Using docker-maven-plugin from two profiles with different ports causes 'port is already allocated' error

[adamretter]

Hi there, maybe I am doing something silly, but I can't see it yet. I have a Maven project that uses two profiles, basically I want to run tests against two different versions of a database (which is a Docker Image). Each profile tries to start the database Docker Image using its own distinct port (10096 and 10097 respectively). I have checked that those ports are not already in use on my system. When I run the profiles manually from the command line each works fine, but when run together I get the following error:

[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.46.0:start (docker-db-api-7-it-start) on project monex: I/O Error: Unable to start container id [0a0eb824aada] : {"message":"failed to set up container networking: driver failed programming external connectivity on endpoint elemental-2 (e63a42680265a7ccc251142192e9b5773e54ec193a3c651878204ecbbd63d4ef): Bind for 0.0.0.0:10097 failed: port is already allocated"} (Internal Server Error: 500) -> [Help 1]

My pom.xml has these significant bits:
