If you find yourself using an Operating System that doesn’t natively support Docker, then give dvm a spin.
In order to make updates simpler, a Homebrew tap has been setup for dvm at fnichol/hombrew-dvm and the vendored formula has been moved to that repository. The examples below have been updated to reflect this.
As we know, the Docker and Homebrew communities move very fast. Now you can install Docker via Homebrew with
brew tap homebrew/binary ; brew install docker–nice and simple. The examples below have also been updated to reflect this.
Docker is pretty awesome technology and is being used everywhere these days. But what if your workstation du jour is a Mac or another platform that doesn’t yet support running the Docker daemon? In that case, there’s a good chance you’re using and abusing Vagrant on a daily basis–as am I.
As someone who typically uses a Mac for development, I’ve been keeping tabs on several projects over the last month that have finally landed:
After a few hours of very enjoyable hacking I was able to boot the Vagrant base box–with a private network setup no less–and use the
docker binary on my Mac spin up containers. In order to help manage the virtual machine from any directory and deal with future Vagrantfile updates, I cranked out dvm to smooth out any remaining rough edges.
Assuming you have Vagrant and VirtualBox set up, here are the resulting steps to get up and running with dvm on a Mac:
# Install Docker Mac binary (see note below) brew tap homebrew/binary brew install docker # Install dvm brew tap fnichol/dvm brew install dvm # Bring up your Vagrant/Docker VM dvm up # Set a DOCKER_HOST environment variable that points to your VM eval $(dvm env) # Run plain 'ol Docker commands right from your Mac docker run ubuntu cat /etc/lsb-release
--- driver: name: docker socket: tcp://192.168.42.43:4243
or if you prefer to use the
DOCKER_HOST environment variable that dvm provides, try:
--- driver: name: docker socket: <%= ENV['DOCKER_HOST'] %>
