docker 在已经启动的容器中开启端口映射

#### docker 在已经启动的容器中开启端口映射

-   [1\. 老办法就是打包再启动](https://blog.csdn.net/MrTreebook/article/details/131661396#1__1)
-   [2\. 修改配置文件](https://blog.csdn.net/MrTreebook/article/details/131661396#2__2)
-   -   [2.1. 先关闭已经启动的所有容器](https://blog.csdn.net/MrTreebook/article/details/131661396#21__3)
    -   [2.2. 关闭docker服务](https://blog.csdn.net/MrTreebook/article/details/131661396#22_docker_7)
    -   [2.3. 找到docker配置文件](https://blog.csdn.net/MrTreebook/article/details/131661396#23_docker_12)
    -   [2.4. 修改hostconfig.json 和 config.v2.json](https://blog.csdn.net/MrTreebook/article/details/131661396#24_hostconfigjson__configv2json_20)

## 1\. 老办法就是打包再启动

## 2\. 修改配置文件

### 2.1. 先关闭已经启动的所有容器

```
docker stop [ID/Name]
```

### 2.2. 关闭docker服务

```
systemctl stop docker
systemctl stop docket.socket
```

### 2.3. 找到docker配置文件

```
cd /var/lib/docker/containors/your_containor_id
```

在找这个ID的时候要先在之前docker没关闭之前查看

```
docker ps -a
```

### 2.4. 修改hostconfig.json 和 config.v2.json

配置文件如下

-   这个是hostconfig.json
-   在这里要把映射的端口信息写入

```

## 3\. 重启docker服务

```
systemctl start docker
```

## 4\. 查看容器端口映射

```
docker start [your_containor_id/name]
docker post [your_containor_id/name]
docker ps -a
```

在本机查看一下[端口占用](https://so.csdn.net/so/search?q=%E7%AB%AF%E5%8F%A3%E5%8D%A0%E7%94%A8&spm=1001.2101.3001.7020)

```
lsof -i:22
lsof -i:80
lsof -i:443
lsof -i:10086
```
