hostserver-gcp

Overview ¶

Command hostserver-gcp is a combined DirServer and StoreServer that serves a synthetic Upspin tree used to configure sub-domains under the domain upspin.services. Each Upspin user can set the IP address of one sub-domain, the name of which is a hash of their user name.

Assuming the server is running as [email protected], here's how the user [email protected] would configure their sub-domain:

$ upspin mkdir [email protected]/[email protected]/127.0.0.1

If that command succeeds, their host name was created or updated. (This can be any command that performs a DirServer.Put to that path; the put command would work, but mkdir is the simpliest choice in this case.)

To find the host name, the user issues a get request, which returns both the host name and configured IP address:

$ upspin get [email protected]/[email protected]
127.0.0.1
