[Bug] SIGSEGV when creating a cluster with custom AMI #7882
Description
What were you trying to accomplish?
Create a cluster with custom AMI
How to reproduce it?
Created an yaml like this
$ cat test-cluster.yaml
# An example of ClusterConfig object with ipFamily set to ipv6:
---
apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
name: senthilx-july9-cluster-6
region: us-west-1
version: "1.29"
kubernetesNetworkConfig:
ipFamily: IPv6
addons:
- name: vpc-cni
version: latest
- name: coredns
version: latest
- name: kube-proxy
version: latest
iam:
withOIDC: true
managedNodeGroups:
- amiFamily: AmazonLinux2023
ami: ami-06780da4f9e123591
name: mng-1
And tried to create a cluster
./eksctl create cluster -f test-cluster.yaml
And cluster create crashes in this step.
