Docker as jenkin Slave.txt

Follow the below steps to configure Docker Remote API to set URL:

Ubuntu:16.0.4

1.vim /lib/systemd/system/docker.service
2.Under this file search for ExecStart and fill as below:
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock
3.Make sure the Docker service notices the modified configuration:
  systemctl daemon-reload
4.Restart the Docker service:
  service docker restart
5.Test that the Docker API is indeed accessible:
   curl http://Prive-IPAddress-of-AWS:4243/version
6.You should see output similar to this as the result:
  {"Version":"17.06.2-ce","ApiVersion":"1.30","MinAPIVersion":"1.12","GitCommit":"cec0b72","GoVersion":"go1.8.3","Os":"linux","Arch":"amd64","KernelVersion":"4.4.0-1035-aws","BuildTime":"2017-09-05T19:59:11.118087934+00:00"}
7.Test using curl
   Note: replace the IP with your Docker host IP
	curl -X GET http://Prive-IPAddress-of-AWS:4243/images/json
