志不强者智不达，言不信者行不果。这篇文章主要讲述k8s-监控组件:heaper部署相关的知识，希望能为你提供帮助。

【k8s-监控组件:heaper部署】heapster：数据采集
influxdb：数据存储
grafana：web展示
1.准备镜像及配置文件

mkdir /etc/ansible/manifests/dns/kube-dns/heapster
cd /etc/ansible/manifests/dns/kube-dns/heapster

2.导入镜像及上传到本地harbor仓库

docker load -i heapster-amd64_v1.5.1.tar & & \\
docker load -i heapster-grafana-amd64-v4.4.3.tar & & \\
docker load -i heapster-influxdb-amd64_v1.3.3.tar

docker tag 4129aa919411harbor.gesila.com/k8s/heapster-amd64:v1.5.1 & & \\
docker tag 8cb3de219af7harbor.gesila.com/k8s/heapster-grafana-amd64:v4.4.3 & & \\
docker tag 1315f002663charbor.gesila.com/k8s/heapster-influxdb-amd64:v1.3.3

docker push harbor.gesila.com/k8s/heapster-amd64:v1.5.1 & & \\
docker push harbor.gesila.com/k8s/heapster-grafana-amd64:v4.4.3 & & \\
docker push harbor.gesila.com/k8s/heapster-influxdb-amd64:v1.3.3

3.修改配置文件镜像源

vim grafana.yaml
-name: grafana
images: harbor.gesila.com/k8s/heapster-grafana-amd64:v4.4.3

vim heapster.yaml
-name: heapster
images: harbor.gesila.com/k8s/heapster-amd64:v1.5.1

vim influxdb.yaml
-name: influxdb
images: harbor.gesila.com/k8s/heapster-influxdb-amd64:v1.3.3

4.构建

root@k8s-master:/etc/ansible/manifests/dns/kube-dns/heapster# kubectl apply -f .
deployment.extensions/monitoring-grafana created
service/monitoring-grafana created
serviceaccount/heapster created
clusterrolebinding.rbac.authorization.k8s.io/heapster created
deployment.extensions/heapster created
service/heapster created
deployment.extensions/monitoring-influxdb created
service/monitoring-influxdb created

5.查看

root@k8s-master:/etc/ansible/manifests/dns/kube-dns/heapster# kubectl get pods -n kube-system
