Docker - airavata

[Pankaj Saha]

Hello Devs,

I am trying to writing a docker script which can create a docker image
based on Ubuntu where airavata (0.15 branch) PGA will be installed and all
related required supporting software will stay installed.

My Dockerfile looks like this:
------------------------------------------------------------------------------------------------------------------------------
#---------- set the base image to Ubuntu
FROM ubuntu

#---------- file Author / Maintainer
MAINTAINER GSoC Pankaj Saha

#---------- update the repository sources list
RUN apt-get update

#---------- setting the work directory as users home
WORKDIR ~/

#---------- installing prerequisites for PGA gateway
RUN apt-get install apache2 -y
RUN sudo apt-get install php5 -y

#---------- installing necessary php extensions
RUN apt-get install unzip -y
RUN apt-get install curl -y
RUN apt-get install openssl -y
RUN apt-get install php5-mcrypt -y

#--------- installing  composer
RUN curl -sS https://getcomposer.org/installer | php
RUN mv composer.phar /usr/local/bin/composer

#--------- activate mod_rewrite
RUN a2enmod rewrite
RUN service apache2 restart

#--------- modifying the 000default file
#ADD /etc/apache2/sites-available/000-default.conf
/etc/apache2/sites-available/
WORKDIR /etc/apache2/sites-available/
RUN sed -i 's/<\/VirtualHost>/<Directory "\/var\/www"> \n AllowOverride All
\n <\/Directory> \n <\/VirtualHost>/g'  000-defau$
WORKDIR ~/

#--------- installing git
RUN apt-get install git -y

#--------- downloading airavata PGA

RUN git clone https://github.com/apache/airavata-php-gateway.git
/var/www/airavata-php-gateway
WORKDIR /var/www/airavata-php-gateway
RUN git checkout airavata-php-gateway-0.15-release
WORKDIR ~/
#--------- making storage folder writable
RUN chmod -R 777 /var/www/airavata-php-gateway/app/storage
-----------------------------------------------------------------------------------------------------------------------------------

PGA web server should stay alive on default 80 port . Now from the image,
that my Dockerfile is creating, I am creating a running container. I am
facing trouble to check whether my host is able to listen from the default
80 port of the docker container. I am trying to figure it out, but if
anyone has previous experience on this please guide me.

Thanks
Pankaj
