Use both GitHub and Gitea

Even though we self-host Gitea, you may still want to use GitHub as a backup and for discovery.

Add both push URLs (replace my repositories with yours):

git remote set-url --add --push origin [email protected]:ops/homelab
git remote set-url --add --push origin [email protected]:khuedoan/homelab

Now you can just run git push like usual and it will push to both GitHub and Gitea.
