This document describes how to build Bahmni Vagrant Box using packer. Packer is used to build images. Packer installs and configures all the software for a machine at the time the image is built. Packer also has the ability to take the results of a image and turn it into a vagrant box. For more information on packer check https://www.packer.io/intro/index.html

Steps to build the Bahmni vagrant box

1. Install Packer

   packer : https://www.packer.io/intro/getting-started/setup.html

2. Clone bahmni-vagrant repo from GitHub

   Code Block
   git clone https://github.com/Bahmni/bahmni-vagrant.git

3. From with in bahmni-vagrant directory run the below command 

   Code Block
   cd bahmni-vagrant python render_template.py <bahmni_version> <ansible_version> e.g: python render_template.py 0.88 2.2.0.0

   This will create a template.json file inside the packer directory. If the template.json is already there in the packer folder it will create template_rendered.json file.

4. From with in the packer directory run the below command. Before running the below command need to delete one and two set of lines from template_rendoredrendered.json file as it will try to push the box to Atlas and expects the credentials.

   Tip
   As an alternative to manually deleting the Atlas credentials from the JSON template, you can use jq to dynamically remove them before passing this through to the packer build step. Code Block jq '.["post-processors"][0] |= map(select(.type != "atlas"))' template_rendered.json | packer build -

   Once the Atlas credentials are removed you can run this:

   Code Block
   cd packer packer build template_rendered.json

   Once we run the above command, packer will start building the Bahmni Vagrant Box by downloading the CentOS image from remote repository. The entire process will take at least one hour.
