• Issue: https://github.com/sonata-nfv/tng-industrial-pilot/issues/29

Scenario

• Hololens used for remote maintenance (via sth like Skype) at Weidmüller
• Connects via an access point to Weidmüller Kubernetes server
• On the server, a VPN client is running as a CNF/Docker container on k8s
• The VPN client connects to the VPN server, which is running on a VM at UPB
• From there, the Hololens can access the Internet

• https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/

Steps:

• Using VM fgcn-tango-vpn as server and CA machine
• Client in Kubernetes can be set up with script copied from here
• Because there is a need for a firewall to be in place access can only be granted with SSH.
• OpenVPN default port is 1194. This needs to be opened by the IMT.
• The server is already set up

One container for connecting VPN and one for receiving glasses data. Can then be connected via localhost inside the pod.???

Steps

1. Build and run the Docker images:

# pull image
docker pull sonatanfv/vnf-proxyvpn:latest
# run in privileged mode to enable tunneling
docker run -d --rm -p 3128:3128 -p 1194:1194 --privileged --name vnf-proxyvpn sonatanfv/vnf-proxyvpn:latest

2. Check the connection using curl with the Proxy:

curl --proxy ??? ifconfig.me

This should show the IP address of the VPN server, which is ???, not your local IP address.

3. Test with Skype
