For install docker into ubuntu based os

$ sudo apt-get update

$ sudo apt-get install apt-transport-https ca-certificates curl software-properties-common

$ sudo touch /etc/apt/sources.list.d/docker.list &&  sudo nano /etc/apt/sources.list.d/docker.list 

and append this repo 'deb https://apt.dockerproject.org/repo ubuntu-xenial main'

$sudo apt-get update

if any warning of `signature verfication error'
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $(Signature key)

$ sudo usermod -aG docker $USER # for add current user into docker group for sudo permission

========================================
for install image

$ mkdir ubuntuimage && cd ubuntuimage

download `default`, `supervisord.conf`, `Dockerfile`, `start.sh` into corrent directory

give execute permission to start.sh

$ chmod +x start.sh

$ sudo docker build -t nginx_image .

then make a directory where it represent /opt/projects

$ sudo mkdir -p /webroot

$ sudo touch /webroot/info.php

write `<?php phpinfo(); ?>` into /webroot/info.php

$ sudo docker run -d -v /webroot:/opt/projects -p 8080:8080 --name devops nginx_image # here devops is the container name

Now it run into 8080 port

start.sh

/usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf
