RVM, Ruby and Gemstash Installation

This is required to speed up bundle install. RVM Installation is fairly simple for ubuntu systems.

# Refer to https://github.com/rvm/ubuntu_rvm
sudo apt-add-repository -y ppa:rael-gc/rvm
sudo apt-get update
sudo apt-get install rvm

# After this installation ruby 
rvm install 2.4

Design Document

Amahi now supports Docker. It is an open source software for automating the deployment of applications inside software containers. A container image is a lightweight, stand-alone, executable package of a piece of software that includes everything needed to run it: code, runtime, system tools, system libraries, settings.

For more information related to contianers refer to : https://www.docker.com/what-container

The idea was to get/build images of different applications and run them using docker on the hda. The benefit of using containers as opposed to the earlier method is that each container runs in an isolated environment. So they can each have different versions of different applications. For example we can have an app running on php5 and another app running on php7. Using this method if we had an image available for an app then we can directly run it using docker without any problems.

Amahi Documentation

Important Terms

Before going further in this document, understanding the following terms might be useful:

• What is a Container?
• Image vs Container
• amahi.net -> Domain name of the amahi hda for all examples here

Problem Statement

Amahi supports one click install for different kind of apps. To add any app to amahi they have to be packaged properly. Each app might require a completely different environment to run and it might not be possible to provide that environment to every app because their can be dependnecy conflicts. For example some app might require php5 and some might require php7. We need a mechanism to address this concern such that we can add any app to Amahi irrespective of the technology stack that it might require or without version conflicts.

Dependencies Added

docker-api added in Gemfile. For more details on docker-api refer to https://github.com/swipely/docker-api

Modifications in app/models/app.rb

Firstly I added a few lines to make sure that docker.sock had right permissions. I was facing some issues because the process which runs installer doesn't have the permission to write to docker.sock. We tried various fixes but they didn't work and hence shifted to this temporary workaround

        def install_bg
+               # Change permissions of docker.sock file
+               if Rails.env=="production"
