# The main differences between this docker-compose.yml and the root
# docker-compose.yml are listed below.
#
# * Instead of modifying the default bridge network as in root
#   docker-compose.yml, we create a new network, wg_web_api_network.
# * Added the "wg" service, running the lscr.io/linuxserver/wireguard image.
#     * It's configured as a basic "server" setup with 3 peers.
#     * Make sure it's added to the wg_web_api_network.
#     * Apart from the WireGuard port, the wg-api port is published as well.
# * The "web" service is unchanged.
# * The "api" service requires a few changes.
#     * Instead of the host network mode, the "api" service runs in the wg's
#       networking namespace. This allows is to have access to wg's WireGuard
#       device.
#     * The --listen argument is 0.0.0.0:1234 instead of 192.168.177.1:1234.
