Waits forever on etcd when using etcd 3.4 #127
Description
With etcd 3.4.7 the expected line "ready to serve client requests" never appears.
Instead it has the following lines:
2020-04-18 23:52:59.873615 I | embed: ready to serve client requests
2020-04-18 23:52:59.875402 N | embed: serving insecure client requests on 127.0.0.1:2379, this is strongly discouraged!
Is there a reason that etcd uses wait_for_line instead of wait_for_port? It seems like the latter would be more stable.
