我在尝试在我的计算机上启动非特权 LXC 容器时遇到了一些问题。
$ lsb_release -a

Distributor ID: Ubuntu
Description: Ubuntu 14.04.3 LTS

我已将其放入我的用户的 cron 中，使用crontab -e：
@reboot lxc-start --daemon --name apache --logfile=/tmp/lxc-apache.log --logpriority=DEBUG
然后，我重新启动了机器，并得到了以下信息/tmp/lxc-apache.log：

我应该怎么做才能让我的非特权容器在机器启动时启动？请注意，此问题仅与启动时的容器有关；如果我登录，我的所有非特权容器都会按预期工作。
答案1
万一其他人遇到同样的问题，我的解决方案是：
似乎 cron 没有使用完整的 shell 登录，没有设置所有变量，其中包括 cgroup 相关环境。因此，当 cron 尝试启动容器时，它会失败。
我发现解决我的问题的唯一办法是 ssh 进入同一台机器，然后启动容器。如下所示：
$ ssh-keygen -t rsa
$ ssh-copy-id localhost
之后，我将其放入我的 crontab 中：
@reboot sleep 5 && ssh -l eduar localhost lxc-autostart
