Setup AWS APP Mesh on EKS

To install AWS App Mesh in your Amazon EKS cluster, you can follow these step-by-step instructions:

1. Connect with AWS Account:
   • Use the AWS CLI to configure your AWS access key, secret access key, and region:

     aws configure
     

2. Create an EKS Cluster:
   • If you don’t have an existing EKS cluster, create one using eksctl create cluster[1].
3. Connect with EKS Cluster:
   • Update the Kubeconfig to connect with the EKS cluster:

     aws eks update-kubeconfig --name mesh-test-cluster
     

4. Add eks-charts Repository to Helm:
   • Install the App Mesh Kubernetes custom resource definitions (CRD) using kubectl apply:

     kubectl apply -k "https://github.com/aws/eks-charts/stable/appmesh-controller/crds?ref=master"
     

5. Create appmesh-system Namespace:
   • Create a namespace for the App Mesh controller:

     kubectl create ns appmesh-system
     

6. Create an OpenID Connect (OIDC) Identity Provider:
   • Create an OIDC identity provider for your cluster using eksctl utils associate-iam-oidc-provider[1].
7. Create an IAM Role:
   • Create an IAM role, attach the AWSAppMeshFullAccess and AWSCloudMapFullAccess policies, and bind it to the appmesh-controller Kubernetes service account:

     eksctl create iamserviceaccount \
       --cluster mesh-test-cluster \
       --namespace appmesh-system \
       --name appmesh-controller \
       --attach-policy-arn arn:aws:iam::aws:policy/AWSCloudMapFullAccess,arn:aws:iam::aws:policy/AWSAppMeshFullAccess \
       --override-existing-serviceaccounts \
       --approve
     

8. Deploy the App Mesh Controller:
   • Deploy the App Mesh controller using Helm:

     helm upgrade -i appmesh-controller eks/appmesh-controller \
       --namespace appmesh-system \
       --set region=ap-south-1 \
       --set serviceAccount.create=false \
       --set serviceAccount.name=appmesh-controller
     

9. Verify Controller Pod Running:
   • Verify that the Controller pod is running:

     kubectl get pods -n appmesh-system
     

10. Create Mesh:
    • Create a mesh using the App Mesh controller. You can create a mesh from AWS CLI, AWS Console, or Kubernetes native YAML[1].

By following these steps, you can successfully install AWS App Mesh in your Amazon EKS cluster.
