啟用網站

確定要啟用的網站所關聯的網路負載平衡器 (NLB) 的 ARN

命令

NAMESPACE= (1)
REGION= (2)
HOSTNAME=$(kubectl -n $NAMESPACE get svc accelerator-loadbalancer --template="{{range .status.loadBalancer.ingress}}{{.hostname}}{{end}}")
aws elbv2 describe-load-balancers \
  --query "LoadBalancers[?DNSName=='${HOSTNAME}'].LoadBalancerArn" \
  --region ${REGION} \
  --output text

1	包含 Keycloak 部署的 Kubernetes 命名空間
2	託管 Kubernetes 叢集的 AWS 區域

輸出

arn:aws:elasticloadbalancing:eu-west-1:606671647913:loadbalancer/net/a49e56e51e16843b9a3bc686327c907b/9b786f80ed4eba3d

更新 Accelerator EndpointGroup 以包含兩個網站

列出 Global Accelerator 的 EndpointGroup 中的目前端點

命令

ACCELERATOR_NAME= (1)
ACCELERATOR_ARN=$(aws globalaccelerator list-accelerators \
  --query "Accelerators[?Name=='${ACCELERATOR_NAME}'].AcceleratorArn" \
  --region us-west-2 \ (2)
  --output text
)
LISTENER_ARN=$(aws globalaccelerator list-listeners \
  --accelerator-arn ${ACCELERATOR_ARN} \
  --query "Listeners[*].ListenerArn" \
  --region us-west-2 \
  --output text
)
aws globalaccelerator list-endpoint-groups \
  --listener-arn ${LISTENER_ARN} \
  --region us-west-2

1	要更新的 Accelerator 名稱
2	查詢 AWS Global Accelerator 時，區域必須始終設定為 us-west-2

輸出
