Key Configuration Details Environment Variables: - LANG: Supports: en, ua, ru, tr, no, pl, fr, de, ca, es, ko, vi, nl, is, pt, chs, cht, it, th, hi - WG_HOST: Specifies the public IP or DNS name where the WireGuard server can be accessed. - PASSWORD_HASH: Replace <🚨YOUR_ADMIN_PASSWORD_HASH> with a bcrypt password hash for accessing the WG-Easy web interface. - See How to generate a bcrypt hash for instructions on creating the hash. - PORT and WG_PORT: Define the ports for the web interface and WireGuard respectively. - Volumes: Maps a local directory (wg-easy/) to the container's configuration directory (/etc/wireguard). This is where WG-Easy will store its configuration files. - Capabilities (cap_add): NET_ADMIN and SYS_MODULE are necessary for WG-Easy to manage network interfaces and routes effectively within the container. - Sysctls: Settings like net.ipv4.ip_forward enable IP forwarding, which is crucial for routing packets through the VPN.
