How do I manage AWS API Gateway with OpenAPI using Pulumi?

In this guide, we will demonstrate how to manage AWS API Gateway using OpenAPI specifications with Pulumi. We will import an OpenAPI specification to create an API Gateway REST API and export the API specification. This allows you to manage your API definitions and configurations efficiently.

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Define the OpenAPI specification
const openApiSpec = {
    openapi: "3.0.1",
    info: {
        title: "Example API",
        version: "1.0.0"
    },
    paths: {
        "/example": {
            get: {
                responses: {
                    "200": {
                        description: "Successful response"
                    }
                }
            }
        }
    }
};

// Create an API Gateway REST API using the OpenAPI specification
const api = new aws.apigateway.RestApi("exampleApi", {
    body: JSON.stringify(openApiSpec)
});

// Export the API ID and the endpoint URL
export const apiId = api.id;
export const apiEndpoint = pulumi.interpolate`${api.executionArn}/*`;

Key Points

• OpenAPI Specification: We define the OpenAPI specification in JSON format.
• API Gateway REST API: We create an API Gateway REST API using the OpenAPI specification.
• Exports: We export the API ID and the endpoint URL for use in other parts of your infrastructure.

Summary

In this guide, we managed AWS API Gateway using OpenAPI specifications with Pulumi. We defined an OpenAPI specification, created an API Gateway REST API using this specification, and exported the API ID and endpoint URL. This approach allows you to manage your API definitions and configurations efficiently using infrastructure as code.
