Summary

Follow all the steps in the official lemmy documentation to install the server via docker.

run docker compose up -d

error: parsing /home/user/lemmy/docker-compose.yml: yaml: line 32: found character that cannot start any token

line 32 is: 32 │ {% if lemmy_env_vars is defined and lemmy_env_vars|length > 0 %}

Debian 12

[danielkrajnik]

Wait... are these files just copy-pasted from ansible? Are they just dropped "raw" and users are expected to figure out how to edit them on our own? lol, they are... that's what "manual" installation with docker referred to? That's soo lazy... I'm going to try Lemmy-Easy-Deploy

[Nutomic]

Yes this could be clarified in the instructions. Or link to a specific commit for these files to avoid pulling in unexpected changes. Improvements welcome.

[mgamsjager]

So any updates on this?

[Nutomic]

You need to remove those lines manually. Pull request welcome to improve the docs.

[dessalines]

Not the right repo, this one doesn't even have a Dockerfile.

Are you talking about join-lemmy? lemmy-ansible? Which one?

Also this is almost certainly a docker-compose version issue, make sure you're on the most updated version of docker and docker-compose.

[qiancsff]

不是正确的存储库，这个甚至没有 Dockerfile。

你说的是 join-lemmy 吗？lemmy-ansible？哪一个？

此外，这几乎可以肯定是 docker-compose 版本问题，请确保您使用的是 docker 和 docker-compose 的最新版本。

Docker Installation

Download default config files These files contain {{ }} braces for variables, such as passwords and your domain.

Edit them before starting up lemmy for the first time.

The images will likely be: dessalines/lemmy:VERSION and dessalines/lemmy-ui:VERSION

Tracking Issue: For now, using latest is not advisable as changes can break your instance. Make sure you are using a specific version number. This is temporary and will be fixed.

You must be talking about this file. What you have to do is remove the entire first environment block and replace the second block with this:

environment:
- LEMMY_UI_LEMMY_INTERNAL_HOST=lemmy:8536
- LEMMY_UI_LEMMY_EXTERNAL_HOST=your-domain.com
- LEMMY_UI_HTTPS=true

We really need to link a working docker-compose file.

[bat0nas]

Could anybody share a working Lemmy docker-compose and Lemmy config file? Thanks!!!

It's a shame there's still no tutorial which would just work :)

We recently merged this docker-compose.yml file here: https://github.com/LemmyNet/lemmy-docs/blob/main/assets/docker-compose.yml

Thanks @dessalines . Somehow my containers were not able to communicate with each other. I had to add ports for each container in docker compose file. Otherwise nothing worked.

Anyway.. looks like my Lemmy project is up and running. Still many things needs to be tweaked (proxy, pictrs etc.). But the core - is up.

[Nutomic]

You can make a pull request if anything is still missing from the docs. Anyway this issue should be resolved.
