关于docker的问题

比比皆是

本人环境是用的windows7开户的ubuntu:16.04容器，容器ufw已经开启，但是在ufw enable开启时提示
ERROR: problem running ufw-init
/lib/ufw/ufw-init: 118: /lib/ufw/ufw-init: modprobe: not found
/lib/ufw/ufw-init: 118: /lib/ufw/ufw-init: modprobe: not found
/lib/ufw/ufw-init: 118: /lib/ufw/ufw-init: modprobe: not found
iptables-restore: line 77 failed

Problem running '/etc/ufw/before.rules'
Problem running '/etc/ufw/user.rules'

1、进入pycharm点击设置settings，搜索docker配置docker
2、在选择TCP socket -> Engine API URL -> 输入tcp:容器ip（etho中的inet addr:ip地址）:2375,连接一直报错，提示如下
Cannot connect:Cannot connect to the Docker daemon at tcp://172.17.0.2:2375,is the docker daemon running?
一直没找到原因，求解
