Docker 宿主机和容器可以共享同一个su.net吗

Question

I know that using driver host the container would use the same.network namespace but I would like to get something as in "Bridged Mode" of VirtualBox. I mean: that container to be in the same su.net that host but using different namespace. Is that possible?

Answer 1

I had the same issue. I was trying ping to my container (centos) from my host but it wasn't working.

Here is what I did to solve this. I can't guarantee any stability or security so follow this at your own risk.

My Set-Up:
I have 2 different VMs (Ubuntu) running on my Vmware workstation on my host (Windows 10). I configured to use "NAT" for both my VMs.

1. My first ubuntu VM is running with default settings.

2. My second ubuntu VM: is the Docker Host. I've first installed docker on this VM.

3. After docker is successfully installed on the second ubuntu VM, i've configured the following settings:
   a. Create a macvlan docker.network as follows:

   docker.network create -d macvlan -o parent=eno1
   --su.net 192.168.1.0/24
   --gateway 192.168.1.1
   --ip-range 192.168.1.192/27
   --aux-address 'host=192.168.1.223'
   m.net \

note: eno1 is the physical interface on your VM. Also, change the IP settings according to your LAN settings.

4. On the Second VM (Ubuntu docker host) configure the interface to communicate with your docker container:
   ip link add m.net-int link eno1 type macvlan mode bridge

5. After that configure the IP address and bring the interface UP:

ip addr add 192.168.1.223/32 dev mynet-int

ip link set mynet-int up

6. Finally, configure the route to your container

   ip route add 192.168.1.192/27 dev m.net-int

By following these steps I was able to put the container and the host(ubuntu VM) on the same.network. Pings were successful back and forward.
