Scope comes with built-in Kubernetes support. We recommend to run Scope natively
in your Kubernetes cluster using
[this resource definitions](https://github.com/TheNewNormal/kube-charts/tree/master/weavescope/manifests)
which are easily deployable with [Helm](https://helm.sh/).

1. If you are running a Kubernetes version lower than 1.1, make sure your
cluster allows running pods in privileged mode (required by the Scope
probes). To allow privileged pods, your API Server and all your Kubelets must
be provided with flag `--allow_privileged` at launch time.

6. Install Scope in your cluster by using kubectl directly. Unfortunately `helm
install` cannot be used because the Scope App is optional (only needed in
standalone installations) and
[a specific deployment order is required](https://github.com/TheNewNormal/kube-charts/blob/915fcacb2a14f8b6a42c44ca5e2d217e21945137/weavescope/manifests/scope-probe-ds.yaml#L40-L42)):
5. Install Scope in your cluster (order is important):
```
kubectl create -f $HOME/.helm/workspace/charts/weavescope/manifests/scope-app-rc.yaml # only if you want to run scope in standalone mode
kubectl create -f $HOME/.helm/workspace/charts/weavescope/manifests/scope-app-svc.yaml # only if you want to run scope in standalone mode
