/**
|
||
|
|
* The virtual relays the container serves, and the only place their names are written down.
|
||
|
|
*
|
||
|
|
* zooid is multi-tenant: it binds a config to a Host header and serves any number of them from one
|
||
|
|
* process, so a second space costs a toml in docker/config and nothing else. The names are a union
|
||
|
|
* rather than a string so that a scenario naming a relay that has no config fails to compile
|
||
|
|
* instead of hanging on a 404 from the dispatcher.
|
||
|
|
*
|
||
|
|
* Each host is a name that resolves nowhere. The container is reached on loopback and told what to
|
||
|
|
* call itself, so that what it calls itself is a url a relay selection will keep — see transport.ts
|
||
|
|
* for why that matters, and `.test` is reserved by rfc 2606, so a url that escapes this process
|
||
|
|
* fails to connect rather than reaching a host.
