我们正在使用运行alpine linux的docker容器作为bamboo中的构建代理。作为构建计划的一部分，需要创建docker镜像。
我们的构建代理已安装docker，但是我们遇到错误，因为docker守护程序没有运行。使用
启动守护程序/usr/local/bin/dockerd
给出以下内容：
INFO[0000] libcontainerd: new containerd process, pid: 640
ERRO[0001] 'overlay' is not supported over overlayfs
INFO[0001] Graph migration to content-addressability took 0.00 seconds
INFO[0001] Loading containers: start.

为了试图绕过这个，我已经安装了iptables。现在，当我尝试运行docker守护进程时，我得到：
INFO[0000] libcontainerd: new containerd process, pid: 705
ERRO[0001] 'overlay' is not supported over overlayfs

Perhaps iptables or your kernel needs to be upgraded.
(exit status 3)
我现在有点困在哪里，因为sudo不是高山上的事情。
