Setting up WeaveScope for visualizing Kubernetes Pods, Services, Containers & Hosts

Pre-requisite

• Docker for Mac
• GKE Cluster
• The docker context shows you GKE Cluster

kubectl create clusterrolebinding "cluster-admin-$(whoami)" --clusterrole=cluster-admin --user="$(gcloud config get-value core/account)"

Installing WeaveScope

kubectl apply -f "https://cloud.weave.works/k8s/scope.yaml?k8s-version=$(kubectl version | base64 | tr -d '\n')"

This downloads a recent Scope image from Dockerhub and launches a probe onto every node as well as a single Scope app. Once launched, Scope doesn’t require any other configuration.

Allowable parameters for the launcher URL:

v - Weave Scope version or tag, e.g. latest current release is the default
k8s-service-type - Kubernetes service type (for running Scope in Standalone mode), can be either LoadBalancer or NodePort, by default this is unspecified (only internal access)

Open Scope in Your Browser

kubectl port-forward -n weave "$(kubectl get -n weave pod --selector=weave-scope-component=app -o jsonpath='{.items..metadata.name}')" 4040

Now get ready to access via http://localhost:4040.

Note:

If you're using Docker Desktop for Mac, follow the below steps:

kubectl apply -f https://github.com/weaveworks/scope/releases/download/v1.13.2/k8s-scope.yaml
kubectl port-forward -n weave "$(kubectl get -n weave pod --selector=weave-scope-component=app -o jsonpath='{.items..metadata.name}')" 4040

The URL is: http://localhost:4040.
