虚拟机拓扑图

Docker Cloud 或者 Docker Compose v2:

|---- container_a1
                                    |----- service_a ----- |---- container_a2
                                    |   (virtual host a)   |---- container_a3
internet --- dockercloud/haproxy--- |
                                    |                      |---- container_b1
                                    |----- service_b ----- |---- container_b2
                                        (virtual host b)   |---- container_b3
