If you plan on using the –memory flag when creating containers, you may need to enable memory and swap accounting in the Kernel.

  1. Log into the Ubuntu host as a user with sudo privileges.
  2. Edit the /etc/default/grub file. Add or edit the GRUB_CMDLINE_LINUX line to add the following two key-value pairs:
    GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
  3. Save and close the file.
  4. Update GRUB.
    $ sudo update-grub

    If your GRUB configuration file has incorrect syntax, an error occurs. In this case, repeat steps 3 and 4.

    The changes take effect when the system is rebooted.

More detailed information can be found in the Docker Post-Installation Steps for Linux.
