Install Docker on OS X

brew search docker

There’s too many search results, which one should I choose?

‘boot2docker’ is officially deprecated in favor of ‘docker-machine’

So, Install the following.

brew install docker
brew install docker-machine
brew install Caskroom/cask/virtualbox

Trying to run hello-world

docker run hello-world

I got this error message

* Are you trying to connect to a TLS-enabled daemon without TLS?
