Self host on prem + configure base domain

Heya! Found this tool from looking online. Two questions:

- we are a fully on prem shop and would want to host this in our on-prem Kubernetes cluster. I see there's a docker image. Can I confirm it doesn't require internet access?
- I see the base domain is `s/` - is it possible to change this to `go/`, to make it similar to https://www.golinks.io/?
