    这是一个创建于 3365 天前的主题,其中的信息可能已经有所发展或是发生改变。

    每个应用都是这么提示: WARNING: Your kernel does not support memory swappiness capabilities, memory swappiness discarded.

    搜到了这个解决方案:

    Adjust memory and swap accounting
    When users run Docker, they may see these messages when working with an image:

    WARNING: Your kernel does not support cgroup swap limit. WARNING: Your
    kernel does not support swap limit capabilities. Limitation discarded.
    To prevent these messages, enable memory and swap accounting on your system. To enable these on system using GNU GRUB (GNU GRand Unified Bootloader ), do the following.

    Log into Ubuntu as a user with sudo privileges.

    Edit the /etc/default/grub file.

    Set the GRUB_CMDLINE_LINUX value as follows:

    GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"
    Save and close the file.

    Update GRUB.

    $ sudo update-grub
    Reboot your system.

    貌似不可行啊

    看一下这个: https://wiki.debian.org/LXC
    /etc/fstab
    cgroup /sys/fs/cgroup cgroup defaults 0 0

    GRUB_CMDLINE_LINUX="cgroup_enable=memory" in /etc/default/grub and running update-grub2.

    我用的 docker 1.8.2 好像是能成功建立了,没有 warning 了。
