  • VirtualBox 
    ln: failed to create symbolic link 'symlink': Protocol error

Docker and the security

Docker benchmarking conclusion

  • Using Linux Virtual Machine on Windows
    • Insignificant overhead CPU and Memory
    • The shared between Windows and Linux is the problem:
      • VBoxSF protocol with Boot2Docker (VirtualBox)
      • CIFS protocol with Docker Beta (Hyper-V)
    • Some Linux filesystems features don't work (Symbolic link, Inotify)
  • Native performance on Linux host
