Kubernetes dashboard集成heapster
图形化展示度量指标的实现需要集成k8s的另外一个Addons组件： Heapster 。Heapster原生支持K8s(v1.0.6及以后版本)和 CoreOS ，并且支持多种存储后端，比如： InfluxDB 、 ElasticSearch 、 Kafka 。
下载源包和images文件
下载地址https://github.com/kubernetes/heapster/archive/v1.2.0.zip,将包copy到kubernetes master节点上去.
打开deploy/kube-config/influxdb目录看到5个部署文件

参看这几个 yaml文件,预先把需要pull的image在nodes节点上准备好
docker pull kubernetes/heapster:canary
docker pull kubernetes/heapster_influxdb:v0.5
docker pull gcr.io/google_containers/heapster_grafana:v2.6.0-2
运行创建(master)
然后在master节点上运行
kubectl create -f deploy/kube-config/influxdb/ 通过kube get pods -n kube-system发现heapster-zm85m没有运行起来,基于下面命令查看日志

kubectl logs -f pods/heapster-zm85m -n kube-system 发现错误

编辑heapster-control.yaml文件,把其中source这行替换成本机的api server ip并添加?inClusterConfig=false
删除之前创建的pod重新create一遍.
spec: containers:
- name: heapster
image: kubernetes/heapster:canary
imagePullPolicy: Always
command:
- /heapster
- --source=kubernetes:http://<api server ip>:<port>?inClusterConfig=false
- --sink=influxdb:http://monitoring-influxdb:8086
最后的yaml文件:
# cat heapster-controller.yaml
apiVersion: v1
kind: ReplicationController
metadata:
labels:
k8s
-app: heapster name: heapster
version: v6
name: heapster
namespace: kube-system
spec:
replicas:
1 selector:
k8s
-app: heapster version: v6
template:
metadata:
labels:
k8s
-app: heapster version: v6
spec:
containers:
- name: heapster image: kubernetes
/heapster:canary command:
- /heapster- --source=kubernetes:http://10.182.169.33:8080?inClusterConfig=false - --sink=influxdb:http://monitoring-influxdb:8086
# kubectl delete-f deploy/kube-config/influxdb/
# kubectl create -f deploy/kube-config/influxdb/
再次打开kubernetes dashboard,就可以看到获取的监控数据啦
