Consistently out of disk space in docker beta

Docker Desktop
36

Ouch, I haven’t even created or deployed a container and this ran away with all of my free disk space within about a week. Steps to reproduce:

  1. Install Docker for Mac Beta Version 1.11.1-beta13 (build: 7975)
  2. Provide an administrative password to complete setup.
  3. Wonder why the fan is constantly running until the system runs out of space.

The major offenders appear to be the following files:

60G ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2
70G ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/log/dmesg
31G ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/log/docker.log

I assumed the fan was related to corporate antivirus or my VMware virtual machines and didn’t even think to check the Docker beta I’d just installed. The moment I ran out of disk space and VMware notified me my virtual machines were stopping I rushed to track down the culprit.
