Deploying IGWs using Ansible
In this recipe, we’ll outline how to deploy IGWs to AWS VPCs using Ansible. An IGW serves as the exit point from a VPC to the internet, allowing public-facing resources within the VPC, such as EC2 or RDS instances, to connect to external networks. For a public-facing service, IGWs are essential to provide internet reachability.
To create an IGW, we must specify the VPC it will attach to, which requires the VPC’s unique ID. This ID is obtained during VPC creation and can be saved as a variable for reference in subsequent tasks. We can then use the ec2_vpc_igw module to create the IGW, specifying the target AWS Region, the VPC ID, and any tags we want to assign. While tags are optional, they are highly recommended for automation, as they facilitate resource identification for deployment validation and fact collection in later tasks.
Once deployed, the ec2_vpc_igw module will return various parameters about the IGW, including its unique...
