The Terraform API gateway module facilitates the implementation of Kong using infrastructure as code (IaC) while adhering to DevOps best practices, leveraging Terraform's declarative approach. This module, maintained by Kong, serves as a reference platform for setting up Kong Gateway and Kong Enterprise quickly, particularly for demos and proof of concept environments, but it can also be extended for production needs. The process involves defining a Terraform provider for AWS, configuring the necessary prerequisites like VPC subnets and certificates, and using Terraform commands to provision and manage resources while maintaining statefulness for updates. Security practices are emphasized, including the use of AWS S3 for encrypted state storage and the AWS Systems Manager Parameter Store for sensitive data management. Additional configurations are conducted using EC2, Cloud-init, and IAM roles to ensure secure and efficient deployment and management of Kong instances, including features like auto-scaling, health checks, and API configuration.
