A Nomad job example setup for Lemmy (github.com)

I am selfhosting Lemmy on a home Nomad cluster - I wrote the job files from scratch because I did not find anybody else who attempted the same.

I thought I'd share them and maybe they will serve as a starting point for someone using a similar selfhosted infra!

Nomad brings a few benefits from Lemmy specifically over Ansible/Docker, most notably some horizontal scaling across more than one machine.

Feedback welcome!

Yes! Another Nomad fan! I was working on something for this too! Couple things:

  • run nomad fmt to make it a little easier to read and line things up better
  • Nomad 1.6 beta is out and with it comes Pack 0.1 GA and fixes the dependency gaps for Packs. Would be super useful to have this written in pack :)
  • with 1.6 will also have the registry hosted on the nomad site so it’ll get a lot more visibility.

There are dozens of us!

  • nomad fmt was applied already - granted it is not a small easy to read job file, it might be easier to split it up into separate jobs
  • I will look into making this into a Pack - I have never built one because I have never shared my config like this before. I don't know how popular they are among selfhosters either!

I think an easy first step would be to contribute a sample job file like this into the Lemmy docs website. Then people can adapt to their setups. I find there is a lot more to configure in Nomad than in Docker compose for example because you stop assuming everything will be in a single box, which changes networking considerably. There is also whether to use Consul, Vault etc.

Agreed as a first step. Pack is relatively new and not popular currently because there isn’t a great “marketed” repo so to speak. Hopefully that’ll change with it being on the nomad website.

Personally I think lemmy instance admins could benefit a lot with the scaling capabilities of Nomad. Hopefully is keeps growing in popularity.
