## 檢查加速器是否生效
命令行執行`docker info`，如果從結果中看到了如下內容，說明配置成功。
```
Registry Mirrors:
[...]
https://registry.docker-cn.com/
```
### 查看容器
```
docker ps -a
```
### 停止容器
```
docker stop 容器ID ## 上圖的有一串字符串的就是容器ID
```
### 刪除容器
```
docker rm 容器ID ## 需要先停止容器，才能進行刪除
```
### 查看鏡像
```
docker images
```
### 刪除鏡像
```
docker rmi 鏡像ID ## 和刪除容器操作差不多
```
