问题
Following instructions in ribbon-consul example I started consul with
consul agent -dev
then in parent folder of this example
mvn verify -Pconsul -Dswarm.consul.url=http://localhost:8500
From what I gather this is the default location of consul, so I also ran it without, only to have the same result. Task eventually starts all services, however fails to register with consul, with output:

This is repeated for every time and event service started. Frontend reports consul service at http://:8300.
Starting main methods from idea with offset will perform fine (tho frontend returns 403:forbidden, but that is an another issue)
Is there something I am missing, because this seems like a pretty simple example to be bugged?
Versions of examples affected are 2017.9.0-SNAPSHOT and 2017.8.1.
回答1:
Consul client exception "Invalid service address" indicates that service is being registered with IP "0.0.0.0". See consul source code
By default, Swarm has default value "0.0.0.0" for "swarm.bind.address" property, which means accepting connections for “all interfaces” to Swarm. It seems that this IP is being used to register service to consul.
Try to specify swarm.bind.address system property in test/pom.xml for every process e.g.
<process>
<artifactId>example-ribbon-consul-time</artifactId>
<properties>
<swarm.http.port>8081</swarm.http.port>
<swarm.bind.address>127.0.0.1</swarm.bind.address>
</properties>
</process>
