No luck getting my Lemmy instance up and running, is this a good place to get some help? (lemmy.world)

I'm not exactly a linux beginner but I'm far from an expert and I could use some pointers. I have a domain and a VPS through Namecheap, I chose Ubuntu 20.04 LAMP and I've tried several guides to get this working but something always goes wrong sooner or later.

My latest attempt is to follow along with this guide: https://join-lemmy.org/docs/administration/install_docker.html

No errors until the docker-compose up -d command, then

ERROR: yaml.constructor.ConstructorError: while constructing a mapping in "./docker-compose.yml", line 26, column 12 found unhashable key in "./docker-compose.yml", line 26, column 13

which leads to image: {{ lemmy_docker_image }}

I guess I could start over with a different guide but I'm just chasing my tail at this point. Could any kind soul suggest where to go from here?

I skimmed the guide you sent and the top says that the portions in brackets are placeholders and need to be replaced with real values. If you change {{ lemmy_docker_image }} to be the name of the image to use dessalines/lemmy:0.18.0 for example, do you get further

[–] [email protected] 2 points 1 year ago (2 children)

I didn't do that because I'm apparently a moron :)

I'm trying with

dessalines/lemmy:0.18.0 dessalines/lemmy-ui:0.18.0

In this section

  # actual and only port facing any connection from outside
  # Note, change the left number if port 1236 is already in use on your system
  # You could use port 80 if you won't use a reverse proxy
  - "80:8536"

this fails with Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use

I tried 8080 instead and got no errors but I wasn't able to load the Lemmy page.

I can now get the "Apache2 Ubuntu Default Page - It works!" So that's something.

In your post you said you installed Ubuntu with a LAMP stack. Do you plan on using Apache as the reverse proxy for your instance?

When you switched ports to 8080 did you add it onto the url? e.g. http://localhost:8080
