does know how docker decides nic work docker0 network? have node 2 interfaces (eth0 , ens34), however, requests go through eth0 forwarded container. when vm provisioned , docker installed, started silly test: created centos vm, installed netcat on , committed image. started daemon container listening on port 8080. used: docker -it -p 8080:8080 --name nc-server nc-server nc -vv -l 8080 so tried connect container listening on port 8080 node in same network (in same ip address interface ens34). did not work. whereas when sent request machine ip address eth0, saw reaction in container (the communication worked).
