Step 1: Install the Required Packages

To install the required packages, you will need to run the following command:

apt update && apt install wireguard

This command will update the package list and install the WireGuard package.

Step 2: Create a New LXC Container

To create a new LXC container, you will need to run the following command:

lxc launch images:ubuntu/20.04 mywireguard

This command will create a new LXC container based on the Ubuntu 20.04 image and name it "mywireguard".

Step 3: Configure the LXC Container

To configure the LXC container, you will need to run the following command:

lxc config set mywireguard raw.lxc_path /var/lib/lxc/mywireguard/rootfs

This command will set the raw LXC path for the container.

Step 4: Install WireGuard on the LXC Container

To install WireGuard on the LXC container, you will need to run the following command:

lxc exec mywireguard -- apt update && lxc exec mywireguard -- apt install wireguard

This command will update the package list and install WireGuard on the LXC container.

Step 5: Configure WireGuard on the LXC Container

To configure WireGuard on the LXC container, you will need to run the following command:

lxc exec mywireguard -- wg genkey | tee /etc/wireguard/private.key

This command will generate a new private key for WireGuard.

Step 6: Configure the WireGuard Interface

To configure the WireGuard interface, you will need to run the following command:

lxc exec mywireguard -- echo "[Interface]" >> /etc/wireguard/wg0.conf
lxc exec mywireguard -- echo "  ListenPort = 51820" >> /etc/wireguard/wg0.conf
lxc exec mywireguard -- echo "  PrivateKey = /etc/wireguard/private.key" >> /etc/wireguard/wg0.conf

This command will configure the WireGuard interface.

Step 7: Start the WireGuard Service

To start the WireGuard service, you will need to run the following command:

lxc exec mywireguard -- systemctl start wg-quick@wg0

This command will start the WireGuard service.

Troubleshooting

If you encounter any issues during the setup process, you can try the following troubleshooting steps:

  • Check the WireGuard logs to see if there are any errors: lxc exec mywireguard -- journalctl -u wg-quick@wg0
  • Check the LXC container logs to see if there are any errors: lxc exec mywireguard -- journalctl
  • Try restarting the WireGuard service: lxc exec mywireguard -- systemctl restart wg-quick@wg0
