Dear all,

I do not understand how to manage container network.

Comparing to VMware ESXi host suppose its has 2 ethernet interfaces; ETH0, ETH1.

I will use ETH0 for management and talk to vCenter Server.

For ETH1 I will tagged multiple VLAN to use it for virtual machine connectivities because I don’t want virtual machine and its application use the same subnet.

How do Docker Host manage Network because I do not want all containers use host subnet and expose port?
