Ansible Playbook for provisioning a new EC2 in AWS | Create new EC2 instance in AWS cloud using Ansible Playbook

We will learn how to create a simple Ansible Playbook for provisioning a new EC2 instance in AWS cloud. Please follow the below steps in the machine where you have installed Ansible.

Pre-requisites:

• Ansible is installed and Boto is also installed on Ubuntu EC2 instance
• Make sure you create an IAM role with AmazonEC2FullAccess policy and attach the role to EC2 instance.

Steps to create EC2 instance using Ansible:

Login to EC2 instance using Git bash or iTerm/putty where you installed Ansible. Execute the below command:

Create an Inventory file first

sudo mkdir /etc/ansible

Edit Ansible hosts or inventory file

sudo vi /etc/ansible/hosts

Add the below two lines in the end of the file:
[localhost]
local

cd ~
mkdir playbooks  

cd playbooks

Create Ansible playbook

sudo vi create-ec2.yml 
(copy the below content in green color)

edit the create-ec2.yml to make sure you update the key, AMI and region code which is red marked below:

- name: Ansible ec2 launch

  hosts: localhost

  connection: local

  gather_facts: False

  tags: provisioning

  vars:

    keypair: myNov2023Key

    instance_type: t2.small

    instance_name: test-ec2-instance

    image: ami-007855ac798b5175e

    wait: yes

    group: webserver

    region: us-east-1

    security_group: my-jenkins-security-grp1

  tasks:

  - name: configuring security group for the instance

    ec2_group:

        name: "{{ security_group }}"

        description: my-jenkins-security_group

        region: "{{ region }}"

        rules:

            - proto: tcp

              from_port: 22

              to_port: 22

              cidr_ip: 0.0.0.0/0

            - proto: tcp

              from_port: 80

              to_port: 80

              cidr_ip: 0.0.0.0/0

            - proto: tcp

              from_port: 8080

              to_port: 8080

              cidr_ip: 0.0.0.0/0

        rules_egress:

            - proto: all

              cidr_ip: 0.0.0.0/0

  - name: creating ec2 instance

    ec2_instance:

        security_group: "{{ security_group }}"

        name: "{{ instance_name }}"

        key_name: "{{ keypair }}"

        instance_type: "{{ instance_type}}"

        image_id: "{{ image }}"

        region: "{{ region }}"

        wait_timeout: 3

now execute the ansible playbook by
ansible-playbook create_ec2.yml

If everything is good, you should see the new instance created on AWS console. make sure you are able to connect to that instance.

That's it!! That is how you create a new EC2 instance using Ansible.
