Having upgraded my local install to the Community Edition (stable), I ran into a scenario where I was receiving a confounding "No space left on device error" error.
Interestingly it seems Docker CE for Mac by default has a max-capacity of 64GB only.

We can get around this by replacing the original template with a new one, with a size of our choosing. Be warned though - you will loose all local images.
Create a new "template" image with desired size:
qemu-img create -f qcow2 ~/data.qcow2 120G
where the 120G is my new size. Replace the default docker template/Application/Docker.app/Contents/Resources/moby/data.qcow2
with your brand new~/data.qcow2
(I've saved the original just in case)Copy
~/data.qcow2
to~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2
Unfortunately this will wipe all your docker data. Also, restart docker. Check disk free:
docker run --rm alpine df -h
