weblogic uses the external mapped port inside the container when 7201:7001 docker port mapping is used

Hello, I am starting two WebLogic 12.2.1.4 domains in docker from my docker-compose.yml file. So I am starting 4 containers:

• admin-server-A + managed-server-A1
• admin-server-B + managed-server-B1

The following Docker port mapping is used:

• admin-server-A: 7101:7001
• managed-server-A1: 8101:8001
• admin-server-B: 7201:7001
• managed-server-B1: 8201:8001

Everything works fine, except this:

<Feb 12, 2021 5:11:21,002 PM UTC> <Notice> <JMX> <BEA-149535> <JMX Resiliency Activity Server=All Servers : Resolving connection list DomainRuntimeServiceMBean> 
javax.ws.rs.ProcessingException: java.net.ConnectException: Tried all: '1' addresses, but could not connect over HTTP to server: 'localhost', port: '7201'
failed reasons:
 [0] address:'localhost/127.0.0.1',port:'7201' : java.net.ConnectException: Connection refused

The 2nd WL admin server tries to use port 7201 in the container but actually, it is listening on the default 7001 port inside the container. Port 7201 is used from the host machine, and of course, WL is not listening on 7201 inside the container.

Why WL sees and wanna use the host port, instead of use the default 7001?
