How to Get Started with Anthos: A Step-by-Step Guide

Are you ready to take your Kubernetes game to the next level? Look no further than Anthos, Google's hybrid and multi-cloud platform that allows you to manage your applications across multiple environments with ease. In this step-by-step guide, we'll walk you through the process of getting started with Anthos, from setting up your environment to deploying your first application. So, let's dive in!

Step 1: Set up your environment

Before you can start using Anthos, you'll need to set up your environment. This includes creating a Google Cloud Platform (GCP) project, enabling the necessary APIs, and installing the Anthos CLI. Don't worry, it's not as complicated as it sounds!

First, create a new GCP project or use an existing one. Next, enable the following APIs in the Cloud Console:

• Kubernetes Engine API
• Cloud Resource Manager API
• Cloud Billing API
• Cloud Build API
• Cloud Storage API

Once you've enabled these APIs, you'll need to install the Anthos CLI. This can be done by running the following command:

curl https://storage.googleapis.com/gke-release/anthos-cli/install.sh | bash

This will install the Anthos CLI on your machine and add it to your PATH.

Step 2: Create a cluster

Now that your environment is set up, it's time to create a cluster. A cluster is a group of virtual machines that run your Kubernetes workloads. With Anthos, you can create clusters across multiple clouds and on-premises environments.

To create a cluster, run the following command:

gcloud container clusters create [CLUSTER_NAME] --zone [ZONE] --num-nodes [NUM_NODES] --enable-stackdriver-kubernetes --enable-ip-alias --machine-type [MACHINE_TYPE]

Replace [CLUSTER_NAME] with the name you want to give your cluster, [ZONE] with the zone you want to create your cluster in (e.g. us-central1-a), [NUM_NODES] with the number of nodes you want in your cluster, and [MACHINE_TYPE] with the machine type you want to use (e.g. n1-standard-2).

This command will create a new cluster in your GCP project with the specified parameters.

Step 3: Connect to your cluster

Now that your cluster is up and running, it's time to connect to it. This can be done using the gcloud command-line tool.

To connect to your cluster, run the following command:

gcloud container clusters get-credentials [CLUSTER_NAME] --zone [ZONE]

Replace [CLUSTER_NAME] and [ZONE] with the name and zone of your cluster, respectively.

This command will download the necessary credentials and configuration files to connect to your cluster.

Step 4: Deploy your first application

With your cluster set up and connected, it's time to deploy your first application. For this example, we'll deploy a simple web application using a Kubernetes deployment.

First, create a new file called web-deployment.yaml with the following contents:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: web
spec:
  replicas: 3
  selector:
    matchLabels:
      app: web
  template:
    metadata:
      labels:
        app: web
    spec:
      containers:
      - name: web
        image: gcr.io/google-samples/hello-app:1.0
        ports:
        - containerPort: 8080

This file defines a Kubernetes deployment with three replicas of a simple web application.

Next, apply the deployment to your cluster using the following command:

kubectl apply -f web-deployment.yaml

This will create the deployment and start the web application on your cluster.

Step 5: Expose your application

Now that your application is running, it's time to expose it to the internet. This can be done using a Kubernetes service.

Create a new file called web-service.yaml with the following contents:

apiVersion: v1
kind: Service
metadata:
  name: web
spec:
  type: LoadBalancer
  ports:
  - port: 80
    targetPort: 8080
  selector:
    app: web

This file defines a Kubernetes service that exposes the web application on port 80.

Apply the service to your cluster using the following command:

kubectl apply -f web-service.yaml

This will create the service and expose your web application to the internet.

Step 6: Verify your application

Finally, it's time to verify that your application is working correctly. To do this, you'll need to find the external IP address of your service.

You can do this by running the following command:

kubectl get service web

This will display the external IP address of your service. Visit this IP address in your web browser to see your application in action!

Conclusion

Congratulations, you've successfully deployed your first application on Anthos! With Anthos, you can manage your applications across multiple clouds and on-premises environments with ease. We hope this step-by-step guide has been helpful in getting you started with Anthos. Happy deploying!
