- disc.host() - returns the hostname or ip
- disc.port() - returns the port
- disc.host_port() - returns (\<host>:\<port>)
- disc.proto_host() - returns (\<proto>://\<host>)
- disc.url() - returns the url (\<proto>://\<host>:\<port>)
Install and import
npm install --save clever-discovery
discovery = require "clever-discovery"
Examples
disc_gearman = discovery("gearman-admin", "http")
try gearman_url = disc_gearman.url() catch err then cb(err)
disc_systemic = discovery("systemic", "thrift")
try systemic_host = disc_systemic.host() catch err then cb(err)
try systemic_port = disc_systemic.port() catch err then cb(err)
To see what interfaces a Clever service exposes, check its launch yaml. You should see one or more exposes listed, and the name
of the expose is used as the interface
value in the discovery client.
