1.docker安装在远程服务器，jenkins安装在本地机，从jenkins中下载了一些docker plugin，但是在配置远程docker URL的时候失败，测试的时候无法连接上去。2.

Docker URL should contain the port, for example:
http://114.215.138.254:2375
Here 2375 is the tcp port that docker monitors, which is not open by default. You need to set it up like this (taking ubuntu as an example)
1. Modify docker configuration file
sudo vim /etc/default/docker
Add the following:
DOCKER_OPTS="-H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock"
2. Restart docker
sudo restart docker
or
sudo service docker restart
2. View docker port
sudo netstat -ltnp | grep docker tcp6 0 0 :::2375 :::* LISTEN 6112/docker
Warning: It is very unsafe to open the tcp port that docker listens to, and you have exposed the IP address of the host, please set up a firewall!
