(not a support request)
I made a fork of this lancache repo, and added the ability to define custom DNS entries in the docker config.
Its simple and super jank, but If you really want to for example give your NAS a local DNS name, but don't want to spin up a separate DNS server, you can use this 2 in 1 and save resources.
Sidenote: I didn't make a pull request since I don't think this is a feature that people would usually want, also the implementation is kinda lazy
