What's the best approach to deploy a static website to K8s cluster from a CI pipeline? (infosec.pub)

I have a small VPS that hosts some services I use daily and I'd like to migrate that to a K8s cluster. One of the services being hosted is my personal website, built with Hugo and served by Caddy.

Right now, I have the code for my website on Codeberg and I have a CI pipeline that builds the website and uploads it to my VPS via rsync.

I want to move the website to the k8s cluster, but I have no idea how to do it "securely". What I have right now is a separate user on my VPS called deploy and it rsyncs the files to the data directory Caddy is using to serve my files.

I thought I could do the same on the k8s cluster server, but it's usually not a good idea to mount host paths with k8s unless absolutely necessary, because container escaping is an actual problem.

So far the only alternative I could think of is to change the CI pipeline to publish my website on another branch and signal it to my K8s cluster so the files should be updated, but I'd like to know what better options exist and how easy they are to setup.

Thanks for the suggestions!

I ended up configuring my CI pipeline to build a Caddy docker image that ships with my website files. The pipeline is also publishing the container image to the Codeberg registry and I apply the new image repo and tag to the Caddy Helm chart I found on ArtifactHub.

The only thing that's left is to setup the CI to automatically restart the pod when a new image is pushed, so it will always have the latest version.

It was easier than expected and I had a few issues like my stylesheets not being applied and image files not rendering, but it was solved by changing the pathType field on the ingress configuration to Prefix.
