安装 AWS Load Balancer Controller 附加组件
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-charts2）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
