docker containers doesn't communicate or talking to each other.

Hi Experts,

I am attaching both dockerfiles for your reference.

I had exposed port 80 on both the docker files but the application is running on only 8008 and 8009 not on port 80.  Do I need to configure http proxy? My application is not running on port 80.  I dont know why it is not running on port 80 as expose port 80 is there in both the docker files.   Please find below the docker network bridge details

Hi,

       I have a demo machine which is running on port 80.  It is created by the previous employee.  IIIF Image server is third-party application. It is not developed by us.  
This demo machine downloads all docker components from aws, It is running on ubuntu os.  it has nginx included with ntdl component. the demo machine uses separate dockerfiles for both the components. It is running on port 80.  does nginx does anything to run both the components at port 80.  Then What I have to do to make it run.   Please help me in resolving this issue.

With Many thanks,
