## docker-compose.yml

```yaml
version: "3.8"

services:

  server:
    image: vimagick/kcptun
    command:
      --listen :29900
      --target google-public-dns-a.google.com:53
      --crypt aes
      --mode fast
    ports:
      - "29900:29900/udp"
    environment:
      - KCPTUN_KEY=******
    restart: unless-stopped

  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: unless-stopped
```

## Server Setup

```bash
$ docker-compose up -d server
$ docker-compose logs -f server
```

## Client Setup

```bash
$ docker-compose up -d client
$ docker-compose logs -f client
$ dig @127.0.0.1 -p 12948 www.google.com +tcp
```
