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.
