Hosting Lemmy in Azure—best approach (self.selfhosted)

submitted 1 year ago by r0bbbo to c/[email protected]

Hi—I have some free Azure credits and would like to use them to host a personal Lemmy instance. I know Lemmy is containerised, but is there a preferred choice for hosting in Azure—AKS, Azure Container Apps, Container Instances? Also, any guidance on appropriate PostgreSQL configuration—I know there are some options around that.

Also, can anyone point me at what resource utilisation will look like for a Lemmy instance—I imagine disk space is more of a concern that compute usage.

Thanks for the great reply—I'll take a look at your deployment script to see if that fits my needs. I only plan to use the instance for me and a handful of friends. Like you say, data retention is probably my biggest concern so I'll look at the most sensible way to budget for that in Azure. Are there any numbers available from the major Lemmy instances? Consideration for retention policies seem like a bit of an oversight—I might do some reading to see what the plan is here.

I'm not sure if the other instances have published their numbers, I can only see what my Docker volumes look like.

But if it helps you plan, you should know that federation only involves new data. When you set up a new instance, and federate with/subscribe to a community, it will only fetch an initial 20 posts (if that). From that point forward, you will receive a copy of all posts/comments posted to that community, but you will not have anything from before you federated. So you don't have to worry about mirroring the entirety of a community's history - I'd probably be out of disk space 3 times over if that were the case.

There are ways for users to retrieve "old" posts, but it's done on an individual basis, not in bulk.
