Kubernetes 部署 Weave-Scope

Kubernetes 部署 Weave-Scope

1、下载镜像

docker pull docker.io/weaveworks/scope:1.6.7

2、获取weave-scope的yaml文件

curl https://cloud.weave.works/k8s/scope.yaml?k8s-version=1.6.7 -sL -o scope.yaml

参考自：https://www.weave.works/docs/scope/latest/installing/

* 完整yaml 文件如下：*

4、部署Weave-Scope

kubectl apply --namespace kube-system -f scope.yaml
