To design, deploy, and manage APIs on cloud services, GCP offers API Gateway, a fully managed service. At Bobcares, with our Google Cloud Platform Support Services, we can handle your GCP issues.

API Gateway In GCP

We can develop, secure, and watch on APIs for Google Cloud serverless back-ends like Cloud Functions, Cloud Run, and App Engine using API Gateway. It provides high performance and scalability. We can also create better applications. We’ll see an example of how to use the Google Cloud API Gateway in this article.

Cloud Endpoints Quickstart Scripts: We can quickly start with Google Cloud Endpoints using these scripts. Before we begin, we have to run some steps. They are:

• Generate a GCP Project.
• Enable billing for the cloud project.
• Then download and install Cloud SDK. It includes the cloud command-line tool.
• Now initialize the SDK.

  gcloud init
• Configure the default project.

  gcloud config set project YOUR-PROJECT-ID

   
• Set up Docker using the command-line utility to sign in to the Container Registry.

  gcloud auth configure-docker

   

The following services are the minimum need of the Endpoints and ESP: Service Management API, Service Control API, and Google Cloud Endpoints. The Google cloud endpoints services deploy command often turns on these needed services. To verify that the needed services are activated:

gcloud services list

Enable the needed services if we don’t see them listed:

gcloud services enable SERVICE_NAME

Use Of API Gateway In GCP

By running the below code, we can push the mocked API to the GCP environment:

mvn -DGOOGLE_PROJECT_ID=<YOUR-PROJECT-ID> clean install

API Documentation

We must always include the description field in the OpenAPI document’s property definitions and other sections as good practice. We can also include multiple lines in the description box, which also supports GitHub Flavored Markdown. For instance, the action that follows generates a bulleted list on a portal’s API homepage:

swagger: "2.0"
info:
  description: "A simple API to help you learn about Cloud Endpoints.

  * item 1

  * item 2"
title: "Endpoints Example"
  version: "1.0.0"
host: "${ENDPOINTS_SERVICE_NAME}"

We must save the files in a Git repository. Then specify the URL to the Git repository on the Settings page of the portal. This is done to display custom documentation in the portal. The service folder’s subfolders allow us to organize related pages into sections and may contain other subfolders. The filenames and folder names are there for navigation.

As an example, the left navigation bar shows Getting Started as a file with the name “Getting Started.md.” We must have a file titled “navigation.yaml” inside the folder with the same name as the Endpoints service. This file explains how the portal’s left navigation bar should display the content.
