Docker for Mac’s current implementation of osxfs is incredibly slow if you are mounting volumes.

This is our work around:

thanks. i try it, but it is not comfortableю So decide move to docker-machine for now.

Our team has developed a GO app that manages docker-machine and provides a solid developer toolkit across mac, windows and linux:

The primary goals of docker-workbench are;

  • To make it easy to create Docker machines in VirtualBox with sensible defaults (CPUs, disk size, RAM, etc)
  • To make it easy to run multiple containerised web applications without managing DNS, hosts files or ports
  • To provide a standard /workbench shared folder to allow docker-compose volumes work the same for multiple users, cross-platform
  • To allow mobile, tablet and other network devices to easily access the containerised applications

Enjoy!

Upgrade to the latest beta, and make sure you perform a “reset to factory defaults”.

That will get you overlayfs2 which should speed things up.
