Permit Docker service to bind on TCP in order to be contacted remotely (eg. by Jenkins). On Ubuntu Server you must change docker.service file.

vi /etc/systemd/system/multi-user.target.wants/docker.service

...
ExecStart=/usr/bin/docker daemon -H fd:// -H tcp://0.0.0.0:4243
....

systemctl daemon-reload
service docker restart

Build Image

docker build -t jenkinsslv-php5 .
