Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
14: curl#6 – "Could not resolve host: mirrorlist.centos.org; Unknown error"

One of the configured repositories failed (Unknown),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum –disablerepo=<repoid> …

     4. Disable the repository permanently, so yum won’t use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use –enablerepo for temporary usage:

            yum-config-manager –disable <repoid>
        or
            subscription-manager repos –disable=<repoid>

     5. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager –save –setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/7/x86_64

这个砸破

LXC架构，所以不行

cherbim牛人大佬：

你是想euserv的lxc小鸡里装docker么，这个是不行的，因为lxc是基于容器虚拟化，权限不足（好像修改一个参数，才能套娃）
基于内核虚拟化的的比如kvm，xen等才可以使用docker

怎么说才能让你们相信？

不知道绑定

nnt牛人大佬：
猛人，这老母鸡常年负载20+，IO 2.4M/s 也敢装docker，再说这lxc虚拟化也不支持呀

这个连swap和bbr都搞不了

他家lxc没设置docker可用
