EKS AWS Load Balancer Controller - ingress created but the ALB is not

Question

I installed AWS Load Balancer Controller through Helm.
The ingress is created but the ALB is not and I am getting an error.

I followed the guide below.
-> https://docs.aws.amazon.com/ko_kr/eks/latest/userguide/aws-load-balancer-controller.html

* Deployment / Service - logs ERROR
{"level":"error","ts":1674024616.2905765,"logger":"controller.ingress","msg":"Reconciler error","name":...,"namespace":...,"error":"UnauthorizedOperation: You are not authorized to perform this operation.
	status code: 403}
* ingress ERROR
Warning  FailedBuildModel  19s  ingress  Failed build model due to UnauthorizedOperation: You are not authorized to perform this operation.
           status code: 403

Answer

At the first glance, this seems like permission error. Have You checked Your IAM policies and IAM roles if they are set up correctly?

Is Your cluster in US-East or US-West region or other region (step 1.a. and 1.b. of provided link)?

Is the service account created correctly (step 2. of the provided link)?

Can You provide the exact helm command that You've run - without sensitive information?

Answer

The error message "UnauthorizedOperation: You are not authorized to perform this operation. status code: 403" typically indicates that the AWS Load Balancer Controller does not have the necessary permissions to create or modify resources in your AWS account.

Here are a few things you can check to troubleshoot the issue:

Verify that the AWS credentials you are using to authenticate the Load Balancer Controller have the necessary permissions to create and modify resources in your AWS account.

Ensure that the IAM role associated with the Load Balancer Controller has the necessary permissions to create and modify resources in your AWS account.

Make sure that the Load Balancer Controller has the necessary permissions to access the resources specified in the Ingress resource.

If you are using an IAM Role for Service Accounts (IRSA) for authentication, check if the role is correctly associated with the LoadBalancer controller

Verify that you are running the Load Balancer Controller in the same AWS account and region as the resources it is trying to access.

Check the AWS Load Balancer Controller log for more information about the error.

If you are still having issues after going through these steps, you might want to refer to the AWS Load Balancer Controller documentation or AWS Support for further assistance.

I Solved!!!!!!

https://docs.aws.amazon.com/ko_kr/eks/latest/userguide/aws-load-balancer-controller.html => v2.4.4

I changed v2.2.0 (curl -o iam_policy.json https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/v2.2.0/docs/install/iam_policy.json)

It works!!!!!!

But I can't understand why the official website version is not available...

Answer

Everything You provided seems correct.

If the role created - eksctl-XXXXXX-addon-iamserviceacc-Role1-XXXXXX - has AWSLoadBalancerControllerIAMPolicy attached,, You can check this by running:
```
aws iam list-attached-role-policies --role-name eksctl-XXXXXX-addon-iamserviceacc-Role1-XXXXXX
```

If it is attached and I believe it is, try steps mentioned in comment above by Ahmad Ul Islam.
