If rok-deploy is not already running, start it with:

root@rok-tools:~# rok-deploy --run-from serving-eks-alb-alb
../../../../_images/eks-alb-alb1.png

Proceed to the Summary section.

Option 2: Deploy AWS Load Balancer Controller Manually

If you want to deploy AWS Load Balancer Controller manually, follow the instructions below.

Procedure

  1. Go to your GitOps repository, inside your rok-tools management environment:

    root@rok-tools:~# cd ~/ops/deployments
  2. Restore the required context from previous sections:

    root@rok-tools:~/ops/deployments# source <(cat deploy/env.{envvars-aws,\ > aws-vpc,eks-cluster,eks-alb-iam-alb})
    root@rok-tools:~/ops/deployments# export AWS_DEFAULT_REGION AWS_VPC_ID \ > EKS_CLUSTER EKS_ALB_IAM_ALB_ROLE
  3. Render the AWS Load Balancer Controller deployment patch template with the variables you have specified:

    root@rok-tools:~/ops/deployments# j2 \ > rok/aws-load-balancer-controller/overlays/deploy/patches/deploy.yaml.j2 \ > -o rok/aws-load-balancer-controller/overlays/deploy/patches/deploy.yaml
  4. Obtain the ARN of the IAM role for AWS Load Balancer Controller:

    root@rok-tools:~/ops/deployments# export ROLE_ARN=$(aws iam get-role \ > --role-name ${EKS_ALB_IAM_ALB_ROLE?} \ > --query Role.Arn \ > --output text)
  5. Render the AWS Load Balancer Controller service account patch template with the variables you have specified:

    root@rok-tools:~/ops/deployments# j2 \ > rok/aws-load-balancer-controller/overlays/deploy/patches/sa.yaml.j2 \ > -o rok/aws-load-balancer-controller/overlays/deploy/patches/sa.yaml
  6. Commit your changes:

    root@rok-tools:~/ops/deployments# git commit -am "Deploy AWS Load Balancer Controller"
  7. Deploy AWS Load Balancer Controller:

    root@rok-tools:~/ops/deployments# rok-deploy --apply rok/aws-load-balancer-controller/overlays/deploy

Verify

  1. Verify that the AWS Load Balancer Controller deployment is up-and-running. Verify field READY is 1/1:

    root@rok-tools:~# kubectl get -n kube-system deploy/aws-load-balancer-controller NAME READY UP-TO-DATE AVAILABLE AGE aws-load-balancer-controller 1/1 1 1 1m

Summary

You have successfully deployed AWS Load Balancer Controller.

What’s Next

The next step is to configure the ALB type and subnets.
