When spinning up the complete example in examples/complete the consul cluster fails to bootstrap with the latest build (3.1.1). If I change the version of alpine-consul back to the previous version 'alpine-consul:3.1.0' things appear to work.
It looks like the dns query is not working in the latest.
@jousby, I'll have a fix for this shortly. It is because of go-dnsmasq. In some environments setcap doesn't work. There is new capability to change the user that go-dnsmasq will run as through ENV variables.

Something else that looks suspect. In the logs for dnsmasq it looks like the service is being continually restarted.
