在LocalStack EKS中操作Kubernetes集群时出现EOF错误，端口是否为原因？

操作流程与问题现象 #

1. 创建EKS集群：

awslocal eks create-cluster \
  --name cluster1 \
  --role-arn "arn:aws:iam::000000000000:role/eks-role" \
  --resources-vpc-config "{}"

2. 确认集群状态为ACTIVE，返回结果中集群端点为https://localhost.localstack.cloud:4511：

awslocal eks describe-cluster --name cluster1
{
    "cluster": {
        "name": "cluster1",
        "arn": "arn:aws:eks:ap-northeast-1:000000000000:cluster/cluster1",
        "createdAt": "2024-05-22T13:52:00.327000+09:00",
        "version": "1.22",
        "endpoint": "https://localhost.localstack.cloud:4511",
        "roleArn": "arn:aws:iam::000000000000:role/eks-role",
        "resourcesVpcConfig": {
            "securityGroupIds": [],
            "endpointPublicAccess": true,
            "endpointPrivateAccess": false,
            "publicAccessCidrs": [
                "0.0.0.0/0"
            ]
        },
        "identity": {
            "oidc": {
                "issuer": "https://localhost.localstack.cloud/eks-oidc"
            }
        },
        "status": "ACTIVE",
....
}

3. 配置Kubernetes上下文：

awslocal eks update-kubeconfig --name cluster1 && \
    kubectl config use-context arn:aws:eks:ap-northeast-1:000000000000:cluster/cluster1

4. 执行kubectl命令时触发错误：

kubectl get po
I0522 14:04:44.688006   27587 versioner.go:58] Get "https://localhost.localstack.cloud:4511/version?timeout=5s": EOF
E0522 14:04:55.119358   27587 memcache.go:265] couldn't get current server API group list: Get "https://localhost.localstack.cloud:4511/api?timeout=32s": EOF

疑问 #

注意到EKS集群的端点使用4511端口，但LocalStack的默认端口是4566，请问端口不一致是否是导致上述kubectl连接错误的原因？
