Problem description Testcontainers can be used from inside a container, this is very useful for different CI scenarios like running everything in containers on Jenkins. When starting the Pravega container with the testcontainer when running tests, client is not able to connect to the segment store uri, because of the publishing IP not configured.

Problem location PravegaContainer

Suggestions for an improvement Adding HOST_IP environment variable.
