Sharing my HA homelab with Nomad and Consul

Hi all,

since I could not find any good examples on the internet how to set up a HA cluster with Nomad and Consul, I would like to share my current setup. Maybe someone can benefit from it.

Hightlights are:

  • Full high-availability with 3 nodes, any one node can go down with the cluster healing itself
  • Ingress management with keepalived and Consul Connect ingress gateway, plus UDP ingress management with NGINX
  • Observation of nearly everything, including traffic between services and a lot of other metrics
  • Online backups of the databases via Nomad Actions
  • Distribution of the worker jobs across all compute nodes for Immich

The setup is split into three repositories

Comments are totally welcome! There are still some rough edges, but I’m quite happy with the setup right now.

I’m in the process of building my homelab up as well.

If you have any questions, feel free to ask here or via DM.

I’m planning on doing a detailed writeup, and it would help if I know where people are struggling.
