How to Use Gcloud Container Operations List API: A Step-by-Step Example

In the era of cloud technology and containerization, managing your services efficiently is paramount. Google Cloud Platform (GCP) provides powerful tools to help you manage your containerized applications. Among these tools is the Gcloud Container Operations List API, which allows developers to query operations associated with Kubernetes clusters and container management. This tutorial will guide you through using this API step by step, integrating it with AI Gateway, Kong, and showcasing its usage in practical scenarios.

Understanding Gcloud Container Operations API

Before diving into the step-by-step guide, let’s briefly understand what the Gcloud Container Operations API is. This API is part of Google Kubernetes Engine (GKE) that allows you to interact with and manage operations related to the clusters and their respective containers. With it, you can:

• List operations for different clusters.
• Retrieve details of specific operations.
• Get the status of various operations being performed within the GKE.

This API is particularly helpful in scenarios that require monitoring and managing ongoing operations in a real-time environment.

Advantages of Using Gcloud Container Operations API

1. Real-Time Monitoring: Keep track of your container operations to ensure optimal performance.
2. Error Handling: Quickly identify and resolve issues in your cluster operations.
3. Audit Trails: Maintain logs of all operations for compliance and auditing.
4. Integration: Seamlessly integrate with other Google Cloud services and third-party tools, such as AI Gateway and Kong.

Setting Up Your Environment

Prerequisites

Before you can use the Gcloud Container Operations API, ensure you have the following:

• A Google Cloud account.
• A GKE cluster set up.
• The Google Cloud SDK installed.
• Proper IAM permissions to access GKE resources.

You can install the Google Cloud SDK by running the following command:

curl https://sdk.cloud.google.com | bash

After installation, initialize the SDK:

gcloud init

Configuring Authentication

Open your terminal and authenticate your account:

gcloud auth login

This command will prompt you to log in to your Google account. After successful authentication, set the project for your session:

gcloud config set project YOUR_PROJECT_ID

Replace YOUR_PROJECT_ID with your actual Google Cloud project ID.

Utilizing the Gcloud Container Operations List API

Making an API Call

Now it’s time to make an API call to retrieve your container operations. We will use the gcloud command as follows:

gcloud container operations list --project YOUR_PROJECT_ID --zone YOUR_ZONE --cluster YOUR_CLUSTER_NAME

• YOUR_PROJECT_ID: Your Google Cloud project ID.
• YOUR_ZONE: The Google Cloud zone where your cluster is located, e.g., us-central1-a.
• YOUR_CLUSTER_NAME: The name of your Kubernetes cluster.

Example Command

Here is an example command to illustrate how to list operations in a specific GKE cluster:

gcloud container operations list --project my-gcp-project --zone us-central1-a --cluster my-cluster

Understanding the Output

The command will return a list of operations currently running in the specified cluster. The output will look similar to this:

This table provides valuable information about the type and status of the operations being performed in your cluster.

Utilizing AI Gateway and Kong for API Management

Overview of AI Gateway and Kong Integration

For enhanced API management, developers often turn to AI Gateway and Kong. AI Gateway provides a simple way to create and manage API endpoints while allowing integration with various back-end services and AI models. Kong is an open-source API gateway that offers many features, including rate limiting, logging, and security.

Setting up AI Gateway

To set up AI Gateway for your GCP project, follow these steps:

1. Navigate to the AI Gateway console.
2. Click on “Create API.”
3. Follow the prompts to define your endpoints and their respective back-end services.

Setting up Kong

Follow these steps to set up Kong as your API gateway:

1. Install Kong using Docker:

docker run -d --name kong-database \
  -e "KONG_DATABASE=postgres" \
  -e "POSTGRES_USER=kong" \
  -e "POSTGRES_PASSWORD=kong" \
  -e "POSTGRES_DB=kong" \
  postgres:9.6

docker run -d --name kong \
  --link kong-database:kong-database \
  -e "KONG_DATABASE=postgres" \
  -e "KONG_PG_HOST=kong-database" \
  -e "KONG_ADMIN_LISTEN=0.0.0.0:8001" \
  -p 8000:8000 \
  -p 8001:8001 \
  kong

1. Configure Kong to route requests to your API endpoints set up in AI Gateway.

AI Gateway and Kong Example

Once you have set up your gateway, you can now create your first API route. Let’s say you want to integrate the Gcloud Container Operations List API with Kong.

Creating a Route in Kong

Run the following command to create a route in Kong:

curl -i -X POST http://localhost:8001/services/ \
--data 'name=container-operations' \
--data 'url=http://YOUR_BACKEND_SERVICE'

Next, let’s create a route for that service:

curl -i -X POST http://localhost:8001/services/container-operations/routes \
--data 'paths[]=/operations'

Making Requests Through Kong

After setting up the route, you can make requests to your API through Kong:

curl -i http://localhost:8000/operations
