Like 1 hour every two months or so, I just run an ansible playbook and check everything is working ok

Yes I use it a lot to read manga and some books. Works perfectly. On Android you can connect with CDisplayEX.

Great summary. How does work the provision with terraform? Do you have some guide? Is possible to provision LXC/VM on proxmox with ansible instead?

Syncthing, Gitea, jellyfin (with arr stack), audiobookshelf, Kavita.

Great starting point! I think option 1 will be better for this scenario. But later if you can, a cheap desktop build will be better for proxmox since you will have more room to expand and play with more things, add more storage even GPU for jellyfin.

Have fun!
