二、安装Metrics Server

使用Helm安装

  1. helm repo add bitnami https://charts.bitnami.com/bitnami
  2. helm install nginx bitnami/nginx -n test

部署完成，控制台打印：

  1. NAME: nginx
  2. LAST DEPLOYED: Sun Nov  1 21:28:17 2020
  3. NAMESPACE: test
  4. STATUS: deployed
  5. REVISION: 1
  6. TEST SUITE: None
  7. NOTES:
  8. ** Please be patient while the chart is being deployed **
  10. NGINX can be accessed through the following DNS name from within your cluster:
  12.     nginx.test.svc.cluster.local (port 80)
  14. To access NGINX from outside the cluster, follow the steps below:
  16. 1. Get the NGINX URL by running these commands:
  18.   NOTE: It may take a few minutes for the LoadBalancer IP to be available.
  19.         Watch the status with: 'kubectl get svc --namespace test -w nginx'
  21.     export SERVICE_PORT=$(kubectl get --namespace test -o jsonpath="{.spec.ports[0].port}" services nginx)
  22.     export SERVICE_IP=$(kubectl get svc --namespace test nginx -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
  23.     echo "http://${SERVICE_IP}:${SERVICE_PORT}"

使用YAML安装
