Kubernetes: Weave Scope with Minikube

Weave Scope is a visualization and monitoring tool for Docker and Kubernetes. It provides a top down view into your app as well as your entire infrastructure, and allows you to diagnose any problems with your distributed containerized app, in real time, as it is being deployed to a cloud provider.

kubectl edit svc weave-scope-app -n weave
 service/weave-scope-app edited

Deployment

Create an example deployment.

kubectl run --image=weaveworks/hello-world hello

View Service

You should see that a random NodePort has been assigned for external access.

kubectl get svc -n weave
 NAME              TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
 weave-scope-app   NodePort   10.103.242.70           80:31871/TCP   5m46s
