[Bug] EKSCTL 0.189.0 panic: runtime error: invalid memory address or nil pointer dereference

Open ttirtawi opened this issue 1 year ago • 2 comments

What were you trying to accomplish?

Using the standard YAML file, I always see the following warning about IRSA deprecation:

2024-08-28 13:50:25 [!]  recommended policies were found for "vpc-cni" addon, but since OIDC is disabled on the cluster, eksctl cannot configure the requested permissions; the recommended way to provide IAM permissions for "vpc-cni" addon is via pod identity associations; after addon creation is completed, add all recommended policies to the config file, under `addon.PodIdentityAssociations`, and run `eksctl update addon`

2024-08-28 13:56:59 [!]  IRSA has been deprecated; the recommended way to provide IAM permissions for "aws-efs-csi-driver" addon is via pod identity associations; after addon creation is completed, run `eksctl utils migrate-to-pod-identity`


2024-08-28 13:58:31 [!]  IRSA has been deprecated; the recommended way to provide IAM permissions for "aws-ebs-csi-driver" addon is via pod identity associations; after addon creation is completed, run `eksctl utils migrate-to-pod-identity`

So I'm trying to create a new cluster with Addon and pod identity agent simultaneously so that I don't need to do migrate-to-pod-identity after cluster has been created, but the process crash due to SIGSEGV when creating vpc-cni addon.

What happened?

This is the error I got

@ttirtawi, we have identified the issue and will work on a fix soon. In the meantime, I'd recommend working around this by removing iam.withOIDC as you do not seem to be using IRSA.

I encountered the same crash and can confirm that this workaround works. :+1:

However, I think there might be a related documentation issue on this page. The following sentence led me to assume that IRSA/OIDC was still required, so maybe it could be clarified:

Pod Identity Association leverages IRSA, however, it makes it configurable directly through EKS API, eliminating the need for using IAM API altogether.
