Example:
srvName := "my-svc.service.consul"
c := clb.NewClb("127.0.0.1", "8600", clb.RoundRobin)
address, err := c.GetAddress(srvName)
if err != nil {
panic(err)
}
fmt.Printf("%s", address.String())
// Output: 0.1.2.3:8001
Development
tests are run against some fixture dns entries I set up on fliglio.com (dig foo.service.fliglio.com SRV
).
make deps
install depsmake test
run all tests
