Finally, I’ve had enough and decided to get rid of Git, GitHub, and continuous integration to manually upload this site, generating the build from my local machines. When you learn to use Hugo, everywhere you look, you’re shown how to do a deployment with GitHub, but I think all of that is too much for the needs of most people and ends up increasing the technical debt that you constantly have to carry when maintaining the site.
Furthermore, I don’t think it’s environmentally sustainable to have to deploy a container or VPS every time you have to do a build when those tools are already installed on my machines. We’ll see how long I last with this setup, but for now, something simpler seems appropriate.
