# 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
|
|
```
|
|
|
|
