Communication from secondary containers to primary containers in a multi-image configuration job

Hi there,

I currently have a multi-image job, We have 1 primary container(where all the steps run) named primary and 3 secondary containers named A,B,C.

From the primary container I can reach all the secondary containers i.e A,B,C by name(implying the name can be resolved successfully to the correct IP). The secondary containers can all reach each other by name. But I can not reach the primary container from any secondary container by name.

From our use case, this is required based on the setup of our integration tests.

The question is, how can I reach the primary container from any of the secondary containers?
