Ansible EC2 Create Instance

Ansible EC2 create instance is a feature in Ansible, an open-source IT automation tool, that allows you to automate the process of creating Amazon EC2 instances. An EC2 instance is a virtual machine that runs in the Amazon Web Services (AWS) Elastic Compute Cloud (EC2) and can be used to host applications or services.

With Ansible EC2 create instance, you can specify the type of EC2 instance to create, the Amazon Machine Image (AMI) to use as the base image for the instance, the key pair to use to connect to the instance, the AWS region to launch the instance in, and other configuration options.

To create an EC2 instance using Ansible, you need to create an Ansible playbook, which is a YAML file that contains a set of instructions that Ansible uses to automate a specific task. The playbook should contain a task that uses the Ansible EC2 module to launch an EC2 instance with the desired configuration.

Here is an example of how you can use Ansible to create an EC2 instance:

• First, you need to install Ansible on your local machine.
• Next, you need to set up an Amazon Web Services (AWS) account and configure your AWS CLI (Command Line Interface) credentials so that Ansible can access your AWS resources.
• Create a new Ansible playbook to create an EC2 instance. A playbook is a YAML file that contains a set of instructions that Ansible uses to automate a specific task. The playbook should contain the following code:

yaml
- name: Create an EC2 instance
  hosts: localhost
  gather_facts: false
  tasks:
  - name: Launch an EC2 instance
    ec2:
      instance_type: t2.micro
      image: ami-0323c3dd2da7fb37d
      key_name: my-key-pair
      wait: true
      region: us-west-2
      vpc_subnet_id: subnet-049df61146f12
      assign_public_ip: yes
    register: ec2

• In the above code, the instance_type parameter specifies the type of EC2 instance to launch. The image parameter specifies the Amazon Machine Image (AMI) to use as the base image for the instance. The key_name parameter specifies the name of the key pair to use to connect to the instance. The wait parameter specifies whether to wait for the instance to be fully launched before moving on to the next task. The region parameter specifies the AWS region to launch the instance in. The vpc_subnet_id parameter specifies the VPC subnet ID to launch the instance in, and the assign_public_ip parameter specifies whether to assign a public IP address to the instance.
• Save the playbook as create_ec2_instance.yml.
• To launch the EC2 instance, run the following command in the terminal:

ansible-playbook create_ec2_instance.yml

• After the playbook is run, Ansible will create the EC2 instance, and you will be able to see the instance in the AWS EC2 console.

In the above example, you can customize the playbook to fit your specific needs by changing the parameters and adding additional tasks as needed. Additionally, you can use Ansible to automate other AWS operations, such as creating an S3 bucket, creating an RDS database, or deploying an application.
