Started using docker at work again.

All the previous work is almost outdated and the old scripts are broken.Been getting issues all over the places.

Normally, I connect remotely over VPN using Cisco's AnyConnect Client.

Big one is not being able to connect to the docker-machine (on windows) while connected work's corporate network.`docker-compose` cannot connect to the docker containers.Error message is similar to:

I need to create a docker based solution in order to connect to a remote host via VPN. The only way in macOS seems creating a virtual machine acting as gateway to the VPN. MacOS - VM + docker daemon - VPN Starting from this example. VPN Passthrough 🔗 Docker Desktop for Mac’s networking can work when attached to a VPN. To do this, Docker Desktop for Mac intercepts traffic from the containers and injects it into Mac as if it originated from the Docker application. The host.docker.internal and vm.docker.internal DNS entries now resolve. We removed hard-coded IP addresses: it now dynamically discovers the IP allocated by macOS. Osxfs file sharing now works. We made a configuration change that should improve disk performance. The Restart option in the Docker menu works.

This machine has been allocated an IP address, but Docker Machine could not reach it successfully.SSH for the machine should still work, but connecting to exposed ports, such as the Docker daemon port (usually <ip>:2376), may not work properly.You may need to add the route manually, or use another related workaround.This could be due to a VPN, proxy, or host file configuration issue.

Only solution I found that works is to port-forward then explicily set the DOCKER_HOST.This causes cert issues that can be overcome with env vars.

Using `docker-compose` to manage the containers, I couldn't get `–tls-verify` to do anything.

VBoxManage modifyvm 'default' –natpf1 'docker,tcp,2376,2376'

Access the WebUI¶

But what's going on? My http://my-host:9091 isn't responding?This is because the VPN is active, and since docker is running in a different ip range than your client the responseto your request will be treated as 'non-local' traffic and therefore be routed out through the VPN interface.

How to fix this¶

The container supports the LOCAL_NETWORK environment variable. For instance if your local network uses the IP range 192.168.0.0/24 you would pass -e LOCAL_NETWORK=192.168.0.0/24.

Alternatively you can reverse proxy the traffic through another container, as that container would be in the docker range. There is a reverse proxy being built with the container. You can run it using the command below or have a look in the repository proxy folder for inspiration for your own custom proxy.

Access the RPC¶

You need to add a / to the end of the URL to be able to connect. Example: http://my-host:9091/transmission/rpc/

Controlling Transmission remotely¶

The container exposes /config as a volume. This is the directory where the supplied transmission and OpenVPN credentials will be stored.If you have transmission authentication enabled and want scripts in another container to access andcontrol the transmission-daemon, this can be a handy way to access the credentials.For example, another container may pause or restrict transmission speeds while the server is streaming video.
