Hi Team,

services:
  wireguard:
    image: masipcat/wireguard-go:latest
    cap_add:
     - NET_ADMIN
    sysctls:
     - net.ipv4.ip_forward=1
    volumes:
     - /dev/net/tun:/dev/net/tun
     # Folder with 'publickey', 'privatekey' and 'wg0.conf'
     - ./wireguard:/etc/wireguard
    environment:
     - WG_COLOR_MODE=always
     - LOG_LEVEL=info
    ports:
     - 51820:51820/udp
    # Uncomment the following line when 'AllowedIPs' is '0.0.0.0/0'
    # privileged: true
    restart: always

and run the below command for run the yml file:

docker-compose up -d
