Docker Best Practices

Installation in macOS

brew cask install docker

Removing some of the default shared folders can decrease CPU usage (e.g. remove /Volumes and /private).

Check storage with:

docker info |grep Storage

In case of performance problems you can run:

docker run --rm=true -it --privileged --pid=host \
    <image name> /usr/bin/top

See disk space:

docker system df

Remove stopped containers, dangling images, the build cache, and unused networks:

docker system prune
