安装weave scope

kubectl apply -f init.yaml
kubectl get pods -n weave -o wide -w

修改为NodePort

kubectl patch svc $(kubectl get svc -n weave |grep weave-scope-app |awk '{print $1}') -p '{"spec":{"type": "NodePort"}}' -n weave
kubectl get svc -n weave |grep weave-scope-app

感觉看起来还行可以帮助理解服务之间的调用

点击pod 并选择边上container里的pod在点击Attach

然后就嘎住了。哈哈哈不能进入到pod里

describe和log 功能都正常
