Setting Up Ansible Environment

Ansible provides support for managing multiple servers and getting them to a desired state. For packaging OHIE purpose ansible is used as a user management service. Ansible connects using SSH and needs an environment setup.

1. Create a clean environment for your ansible setup

   vagrant init ubuntu/trusty64
   vagrant up && vagrant ssh

2. Create an ssh key for that instance 

   cd ~/.ssh
   ssh-keygen -t rsa -b 4096 -C "maurya@openmrs.org" -f id_rsa

3. Copy the public key to be used for root user while creating a virtual box for ansible to do it's magic. The following is for copying the content into a mac clipboard. (You can still use cat to see the content and copy it over)

   cat id_ansible.pub | pbcopy  

4. Add ansible ppa and update cache and install ansible on that machine

   sudo add-apt-repository ppa:ansible/ansible
   sudo apt-get update
   sudo apt-get install -y ansible

5. Configure ansible hosts file and add your hosts/servers you would like to manage using ansible to this file

   sudo mv /etc/ansible/hosts /etc/ansible/hosts.bak
   sudo vim /etc/ansible/hosts

   Example:

   [test]
   xx.xx.xxx.xxx
   [production]
   example.hello.com

6. Setting up Git

   sudo apt-get install git
   git config --global user.email "youremailid"
   git config --global user.name "youreusername"
   git config --global core.editor "vim"
   git config --global push.default simple
   git --version
