Create a VPC in AWS using Ansible

These ansible playbook creates a simple VPC. The AWS VPC created will include the following components

1. vpc (vpc_net)
2. subnet (ec2_vpc_subnet)
3. router (ec2_vpc_router_table)
4. internet gateway (ec2_vpc_igw)
5. security group (ec2_group)
6. ec2 instance (ec2)

Prequisites:

• IAM User with the required permission
• Boto installed (Ansible uses the Boto Python library to handle AWS management)

To create a VPC, we have to use the ec2_vpc_net module. We will register the module returned data in the “vpc” variable

We need an IGW so that our public subnet can access the internet. In our subnet, we have set map_public to “YES”. This means instances created in this subnet is associated with a public IP address.

Here, we would need to route the traffic to the IGW via the route table and create a security group.

Create an EC2 Key Pair and an EC2 instance.

Key points:

• if you already have an EC2 key pair, skip the EC2 key pair and update the key_name with the name of the key pair
• exact_count is important! It determines the number of instances is created
• Image ID can be found on AWS Marketplace
