Notes

注意事项

Use
```
docker system df
```
to see disk usage
Use
```
docker system prune
```
for general cleanup
Consider using
```
--restart unless-stopped
```
for production containers
Use volumes for persistent data
Use networks for inter-container communication

使用
```
docker system df
```
查看磁盘使用情况
使用
```
docker system prune
```
进行全面清理
生产环境容器建议使用
```
--restart unless-stopped
```
参数
使用卷存储持久化数据
使用网络实现容器间通信
