Launching Instance and Configuring the Webserver Using Ansible:-

Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, intraservice orchestration, and provisioning. 

Task-

Statement - Deploy Webserver on AWS through Ansible!

♦️Provision EC2 instance through ansible.

♦️Retrieve the IP Address of instance using dynamic inventory concept.

♦️Configure the webserver through ansible!

♦️Create a role for the webserver to customize the Instance and deploy the webpage.

Let's Start the Practical Part:-

Step1- First of all, we have to install boto before launching the instance.

pip3 install boto 

Step2- Now, we have to create a role for launching the instance on the top of AWS.

mkdir /etc/myroles

cd /etc/myroles

ansible-galaxy init ec2_role

Step3- Inside the vars/main.yml file, we have to pass AWS Access Key and Secret Key. Provide Access key inside "myuser" variable and Secret key inside "mypass" variable -

vim  vars/main.yml
   
   myuser: XXXXXXXXXXX
   mypass: XXXXXXXXXXX

Step4- Inside ansible config file.

vim /etc/ansible/ansible.cfg

cd

vim ec2.yml

Step5- Now, we have to run the ansible playbook using below command.

ansible-playbook ec2.yml

OUTPUT OF Step5 -

Step6- To get the Instance Ip dynamically in the inventory, we have to download ec2.py and ec2.ini files.

mkdir /mydb

cd /mydb

Inside ec2.py, just change one line => #!/usr/bin/python3

export AWS_REGION='ap-south-1'

export AWS_ACCESS_KEY_ID='XXXXXXXXXXX'


export AWS_SECRET_ACCESS_KEY='XXXXXXXXXXX'

Step7- Now inside the ansible config file, make these changes-

ansible all --list-hosts

Step8- Now, for configuring the webserver inside the EC2 instance -

cd /etc/myroles

ansible-galaxy init Webserver

cd

vim web.yml 

Step9- For running the ansible playbook -

ansible-playbook web.yml

OUTPUT :- Now, on the Browser give the Public IP of the EC2 Instance.

That's All !!
