配置和安装 Heapster

到 heapster release 页面 下载最新版本的 heapster

$ wget https://github.com/kubernetes/heapster/archive/v1.3.0.zip
$ unzip v1.3.0.zip
$ mv v1.3.0.zip heapster-1.3.0
$

文件目录： heapster-1.3.0/deploy/kube-config/influxdb

$ cd heapster-1.3.0/deploy/kube-config/influxdb
$ ls *.yaml
grafana-deployment.yaml  grafana-service.yaml  heapster-deployment.yaml  heapster-service.yaml  influxdb-deployment.yaml  influxdb-service.yaml

已经修改好的 yaml 文件见：heapster

配置 grafana-deployment

$ diff grafana-deployment.yaml.orig grafana-deployment.yaml
16c16
<         image: gcr.io/google_containers/heapster-grafana-amd64:v4.0.2
---
>         image: lvanneo/heapster-grafana-amd64:v4.0.2
40,41c40,41
<           # value: /api/v1/proxy/namespaces/kube-system/services/monitoring-grafana/
<           value: /
---
>           value: /api/v1/proxy/namespaces/kube-system/services/monitoring-grafana/
>           #value: /
  • 如果后续使用 kube-apiserver 或者 kubectl proxy 访问 grafana dashboard，则必须将 GF_SERVER_ROOT_URL 设置为 /api/v1/proxy/namespaces/kube-system/services/monitoring-grafana/，否则后续访问grafana时访问时提示找不到http://10.64.3.7:8086/api/v1/proxy/namespaces/kube-system/services/monitoring-grafana/api/dashboards/home 页面；

配置 heapster-deployment

$ diff heapster-deployment.yaml.orig heapster-deployment.yaml
16c16
<         image: gcr.io/google_containers/heapster-amd64:v1.3.0-beta.1
---
>         image: lvanneo/heapster-amd64:v1.3.0-beta.1

配置 influxdb-deployment

$ diff influxdb-deployment.yaml.orig influxdb-deployment.yaml
16c16
<         image: gcr.io/google_containers/heapster-influxdb-amd64:v1.1.1
---
>         image: lvanneo/heapster-influxdb-amd64:v1.1.1

执行所有定义文件

$ pwd
/root/heapster-1.3.0/deploy/kube-config/influxdb
$ ls *.yaml
grafana-deployment.yaml  grafana-service.yaml  heapster-deployment.yaml  heapster-service.yaml  influxdb-deployment.yaml  influxdb-service.yaml
$ kubectl create -f  .
deployment "monitoring-grafana" created
service "monitoring-grafana" created
deployment "heapster" created
service "heapster" created
deployment "monitoring-influxdb" created
service "monitoring-influxdb" created

检查执行结果

检查 Deployment

$ kubectl get deployments -n kube-system | grep -E 'heapster|monitoring'
heapster               1         1         1            1           1m
monitoring-grafana     1         1         1            1           1m
monitoring-influxdb    1         1         1            1           1m

检查 Pods

$ kubectl get pods -n kube-system | grep -E 'heapster|monitoring'
heapster-3273315324-tmxbg               1/1       Running   0          11m
monitoring-grafana-2255110352-94lpn     1/1       Running   0          11m
monitoring-influxdb-884893134-3vb6n     1/1       Running   0          11m

检查 kubernets dashboard 界面，看是显示各 Nodes、Pods 的 CPU、内存、负载等利用率曲线图；

dashboard-heapster

访问 grafana

  1. 通过 kube-apiserver 访问：

    获取 monitoring-grafana 服务 URL

    $ kubectl cluster-info
Kubernetes master is running at http://10.64.3.7:8080
Heapster is running at http://10.64.3.7:8080/api/v1/proxy/namespaces/kube-system/services/heapster
KubeDNS is running at http://10.64.3.7:8080/api/v1/proxy/namespaces/kube-system/services/kube-dns
kubernetes-dashboard is running at http://10.64.3.7:8080/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard
monitoring-grafana is running at http://10.64.3.7:8080/api/v1/proxy/namespaces/kube-system/services/monitoring-grafana
monitoring-influxdb is running at http://10.64.3.7:8080/api/v1/proxy/namespaces/kube-system/services/monitoring-influxdb
$

    浏览器访问 URL： http://10.64.3.7:8080/api/v1/proxy/namespaces/kube-system/services/monitoring-grafana

  2. 通过 kubectl proxy 访问：

    创建代理

    $ kubectl proxy --address='10.64.3.7' --port=8086 --accept-hosts='^*$'
Starting to serve on 10.64.3.7:8086

    浏览器访问 URL：http://10.64.3.7:8086/api/v1/proxy/namespaces/kube-system/services/monitoring-grafana
