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

   Code Block
   language bash linenumbers true
   vagrant init ubuntu/trusty64 vagrant up && vagrant ssh

2. Create an ssh key for that instance 

   Code Block
   language bash linenumbers true
   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)

   Code Block
   language bash linenumbers true
   cat id_ansible.pub | pbcopy

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

   Code Block
   language bash linenumbers true
   sudo add-apt-repository ppa:ansible/ansible sudo apt-get update sudo apt-get install -y ansible

5. Configure ansible hosts file 

   Code Block
   language bash linenumbers true
   sudo mv /etc/ansible/hosts /etc/ansible/hosts.bak sudo vim /etc/ansible/hosts
