This guide provides step-by-step instructions for productionalizing this FinBERT Flask App on AWS EKS using eksctl to setup the kubernetes cluster on EKS and setting up a CI/CD pipeline with GitHub Actions.

• AWS account with appropriate permissions.
  • Review this document for required permissions on EKS: https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonelastickubernetesservice.html
• aws CLI installed and configured.
  • Getting started with aws CLI: https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html
  • Quick configuration guide: https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html#cli-configure-quickstart-config
• eksctl and kubectl tools installed.
  • Getting started with eksctl: https://docs.aws.amazon.com/eks/latest/userguide/getting-started-eksctl.html
  • Getting started with kubectl: https://docs.aws.amazon.com/eks/latest/userguide/install-kubectl.html
• GitHub account and repository for the app.

• Install and configure the AWS CLI:

  aws configure

• Enter your AWS Access Key ID, Secret Access Key, region, and output format.

• Create a new ECR repository to store your Docker images:

  aws ecr create-repository --repository-name finbert-flask-app

• Create an IAM user with programmatic access and necessary permissions for ECR and EKS.
• Note down the Access Key ID and Secret Access Key.

• To create your EKS cluster, use the following eksctl commands (as specified in your provided files):

  eksctl create cluster --name finbert-cluster --region us-east-1 --node-type t3.small --node-ami-family Ubuntu2004 --nodes-min 2 --nodes-max 3 # --dry-run # uncomment to do a dry run to validate the cluster config

• For additional configuration and options, refer to the eksctl documentation.

• To delete specific deployments or services in your cluster:

  kubectl delete deployment <deployment-name>
  kubectl delete service <service-name>

• To delete your EKS cluster:

  eksctl delete cluster --name finbert-cluster

• Go to your GitHub repository > Settings > Secrets.
• Add the following secrets:
  • AWS_ACCESS_KEY_ID: The Access Key ID of the IAM user.
  • AWS_SECRET_ACCESS_KEY: The Secret Access Key of the IAM user.
• Add the following variables:
  • AWS_REGION: Your AWS region.
  • ECR_REPOSITORY: Name of the ECR repository.
  • EKS_CLUSTER_NAME: Name of the EKS cluster.

• Create a .github/workflows directory in your repository.
• Add a workflow file (e.g., ci-cd.yml).
• Define steps for building, pushing the Docker image, and deploying to EKS.

• Push changes to your repository.
• GitHub Actions will build the Docker image and deploy it to EKS.

• eksctl creates a CloudFormation stack for the EKS cluster, which can be viewed in the CloudFormation console or addtionally one could use cf2tf to convert the CloudFormation stack to Terraform code.
