Server Configuration

At the time of writing, I have a single 6 core VDS from NetCup that I use to host my personal projects. Initially, I started out with docker and having folders of compose files. I quickly ran into issues re-deploying multiple services at once, shoehorning traefik configuration into docker and various other tidbits here and there.

So I decided to bite the bullet and dive into the fabled/dreaded Kubernetes.

It's important to note that this is mostly for learning, a single node cluster isn't very effective and honestly makes things a lot harder in a lot of places compared to docker config. However, I'm fascinated at the fact that you can interact with a single node cluster the same way you'd do with hundreds of clusters, it's a pretty powerful abstraction!

Also, technically I'm using k3s for this single node cluster.

Useful Commands

Get the Bearer Token

kubectl -n <namespace> create token <user>

Load in Environment Variables via .env (Although, based on this stackoverflow post, there is some odd behaviour with the command)
```
kubectl create secret generic <secret-name> --from-env-file=.env
```

Perform PVC Storage Expansion

kubectl patch pvc <name> -p '{"spec":{"resources":{"requests":{"storage":"<amount>"}}}}'

Acknowledgement

Sincere thanks to one of my best friends winston for helping me set up the cluster, troubleshoot configurations and taking the time to walk me through concepts. I really couldn't have done it this fast without him!
