Linux下Docker部署ZTNET流程

### 安装Docker环境
### 将下列代码保存为`docker-compose.yml`文件
```java
version: "3.1"
services:
  postgres:
    image: postgres:15.2-alpine
    container_name: postgres
    restart: unless-stopped
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: ztnet
    volumes:
      - postgres-data:/var/lib/postgresql/data
    networks:
      - app-network

zerotier:
    image: zyclonite/zerotier:1.10.6
    hostname: zerotier
    container_name: zerotier
    restart: unless-stopped
    volumes:
      - zerotier:/var/lib/zerotier-one
    cap_add:
      - NET_ADMIN
      - SYS_ADMIN
    devices:

    environment:
      - ZT_OVERRIDE_LOCAL_CONF=true
      - ZT_ALLOW_MANAGEMENT_FROM=172.31.255.0/29

ztnet:
    image: sinamics/ztnet:latest
    container_name: ztnet
    working_dir: /app
    volumes:
      - zerotier:/var/lib/zerotier-one
    restart: unless-stopped
    ports:
      - 3000:3000
    # - 127.0.0.1:3000:3000  <--- Use / Uncomment this line to restrict access to localhost only
    environment:
      POSTGRES_HOST: postgres
      POSTGRES_PORT: 5432
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: ztnet
      NEXTAUTH_URL: "http://localhost:3000"
      NEXTAUTH_SECRET: "random_secret"
    networks:
      - app-network
    links:
      - postgres
    depends_on:
      - postgres
      - zerotier
volumes:
  zerotier:
  postgres-data:

networks:
  app-network:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 172.31.255.0/29
```

### 进入`docker-compose.yml`文件目录，用运行下列命令
```java
docker-compose up -d
```
> ### 报错处理
#### 1.安装报错

```
以上报错是因为，在启动docker的时候防火墙做了策略。如果容器在运行中，停止防火墙，在操作容器就会报这个错误，我们可以重启docker解决此问题
```java
systemctl restart docker.service
```
```
docker-compose up -d 
```
通过以上命令可以解决
#### 2.进入容器时报错
```java
docker exec -it 容器ID /bin/bash
```
去掉`bash`中`ba`即可解决
```java
docker exec -it 容器ID /bin/sh
```
