TASK [start docker-compose] : Unable to load docker-compose about lemmy-ansible

[tifriis208]

I just test the new playbook (v1.2.0) on a fresh install on a raspberry pi4 with ubuntu 22.04 64 bit and no more issue with docker, thanks !

[tifriis208]

I try to install ansible-galaxy collection install community.docker but nothing change

[dessalines]

I've never tested this playbook on arm, so you might have to install docker manually on that machine, then skip the docker install steps in the playbook.

[tifriis208]

Thanks for your return. Indeed, the playbook only work for x86_64:

- name: Install or upgrade docker-compose
  get_url: 
    url : "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-Linux-x86_64"

As raspberry pi is officialy supported in the documentation (Supports arm64 / Raspberry Pi), would you accept a pull request to modify this playbook according to official docker documentation?

Thanks

I think this Pull Request should also solve this issue : #62

[dessalines]

Sure.

#62 didn't work when I used a fresh ubuntu install, and no docker installation recommends you use the docker from the ubuntu repos.

I am also seeing this same issue on a new Ubuntu 22.04 server that is not arm64, just regular x86_64.

[dessalines]

Hrm... I'm wondering if the script successfully installed docker on that machine. What does sudo docker info say there?

[jonaharagon]

Can't check right now, but Docker was installed and docker-compose was correctly located in /usr/local/bin.

All I had to do was run pip install docker-compose manually as Ansible suggested to get this working. Not sure why the compose install didn't work since it was downloaded?

[dessalines]

My best guess is that it couldn't complete, because you already had docker installed, through your system repos, and not via the official docker install method.

[jonaharagon]

Probably not, Hetzner Cloud images don't come with Docker installed. I think your process for installing docker-compose is outdated, what it looks like is Ansible is expecting to use docker-compose 2.x on lemmy.yml#L167 (which gets installed to /usr/libexec/docker/cli-plugins/) and you're installing the old 1.x version to /usr/local/bin instead.
