:~# mkdir -p /var/lib/gitea-runner

root@chunk03:~# chown -R 1000:1000 /var/lib/gitea /var/lib/gitea-runner

因為我這台有K3s master, 純管沒做事，負載很低，所以直接拿來用(正常最好分開
