My 2023 Homelab Setup

mudkip.me My 2023 Homelab Setup

Homelab is a place where you can store all your family’s data, self-host applications and services, locally stream media, and experiment with various technologies. A Homelab can start with low-power

I wrote a blog post detailing my homelab setup throughout 2023. It includes the hardware I use, as well as the applications I selfhosted. I also detailed how I automate my home Kubernetes cluster and how I back up my data.

makes me wander, what ai/prompt did you use to generate the pic. Looks neat!

- Looks like you wandered into autocorrect changing the word "wonder" on you

- I use DALL·E via ChatGPT Plus. The prompt is the first two paragraph in this post plus "Draw a picture for this article titled My 2023 Homelab Setup".
  
  I retried several times and picked my favorite one :)

I really like self hosting too but Kubernetes is overkill in complexity. I use nomad. :)

- In a cluster? I'm actually thinking about using Nomad between my three sff pc that I use as servers, but I have no clue as to how to sync storage between them (container side I mean, with nextcloud data for example)?

  Storage is hard to do right :(
  
  If you can get away with it, use a separate NAS that exposes NFS to your other machines. Iscsi with a csi might be an option too.
  
  For databases, it's usually better to not put their data on shared storage and instead use the databases built in replication (and take backups!).
  
  But if you want to go down the rabbit hole, check out ceph, glusterfs, moosefs, seaweedfs, juicefs, and garagehq.
  
  Most shared file systems aren't fully posix compliant so things like file locking may not work. This affects databases and sqlite a lot. Glusterfs and moosefs seen to behave the best imo with sqlite db files. Seaweedfs should as well, but I'm still working on testing it.

  Yeah in a cluster with consul. Consul gives automatic service discovery and works with traefik so I don't even have to care which node my service is running on since traefik knows how to find it using consul.
  
  For the storage I went with a simple solution. I installed nfs on a machine running in nomad, and then configured the nomad clients to mount that disk. All of this with ansible so I don't have to do it more than once.

Nice, gave me a couple of ideas about some other software I might be interested in hosting for myself.

I couldn't get the top-level navigation shortcuts to work in your blog, just FYI.

- Thanks for pointing out! It should be fixed now 😄

Nice setup. Going to steal some ideas for my own setup!

The manifest of my Kubernetes cluster is managed in a Git repository and is automatically deployed via a GitOps tool named Flux CD. When I push changes to the repository, such as adding a new application or upgrading Docker images, the deployment occurs within a few minutes.

This is the way.

Although I use Flux ImageUpdateAutomation instead of Renovate Bot. Did you consider using Flux to do auto updates? Are there any downsides that made you choose Renovate Bot instead?

- Thanks! I looked at the documentation of Flux image update automation first but I didn't figured out how to handle Helm chart versions, and it seems it requires manual "marker" to handle image tags in Helm values (which Renovate can manage automatically), so it looks like Renovate fits my needs more.

Upvoted for the pic. Did you draw that? Looks cool :)

Is that really the chair you're going for?

not sure that's legal to use pleX in 2024, and 90% of that is never used
