Day 55: Understanding Configuration Management with Ansible 🛠️

Are you ready to dive into the world of configuration management with Ansible? Let's unravel the magic of this powerful automation tool and explore its capabilities together!

What's this Ansible?

Ansible is more than just an open-source automation tool; it's a game-changer for IT operations. Whether it's configuration management, application deployment, orchestration, or provisioning, Ansible simplifies complex tasks and streamlines workflows with its intuitive and agentless approach.

Task 01: Installation of Ansible on AWS EC2 (Master Node)

1. Update Package Repository: Begin by updating the package repository to ensure you have the latest package information.

   sudo apt-get update

2. Add Ansible Repository: Add the Ansible repository to your system using the apt-add-repository command.

   sudo apt-add-repository ppa:ansible/ansible

   

3. Update Package Repository: Once the repository is added, update the package repository again to include the Ansible packages.

   sudo apt-get update

4. Install Ansible: Finally, install Ansible on your AWS EC2 instance using the apt install command.

   sudo apt-get install ansible

   

Task 02: Exploring the Hosts File

1. Open Hosts File: Use a text editor like nano to open the Ansible hosts file located at /etc/ansible/hosts.

   sudo nano /etc/ansible/hosts

   

2. View Host Inventory: Explore the host inventory using the ansible-inventory command to list all configured hosts.

   ansible-inventory --list -y

   

Task 03: Setting Up Additional EC2 Instances

1. Create Additional EC2 Instances: Set up two more EC2 instances on AWS, ensuring they have the same private keys as the previous instance (Node).

2. Copy Private Key: Copy the private key of the EC2 instances to the master server where Ansible is set up, ensuring secure communication between Ansible and the nodes.

3. Test Ansible Connectivity: Use Ansible to perform a ping command to the newly set up nodes to verify connectivity and configuration.

   ansible <node-name> -m ping

   

By completing these tasks, you'll gain a deeper understanding of Ansible and its role in configuration management.
