Found an OSS timeblocking tool but need help hosting it

Found this tool somewhere on reddit https://github.com/GeneralTask/task-manager/tree/master

This seems like a difficult tool to selfhost. I have hosted few apps earlier but those were direct docker containers.

I see 3 major challenges with this setup:

1. Backend : It creates 2 containers but those are generic DB servers. Would the dockerfile install the actual code ?
2. Frontend : How to connect with backend
3. Fontawesome pro subscription is a requirement

Any help would be appreciated
