There is just one PieFed running in docker on the Pi. My labeling might be a little confusing there.

I followed the easy instructions up until getting PieFed running in the background then skipped down to the Running PieFed in production section. I didn't see any of the files mentioned in that section and thought to continue from there.

To start, if I load PieFed first, then nginx I get an error like below:

nginx error:

If I do the opposite and load nginx before PieFed, PieFed will make a similar complaint about sharing the same port.

The pyfedi.service, celery.service and celeryd files all look similar to the examples from the INSTALL.md except I changed the directory names to match my name in the appropriate places.

Here are the error messages I am getting from systemctl:

pyfedi.service error/celery.service error:

At this point I am stuck and not sure where to go from here.

You're right, it was outdated. It seems I got mixed up after a fresh OS install on my Pi. I used APT to download and install docker which is extremely outdated. I now have proper repositories set up for both docker and nginx and everything is up to date. I didn't need to make any changes to the dockerfile with the proper version.

I'm having issues getting nginx, pyfedi.service and celery.service to work.

Below are some snippets from my notes which should lay out all the steps I've taken, hopefully that will explain where I am currently at.

I decided to start over today with a fresh OS install on my Pi. I did everything according to a checklist I started so nothing new has changed from my knowledge. I am getting errors trying to get past the

export DOCKER_BUILDKIT=1  
docker-compose up --build  

part of the INSTALL.md for the docker instructions.

I've saved a copy of my terminal but I'm not sure where a good spot to paste it is since it's long. There were a lot of permission error 13's so I tried

sudo docker-compose up --build  

and things started to download and proceed up until a point before another error showed up.

Step 1/14 : FROM --platform=$BUILDPLATFORM python:3-alpine AS builder  
failed to parse platform : "" is an invalid component of "": platform specifier component must match "^[A-Za-z0-9_-]+$": invalid argument  
ERROR: Service 'celery' failed to build : Build failed  

I'm quite confident I did nothing different this time so I don't know what would be causing issues today. I can provide you with the outputs from my terminal if that will help you.

Yeah, I had :5000 at the end, otherwise I would have gotten an error with the initial website connection from a browser saying the domain did not match. That's how I figured out to change the port in the compose.yaml from an earlier attempt.

I did not create a reverse proxy. I got excited at getting the site to load that I missed that. I'll try that in a couple days when I'm free again.

Docker decided to randomly disappear my PieFed image an hour after I finished working on it. The PyFedi folder and all it's contents have vanished. A very quick search showed that it has happened to other people with other images. So it's a thing maybe? Strange but fortunately it was all fresh and nothing was lost.

So after a few attempts, I was able to get PieFed working by accessing it through pi.MyDomainName.ca:5000

I changed the SERVER_NAME in .env.docker to match the address above, but with my actual domain name. I also changed the port numbers from 8030:5000 to 5000:5000 in the compose.yaml

I am running into an issue when I attempt to use the login information after the database initialization steps. I get the error "The CSRF tokens do not match." above the username field on the login screen. I'm not sure what that means exactly.

Other than that, using the docker was fairly straight forward except for some information I forgot to put in correctly the first couple times.

Thanks for the suggestions, I'll have a look into them and see how they fit my needs. I am looking for something that uses markdown language. I'm using that in other parts of this project as a way to keep things unified and simple for others to participate or contribute.

I don't do blogs or anything but I do intend to make a community on slrpnk.net in addition to my local instance on my pi. The Solarpunk community will focus more on creating a guide for others to create their own local communities and knowledge base.

The ultimate goal is making sure it's simple and accessible to as many people as possible.

Once I set up an instance or some sort of community page, I plan to write up an outline of decision choices and future goals in order to help people understand what's going on and where to begin contributing. I'll be able to use my seed library as a working example.

I am hoping to be ready within the next couple weeks. I can let you know when the Solarpunk community goes up so you can check it out.

Thanks for the information.

I have a more questions about account registration/logins. If I understand correctly, they will require SSL.

Before I ask anything, I just want to explain what it is I want to do so it's easier to understand where I'm coming from.

I want to start a seed library for my local community in my town. Unless Monsanto is targeting libraries for heritage seeds, I feel my risk is quite low.

I would like a simple place for people to talk, share information and organize events. I'm also trying to create everything as independent from outside services as possible. The reason being that if any of these outside services experience an extended outage, I can physically move my Raspberry Pi box to central location with local internet/wifi (a library for example) and people will still be able to access all the information. Think of the pi box as becoming a digital community board. In this situation, federation is completely unimportant.

If Cloudflare tunneling experiences issues or outages, can people still create and login to accounts locally? I'm going to assume any disruptions to any email services would also have an effect since that is used for registration as well.

I prefer the Reddit/Lemmy/Piefed style and the markdown language works well with the other parts of my project. It's not necessary and I may keep searching around for something that suites my use case better.

I'll most likely go ahead and try installing PieFed anyways with Cloudflare tunneling(or Let's Encrypt if I don't have to worry about blocked ports) and smtp2go. At the very least it'll be an experience and a good place to start for my needs. I can move on from there if I feel the need to.

Thanks again.
