Docker For Mac Vpn Passthrough

 

Networking features in Docker for Mac VPN Passthrough. Docker for Mac’s networking can work when attached to a VPN. Docker for Mac makes whatever is running on port 80 in the container (in this case. HTTP/HTTPS Proxy Support. Following is a summary of current. This is because the VPN is active, and since docker is running in a different ip range than your client the response to your request will be treated as 'non-local' traffic and therefore be routed out through the VPN interface.

I've recently taken to using Docker to install and run various softwareon my home server. Something that so far, it excels at - the people atlinuxserver.io are doing great work! I've had a rocky time with Docker inthe past after having had it foisted upon me for development work, which I didnot enjoy, but I can see the benefits for certain situations.

I found myself needing to run the traffic from one particular container(Jackett) over a VPN connection so that it could by-pass country-specificrestrictions. As a noob Docker user, this caused some confusion, but I eventuallystumbled upon the --net parameter to docker create and run.

Using this parameter it's possible to tell a container to use the network ofanother. You can run an OpenVPN client container, which will initiate a secureconnection, and configure other containers to use its network. The beauty ofthis setup is that you don't need to learn or manage any complicated ip_tablesrules or any other network configuration, you can just point one container atanother and have the traffic secured.

All I needed now was a suitable Docker image. Eventually, I got lucky andfound an image that supported my exact VPN provider, NordVPN.

This is how I created and started the OpenVPN container. Once this was running,a secure VPN connection was established to NordVPN.

Most of these options are standard, but the -p 9117:9117 parameter on line 5needs explanation. This is the port mapping that Jackett uses by default. Whenwe use another container's network it's necessary to expose the port(s) that ourother containers use on the VPN container.

And here is how I setup Jackett to use the VPN container. The relevant line is--net=container:vpn. Note that I don't have a -p 9117:9117 line here like Iwould if I was not using --net=container:vpn.

Now I can access Jackett at http://<host-ip>:9117 and all traffic will be sentthrough the VPN container's network!
