Add CRIU support to docker-for-mac.
docker run --rm -it --privileged --pid=host boucher/criu-for-mac
Running this image will install CRIU (currently version 3.4) into the virtual machine that powers the underlying docker-for-mac daemon. If you turn on experimental features in the Docker preferences, this will enable checkpoint & restore to work for containers running under docker-for-mac.
