安装 AWS Load Balancer Controller 附加组件

news 2025/7/7 9:06:04

1 创建一个 IAM policy

#curl -O https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/v2.4.4/docs/install/iam_policy.json#aws iam create-policy \--policy-name AWSLoadBalancerControllerIAMPolicy \--policy-document file://iam_policy.json

2 创建一个 IAM 角色

my-cluster ：需要更改为真实的EKS集群名称

111122223333：代表AWS ID帐号，也需要更改111122223333

# eksctl utils associate-iam-oidc-provider --region=ap-southeast-1 --cluster=my-cluster# eksctl create iamserviceaccount \--cluster=my-cluster \--namespace=kube-system \--name=aws-load-balancer-controller \--role-name AmazonEKSLoadBalancerControllerRole \--attach-policy-arn=arn:aws:iam::111122223333:policy/AWSLoadBalancerControllerIAMPolicy \--approve

3 使用Helm v3安装AWS Load Balancer Controller

1）添加 eks-charts 存储库

#helm repo add eks https://aws.github.io/eks-charts

2）更新您的本地存储库，以确保您拥有最新的图表

#helm repo update
#helm install aws-load-balancer-controller eks/aws-load-balancer-controller \-n kube-system \--set clusterName=my-cluster \--set serviceAccount.create=false \--set serviceAccount.name=aws-load-balancer-controller

4 验证控制器是否已安装

#kubectl get deployment -n kube-system aws-load-balancer-controller

输出示例如下：

NAME                           READY   UP-TO-DATE   AVAILABLE   AGE
aws-load-balancer-controller   2/2     2            2           84s

5 常见问题解决

删除命令：helm delete -n kube-system aws-load-balancer-controller

报错：

2023-05-24 03:22:03 [ℹ] 1 existing iamserviceaccount(s) (kube-system/aws-load-balancer-controller) will be excluded
2023-05-24 03:22:03 [ℹ] 1 iamserviceaccount (kube-system/aws-load-balancer-controller) was excluded (based on the include/exclude rules)
2023-05-24 03:22:03 [!] serviceaccounts that exist in Kubernetes will be excluded, use --override-existing-serviceaccounts to override
2023-05-24 03:22:03 [ℹ] no tasks
解决办法：

修改以下名称保证唯一性，不建议共用。（可能帐号下有重复的名称导致）

--name=aws-load-balancer-controller

--role-name AmazonEKSLoadBalancerControllerRole
