Complete Guide: Setup Azure Arc Kubernetes on GCP (GKE) & AWS (EKS)

Azure Arc allows you to manage Kubernetes clusters running outside of Azure, including those hosted on Google Cloud (GKE) and Amazon Web Services (EKS). This guide will walk you through setting up and onboarding Kubernetes clusters to Azure Arc on both GCP and AWS.

1. Prerequisites

General Requirements

  • Azure Subscription: You need an active Azure account. Sign up here
  • Azure CLI: Install Azure CLI on your local machine.
  • kubectl: Kubernetes command-line tool.
  • Helm: Helm package manager for Kubernetes.
  • GCP Account: Set up a GCP project and enable Kubernetes Engine.
  • AWS Account: Set up an AWS account with permissions to create EKS clusters.

2. Setting Up Kubernetes on GCP (GKE)

Step 1: Create a GKE Cluster

  1. Authenticate with GCP:
    gcloud auth login
  2. Set project:
    gcloud config set project YOUR_PROJECT_ID
  3. Enable Kubernetes API:
    gcloud services enable container.googleapis.com
  4. Create a GKE cluster:
    gcloud container clusters create gke-cluster \
    --zone us-central1-a \
    --num-nodes 3 \
    --machine-type e2-standard-4
  5. Get cluster credentials:
    gcloud container clusters get-credentials gke-cluster --zone us-central1-a

3. Setting Up Kubernetes on AWS (EKS)

Step 1: Create an EKS Cluster

  1. Install AWS CLI and configure:
    aws configure
  2. Create an EKS cluster:
    eksctl create cluster --name eks-cluster --region us-east-1 --nodes 3
  3. Verify the cluster:
    kubectl get nodes

4. Connecting GKE & EKS to Azure Arc

Step 1: Register Azure Arc Provider

Run the following to register Azure Arc for Kubernetes:

az login
az provider register --namespace Microsoft.Kubernetes
az provider register --namespace Microsoft.KubernetesConfiguration

Step 2: Install Azure Arc CLI Extensions

az extension add --name connectedk8s
az extension add --name k8s-configuration

Step 3: Connect Kubernetes to Azure Arc

For GKE Cluster:

az connectedk8s connect --name gke-cluster --resource-group YOUR_RESOURCE_GROUP --location eastus

For EKS Cluster:

az connectedk8s connect --name eks-cluster --resource-group YOUR_RESOURCE_GROUP --location eastus

Step 4: Verify Connection

az connectedk8s list --resource-group YOUR_RESOURCE_GROUP

5. Deploying Azure Policies & Monitoring

Step 1: Enable Azure Policy for Kubernetes

az k8s-extension create --cluster-type connectedClusters --cluster-name gke-cluster \
   --resource-group YOUR_RESOURCE_GROUP --extension-type Microsoft.PolicyInsights

Step 2: Enable Azure Monitor for Containers

  1. Enable Azure Monitor:
    az monitor log-analytics workspace create --resource-group YOUR_RESOURCE_GROUP --workspace-name arc-logs
  2. Connect monitoring:
    az monitor log-analytics workspace list
az k8s-extension create --cluster-type connectedClusters --cluster-name gke-cluster \
    --resource-group YOUR_RESOURCE_GROUP --extension-type Microsoft.AzureMonitor.Containers

6. Managing and Deploying Applications

You can now use Azure Arc to deploy applications across your Kubernetes clusters using GitOps, policies, and Azure Monitor.

To deploy a sample app:

kubectl create deployment hello-world --image=k8s.gcr.io/echoserver:1.4

Expose the app:

kubectl expose deployment hello-world --type=LoadBalancer --port=80 --target-port=8080

7. Conclusion

You have successfully onboarded GKE and EKS to Azure Arc. Now, you can manage these clusters as if they were Azure-native using Azure Portal, Azure Policy, and Azure Monitor.

Learn Java 8 streams with an example - print odd/even numbers from Array and List

Image
Example 1: Java 8 program to print odd numbers from a List   import java.util.Arrays; import java.util.List; import java.util.stream.Collectors; /*Java 8 Program to find Odd Numbers from a List*/ public class DriverClass { public static void main( String [] args) { List < Integer > numbers = Arrays. asList( 1 , 4 , 8 , 40 , 11 , 22 , 33 , 99 ); List < Integer > oddNumbers = numbers.stream(). filter(o -> o % 2 != 0 ). collect(Collectors.toList()); System.out.println(oddNumbers); } } 1. Initialize List using Arrays.asList() method. Java's built-in Arrays.asList() method converts an array into a list. This method takes an array as an argument and returns a List object. 2.  Java List interface provides stream() method which returns a sequential Stream with list of Integer as its source. 3. The Java stream filter(...

Java Stream API - How to convert List of objects to another List of objects using Java streams?

Image
In this section, we will show you how to convert a List of objects to another List of objects in Java using the Java streams map(). The ‘map’ method maps each element to its corresponding result. Java Stream API   The Java Stream API provides a functional programming approach over the object oriented capabilities of Java. It is used for processing collections of objects. The Stream in Java can be defined as a sequence of elements from a source List, Set or Array. Most of the stream operations return a Stream. This avails engender a chain of stream operations(stream pipe-lining). The streams withal support the aggregate or terminal operations on the elements. for example, finding the sum or maximum element or finding the average etc...Stream operations can either be executed sequentially or parallel. when performed parallelly, it is called a parallel stream.   Stream map() Method   The Java 8 Stream map() is an intermediate operation. It converts Stream<obj1> to Str...

Top 5 Java ORM tools - 2024

Image
  The term ORM refers to object-relational mapping, which uses objects to adapt programming languages to database systems while allowing them to function with SQL and object-oriented programming ideas. Any kind of database management system that can accomplish object mapping to the table in the virtual system is suitable for the implementation of ORM. Java has a wide variety of ORM tools, some of which are mentioned below: 1. Hibernate Hibernate is a lightweight, open-source, non-invasive Java ORM (Object-Relational Mapping) framework that allows developers to create objects that function independently of database software and create persistence logic in any Java or JavaEE application. It offers an abstraction layer, so developers don't have to bother about implementations; Hibernate handles these tasks internally, such as connecting to databases and creating queries to carry out CRUD operations, among other things. Persistence logic development is done with it. Persistence logic r...

Java - Blowfish Encryption and decryption Example

Image
Blowfish is an encryption method developed by Bruce Schneier in 1993 as an alternative to the DES encryption method. It is significantly faster than DES and provides good encryption speed, although no effective cryptanalysis technique has been found to date. It is one of the first secure block ciphers that is not protected by any patents and is therefore freely available for anyone to use. This is a symmetric block cipher algorithm. Block size: 64 bits Key size: variable size from 32 to 448 bits number of subsections: 18 [P-array] number of rounds: 16 number of substitution blocks: 4 [each with 512 records of 32 bits each] develop  Example 1: Encryption and decryption using Blowfish import java.io.UnsupportedEncodingException; import java.nio.charset.Charset; import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException; import java.util.Base64; import javax.crypto.BadPaddingException; import javax.crypto.Cipher; import javax.crypto.IllegalBlockSiz...
