@nutomic@lemmy.ml , just for debug: I used the Dockerfile provided by ubergeek and I was not able to build up the image (with no cross compile) untill I changed ARG RUST_VERSION=1.76 into ARG RUST_VERSION=latest. This change was NOT necessary on amd64. You said your matrix user was able to run dessaline’s image flawlessly on arm64 (raspberry), but this sounds weird to me :-\

Using this image --> https://github.com/ubergeek77/lemmy-docker-multiarch

    #image: dessalines/lemmy:0.19.3
    image: ghcr.io/ubergeek77/lemmy:0.19.3  

the very same docker-compose.yml works even on rpi5 (this instance I’m writing from is the one that now works even on 0.19.3 while with dessaline’s one does not). I just changed that line: there must be something in dessaline’s way of building the image that my pi doesn’t like (if on yours it works).

i’m not using ansibile, I’md directly using docker compose… the same file on an amd64 platform works, while on rpi it fails :-\

I treid version 0.19.3 on AMD64 platform and it works out of the box. The problem is only on arm64, such as on RPI.

By the way, is it only me having this problem?

Hi mate, to be honest I tried both authenticated (on my own instance) and not auth. But what is strange is that from lemmy I can contact a mastodo user and even DM him (my other username in mastodon), but there I don’t receive anything -.-

I don’t get the question… Docker is awesome for developing, but to put things on production too. It just avoids you the hassle of configuring a virtual machine / server from scratch since you can use prebuilt minimal images of the software you need. If you get in trouble you can restore things easier than on a whole compromised system. An update consists in the vast majority of times in changing a tag inside a docker-compose.yaml file. You have resource optimisation vs virutal machines, and so on. I don’t use docker to develop at all, I use it for production. And when you don’t need the service you installed anymore, you can just delete it and the system stays clean wihtout orphan files.

@AlexPewMaster@lemmy.zip I’m in your situation. At the moment on my RPI 5 I’m hosting (via docker) the followings:

• lemmy
• mastodon
• gotosocial
• peertube
• pixelfed
• grav CMS
• matrix homeserver (synapse)
• gitea
• nextcloud And outside docker
• teleport cluster
• nginx for some reverse proxy
• minecraft java 1.20.1 server

For the sake of clarity, here is my docker ps -a | wc -l

cyberpingu@vega:~ $ docker ps -a | wc -l
36
cyberpingu@vega:~ $ 

Almost everything is behind a reverse proxy (on another machine, a rpi4 with KVM) with an argo tunnel. And again

So if the question is “Is it enough a RPI 5”? The answer is yes, it is enough (at least for moderate traffic OFC). If the question is “I have to buy hardware: is a RPI 5 the best choice?” the answer may vary depending on many things. As you’ve been told, if GPIO is not a problem, maybe a minipc is better.

@Marsupial@quokk.au that’s awesome; I mean, I don’t rellay need it to be perfect at once. I was just wondering if I needed to open some “strange ports” (for example, with matrix I need to open 2 ports at once to let the federation work). But as long as I’m reachable from others lemmy istances and vice versa, it’s all ok. Thanks for your feedback guys :)

Thanks Matt, apparently I was able at least to federate with lemmy.world since I got your answer… now I “just” have to figure out why I cannot find my user from mastodon (and why if I DM from lemmy my mastodon’s user, I get nothing) :)
