VPN ​

Your Kubernetes cluster is not accessible to the internet. If you want to deploy and manage applications in your cluster, you need to use the VPN. Each Fed4FIRE user gets an individual VPN configuration. Do not share this config with other users.

Note: each cluster has an internal and external network. The VPN gives you access to the external network of the cluster. Pods running inside of Kubernetes are only accessible from the internal network by default.

You can download the VPN config file from the CloudNativeLab user interface. After downloading the config file, follow these tutorials to connect your computer to the VPN.

sudo apt install network-manager-openvpn-gnome

After adding this, reboot your computer. After rebooting, you can add the VPN using Settings.
