“java.net.NoRouteToHostException: No route to host” between two Docker Containers

Question

Note: Question is related to Bluemix docker support.

I am trying to connect two different Docker Containers deployed in Bluemix. I am getting the exception:

 java.net.NoRouteToHostException: No route to host

when I try such connection (Java EE app running on Liberty trying to access MySQL). I tried using both private and public IPs of MySQL Docker Container.

The point is that I am able to access MySQL Docker Container from outside Bluemix. So the IP, port, and MySQL itself are ok.

It seems something related to the internal networking of Docker Container support within Bluemix. If I try to access from inside Bluemix it fails, if I do from outside it works. Any help?

UPDATE: I continued investigating as you can see in comments, and it seems a timing issue. I mean, it seems once containers are up and running, there is some connectivity work still undone. If I am able to wait around 1 minute, before trying the connection it works.

创建容器后开始联网的经验应该是60秒。
