    --target google-public-dns-a.google.com:53
    --crypt aes
    --mode fast
  ports:
    - "29900:29900/udp"
  environment:
    - KCPTUN_KEY=******
  restart: always

client:
  image: vimagick/kcptun
  entrypoint: client_linux_amd64
  command:
    --localaddr :12948
    --remoteaddr easypi.pro:29900
    --crypt aes
    --mode fast
  ports:
    - "12948:12948/tcp"
  environment:
    - KCPTUN_KEY=******
  restart: always
```

## Server Setup

$ docker-compose logs -f server
```

## Client Setup
