Configuration Management

The goal of this project is to demonstrate how to use ansible to help us configure software.

Here I have created 2 ansible playbooks that can be used to:

Playbook 1 (Playbook Ansible.yml):

  • Setup: Install the following items:

    • Install node.js
    • Install forever
    • Pull/clone git repo
    • Install npm packages
  • Run Tasks :

    • Run app: forever start main.js
    • Security: Ensures bash, openssl, openssh-client, and openssh-server are running latest version.
    • Cleanup: Remove content in /tmp/*

Screencast : This screencast shows how to perform the whole setup, run the defined tasks and the running app.


Playbook 2 (Playbook AWS EC2.yml):

  • Provision: A new virtual machine from a virtual machine provider Amazon EC2 is provisioned.

Screencast: This screencast shows how to perform provisioning of an Amazon Web Services EC2 instance.


Locally I have created two Vagrant Machines following these steps

Creating Virtual Machine

Install vagrant.

You will also need a virtual machine provider. VirtualBox is a recommended provider.

Initialize a virtual machine. ubuntu/trusty64 is one default image. A list of other virtual machine images can be found here.

vagrant init ubuntu/trusty64

Start up the virtual machine.

vagrant up

Then

vagrant ssh

You should be able to connect to the machine.

Configuration with Ansible

Ansible is a tool for configuring and coordinating software on multiple machines. In general, Ansible (like Salt, Chef, and Puppet), use a central server that controls other nodes. Unlike the other tools, Ansible does not require a client service to run on the nodes.

Let's setup some stuff first

We want to create a master server that runs Ansible. First, use a binary package manager to setup some basic stuff missing.

sudo apt-get update
sudo apt-get -y install git make vim python-dev python-pip libffi-dev libssl-dev libxml2-dev libxslt1-dev libjpeg8-dev zlib1g-dev

Now get ansible itself.

sudo pip install ansible

Test ansible

ansible all -m ping

Note, you should not expect to see anything working, quite yet, this just makes sure, python, etc. is setup properly.


You can’t perform that action at this time.
