使用weavescope监控集群

#查看kuberntes 版本
kubectl version

#下载对应版本yaml文件
curl https://cloud.weave.works/k8s/scope.yaml?k8s-version=1.11.1 -sL -o scope.yaml

#查看scope.yaml文件里所使用镜像的版本，并下载
docker pull docker.io/weaveworks/scope:1.10.2

#执行
kubectl apply --namespace weave -f scope.yaml

#编辑修改svc中type: ClusterIP 为 type: NodePort
#修改为NodePort与外界交互
kubectl edit service weave-scope-app -n weave

#查看修改后的pod情况

[root@k8s-master weavescope]#kubectl get pods -n weave -o wide
