在Windows子系统Linux上运行Ubuntu上的Docker

我试图在WSL上运行Docker失败.我已按照install Docker on Ubuntu给出的步骤在WSL上安装了Docker但是当我执行docker ps时出现以下错误：

docker ps    
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

看着码头日志我发现了这个：

level=warning msg="Running modprobe nf_nat failed with message: `modprobe: ERROR: ../libkmod/libkmod.c:586 kmod_search_moddep() could not open moddep file '/lib/modules/4.4.0-43-Microsoft/modules.dep.bin'nmodprobe: WARNING: Module nf_nat not found in directory /lib/modules/4.4.0-43-Microsoft`,error: exit status 1"

Perhaps iptables or your kernel needs to be upgraded.
