[AWS] EKS - Load Balancer Controller 설치 및 ALB 생성

EKS Cluster에 Load Balancer Controller 설치한 후에 ALB 생성해보도록 하겠습니다.

 

• EKS OIDC Provider

CLUSTER_NAME="ydy-eks"
eksctl utils associate-iam-oidc-provider --cluster ${CLUSTER_NAME} --approve

• IAM Policy / Role 생성

curl -O https://raw.githubusercontent.com/kubernetes-sigs/aws-load-balancer-controller/v2.4.7/docs/install/iam_policy.json

aws iam create-policy \
    --policy-name AWSLoadBalancerControllerIAMPolicy-eks-ydy \
    --policy-document file://iam_policy.json
    
POLICY_ARN=$(aws iam list-policies --query 'Policies[?PolicyName==`AWSLoadBalancerControllerIAMPolicy-eks-ydy`].Arn' --output text)
ROLE_NAME="AmazonEKSLoadBalancerControllerRole-eks-ydy"

eksctl create iamserviceaccount \
  --cluster ${CLUSTER_NAME} \
  --namespace=kube-system \
  --name=aws-load-balancer-controller \
  --role-name ${ROLE_NAME} \
  --attach-policy-arn=${POLICY_ARN} \
  --approve

• helm 설치

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh

• helm chart 추가

helm chart 추가
helm repo add eks https://aws.github.io/eks-charts
helm repo update

helm aws-load-balancer-controller 설치
helm upgrade --install aws-load-balancer-controller eks/aws-load-balancer-controller \
-n kube-system \
--set clusterName=${CLUSTER_NAME} \
--set serviceAccount.create=false \
--set serviceAccount.name=aws-load-balancer-controller \
--set region=ap-northeast-2 \
--set vpcId=my-vpc-ID

helm aws-load-balancer-controller 삭제 명령어
helm delete aws-load-balancer-controller -n kube-system
