Of the many useful things I could do with my spare time instead I’m setting up a Lemmy instance because why not. The scope of this is definitely greater than any self-hosting I’ve ever attempted, so please feel free to tell me just how much trouble I’m in. I’m just giving the broad strokes to see if I’ve made any crucial errors (other than deciding to do this at all).
And if this is a completely wrong place for a post like this or I’m missing data I’m supposed to include I apologize, I probably need a sanity check, in more ways than one.
First limitation, I’ll be hosting it on an existing Linux Mint box acting as a file share mostly and occasional gaming PC/movie streaming box. Its hardware is overkill for this, I do not anticipate issues when it is in use. It receives regular updates and weekly reboots, instance will be set to automatically restart. NVMe with loads of space for local storage, RAID SSDs for data offload/backup.
Second limitation, I hate Cloudfare and Oracle. I do not want to use either of them.
Third limitation, money. Cheaper is better. I have a URL picked out and a registrar which will give me the cheapest long term option, in case I actually keep this thing going.
Last limitation, I’m already in over my head so I’ll be relying on a lot of googling and probably some chat bots to figure things out as I go through the actual deployment process. What could go wrong?
So, Lemmy hosted on Linux Mint box using Docker containers. ISP is a good one for this I’m told, no CGNAT, largely stable public IP but I’ll have a script running in case it does change. Confirmed ports 80/443 are open. Using Caddy for the HTTPS. Closed registration to start, if by some miracle I make it to actually wanting to allow additional users it will not be fully open, and I’ll use Brevo for the email SMTP. Security wise I know I’m making it harder for myself by exposing my IP, I’m going to have UFW running and Crowdsec to help keep incoming bad traffic out.
Down the line I’ll get Lemmy updates, backups, retention rules in place/automated, and make decisions on federation, etc. Thoughts?
Just in general or because you’re setting up a Lemmy instance?
Well in general I know I’m an idiot, so for the moment I’ll just stick with Lemmy instance feedback cause that’s at least easier for me to address without expensive therapy.
allow additional users it will not be fully open
Just for trusted friends or randos? If randos, have you ever been a mod? Never set up a Lemmy instance, but I have been a mod of quite a few Reddit subs. It’s a headache I will never engage in again.
Update with a link to your instance when you’ve done it so we can show some love and support
Yes you are mad, I know as I did that over 3 years ago. Went from at home => a cheep VPS => paid for Oracle VPS.
If you go down the lemmy route (vs piefed) then I would deply with Lemmy-Easy-Deploy by @ubergeek77. this makes setting Caddy and mail simple
Good to know, I’ll take a look at those. Thanks!
Yes, you are, but aren’t we all?
I did a very similar setup very recently. Its not bad. I did try piefed first as some people suggested, but had some issues and it felt like it just wasn’t ready yet. I switched to self hosting lemmy and really like it. I also went with Brevo for email (I started with sendgrid, would not recommend).
Main difference for me is I am using cloudflare (they are my registrar and they allow me to deal with the CGNAT at no extra cost which you don’t have to deal with not to mention a pretty solid WAF for free tier). You may want to implement a WAF of some kind to keep the federation in check. I federate both lemmy and a matrix home server and it doesn’t eat up too much bandwidth.
I also like saving money, so a VPS is something I was trying to avoid. Personally, I don’t think the VPS does a much for securing your home network as people are trying to say here. It is another layer of security, but it’s not a panacea. Not saying I’ll never try it though.
I actually started on a VPS… I moved off because I was pegging the RAM and adding more to my plan was quite expensive. Performance is MUCH better on my home server with plenty of RAM.
Lemmy eventually plans on having an invite system, you could maybe use that when it comes out

(You can also do this manually with the application questionnaire field and a spreadsheet)
Probably, yes, but I still love you
You sound like my wife.
Plot twist. You are not married…
Sure I am, but depending on how much of my free time goes into this we’ll see if it stays that way…
I would not do that without first looking into applicable laws regarding legal liability for content and requirements to remove things. Depending on where in the world you are, this can be a minefield.
Yeah that’s a future line item if I make it far enough, heh. It’s under the “who to federate with” bullet point.

Best of luck on your new hobby!
I didn’t see anything in your post that set off alarm bells
If you’re looking to save some cash and your ISP gives you a stable public address you could utilize a Dynamic DNS provider (ala duckdns) instead of registering a domain
Good point, that was purely a vanity issue: I have a specific name I want for my instance, and I wanted it to be as short a URL as possible so I was willing to spring for the domain. I’m not saying I’m doing all this just for the pun I have in mind, but I did spend far too long on that step of my deployment plan.
Not lemmy, but piefed. The easy way, try yunohost.
Cool man… I did the same last year, best decision ever.
Pretty easy too
Not necessarily, but why choose a project that needs interfacing with an existing ecosystem where it can mostly only be noise?
If you want to deal with a complicated mess of a system as a project, you could always grab Arch
Thought about doing something very similar, I’ll be curious to hear the feedback and your experience
If at some point in the near future you step outside and hear a weird screaming sound echoing around the globe, that’s me.
Best of luck to you!!! I just went through this last week and wow it was a challenge. I went the docker route not using ansible…and yah by far the worst install I ever went through of all the self-hosting projects I have setup…but my setup was largely complicated by the fact I had an Apache reverse proxy setup in front of the nginx proxy that has an example config provided…finally figured it all out, but yah fun times 😂 happy to help if you get stuck.
Not sure what your solution was, but I eliminated the reverse proxy from the official compose stack and configured my existing reverse proxy to point directly at the lemmy containers. It works well for me.
Thanks. Yah that was what I tried to accomplish using Apache but couldn’t get the correct proxypass statements in Apache that would do the correct passing depending on the header received. Tried asking an LLM for help but never got it to work, so ended up doing a basic/straight pass through apache to a local VM running nginx as an outer proxy which proxy’s to the nginx internal proxy…its messy as all hell but it works 🤷
I don’t know enough about Apache to say one way or the other, but based on what you described, you SHOULD be able to get rid of the internal proxy. Since both the inner and outer are both NGINX, getting the settings right shouldn’t be a problem.
But, on the other hand, if it works it works!
Good call. Perhaps on a rainy day I’ll take another crack at it…but yah the ports are exposed through docker so yah, makes sense. Thanks and have a great day!
One of my earlier deployment plans had me using Ansible, then a bot aided revision had me remove it since I’m doing a single machine install and a fairly straightforward process. From my understanding I’ll get a better learning experience not using it so I figured that was better.
Yah i had never used it either, alot of the tutorials I found suggested it, and what threw me for a loop and was the ultimate Aha! moment for me was there is an ansible version and a non ansible version for the docker configs with different options in each, and the ultimate key thing I overlooked is on github, I kept using the “main” development branch which had changes that didn’t work with the stable .19 version. Switching to the .19 branch on GitHub and referencing those configs made it all click
