# Docker Best Practices
## Installation in macOS
```
brew cask install docker
```
### Shared Folders
Removing some of the default shared folders can decrease CPU usage (e.g. remove `/Volumes` and `/private`).
Check storage with:
```
$ docker info |grep Storage
```
### Performance
In case of performance problems you can run:
```
docker run --rm=true -it --privileged --pid=host \
<image name> /usr/bin/top
```
### Cleaning Up
See disk space:
```
docker system df
```
Remove stopped containers, dangling images, the build cache, and unused networks:
```
docker system prune
```
