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.

That's a nice suggestion. I guess I can make the CI build a Docker image containing my website's files and then have a plugin for it to restart the pod that serves the website so it fetches the latest image.

K8s is that “restart” mechanism.

Docker images are just the thing that it restarts.

Docker itself or “docker compose” can restart images and do everything you need, but if you want to go the full k8s it’s complicated but great learning

One simple way to pull the new image into your cluster is to overwrite the latest tag, specify imagePullPolicy: Always in your deployment and then use kubectl rollout restart deployment my-static-site from within your pipeline. Kubernetes will then terminate all pods and replace them with new ones that pull the latest image.

You can also work with versioned tags and kubectl set image deployment/my-static-site site=my/image:version. This might be a bit nicer and allows imagePullPolicy: IfNotPresent, but you have to pass your version number into your pipeline somehow, e.g. with git tags.
