EKS Fargate and Observability setup

In this chapter, we will perform the following tasks in your existing EKS cluster eksworkshop-eksctl.

  • Create Fargate Profile
  • Enable OIDC Provider
  • Create Namespace for Application Deployment
  • Create IRSA (IAM Role for Service Account) for Application Namespace prodcatalog-ns
  • Enable Observability for Logs and Metrics

PreRequisite

  • We assume that we have an existing EKS Cluster eksworkshop-eksctl created from EKS Workshop.

  • We also assume that we have increased the disk size on your Cloud9 instance as we need to build docker images for our application.

  • We will be using AWS Console to navigate and explore resources in Amazon EKS, AWS App Mesh, Amazon Cloudwatch, AWS X-Ray in this workshop. So ensure that you have completed Console Credentials to get full access to your existing EKS Cluster eksworkshop-eksctl in the EKS console.

  • Check if AWS_REGION and ACCOUNT_ID are set correctly

    test -n "$AWS_REGION" && echo AWS_REGION is "$AWS_REGION" || echo AWS_REGION is not set
test -n "$ACCOUNT_ID" && echo ACCOUNT_ID is "$ACCOUNT_ID" || echo ACCOUNT_ID is not set

    If not, export the ACCOUNT_ID and AWS_REGION to ENV 

    
export ACCOUNT_ID=<your_account_id>
export AWS_REGION=<your_aws_region>

  • Clone the repository to your local workspace with this command:

cd ~/environment
git clone https://github.com/aws-containers/eks-app-mesh-polyglot-demo.git
cd eks-app-mesh-polyglot-demo

Now lets, create the Fargate Profile in our EKS cluster to deploy one prodcatalog service in our Product Catalog Application.
