I’ve been searching a lot on this topic but I did not find the final answer yet, so I was hoping anyone here could answer my question.
Since we are more and more migrating to Azure, I was hoping I could use an Azure Virtual Machine as my Docker Host. However, I am having troubles accessing containers from outside this VM with internal IP ranges. I know this is possible with Hyper-V (with an internal switch / transparent network) and macaddressspoofing, however this seems not possible on an Azure VM. I tried the described setting as here: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/b09266b0-ac4e-424f-8757-c34547c4adb1/unable-to-ping-containers-created-with-transparent-network-from-other-hosts?forum=windowscontainers but that does not get me what I want.
What I’ve done so far:
- Created an Azure Virtual Network with various subnets
- Created an Azure Virtual Machine based on Windows Server 2016 with Containers image on one of the subnets (for example internal IP range 10.0.2.0 – 10.0.2.255);
- Created an Azure VPN with which you can access the Virtual Machine on it’s internal IP;
- Created an Azure Transparent Network with currently the same subnet / gateway as the Azure VM (ideally this would be a different subnet / IP range);
- Created a Docker Container which I can reach from inside the Azure VM;
What I would like to accomplish:
- I would like to be able to connect to the containers with the internal IP adresses so I don’t have to use all kinds of different port mappings;
- This connection would obviously only work when the VPN connection is established;
a. Container 1: CONTAINER1 – 10.0.10.10;
b. Container 2: CONTAINER2 – 10.0.10.11;
c. Container 3: CONTAINER3 – 10.0.10.12;
e. Establish VPN connection from laptop / work station;
f. Connect to various environments with respective adresses (http://10.0.10.10, 10.0.10.11etc) or even with hostname if I edit local host file.
Any suggestions how to accomplish what I want? Or is this just not possible? I know a possible alternative is to create a Hyper-V VM as Docker Host inside my Azure VM, but that seems a bit overkill plus I am not even sure if my containers would be reachable from outside my Azure VM.
Any help is much appreciated, thank you in advance.
