If you'll let me self promote for a second, this was part of the inspiration for my Ansible Homelab Orchestration project. After dealing with a lot of those projects that practically force you to read through the code to get a working environment, I wanted a way to reproducably spin up my entire homelab should I need to move computers or if my computer dies (both of which have happened, and having a setup like this helped tremendously). So far the ansible playbook supports 117 applications, most of which can be enabled with a single configuration line:

immich_enabled: true
nextcloud_enabled: true

And it will orchestrate all the containers, networks, directories, etc for you with reasonable defaults. All of which can be overwritten, for example to enable extra features like hardware acceleration:

immich_hardware_acceleration: "-cuda"

Or to automatically get a letsencrypt cert and expose the application on a subdomain to the outside world:

immich_available_externally: true

It also comes with scripts and tests to help add your own applications and ensure they work properly

I also spent a lot of time writing the documentation so no one else had to suffer through some of the more complicated applications haha (link)

Edit: I am personally running 74 containers through this setup, complete with backups, automatic ssl cert renewal, and monitoring
