This PR fixes links where the target is a redirection. The special case is about minikube, which has been deleted recently. The dangling link now points to `/docs/tasks/tools/` which makes no sense. This PR change the target for `minikube` to `https://minikube.sigs.k8s.io/docs/`.

Weave Net for NetworkPolicy | task | 50 |
This page shows how to use Weave Net for NetworkPolicy.
{{% heading "prerequisites" %}}
You need to have a Kubernetes cluster. Follow the kubeadm getting started guide to bootstrap one.
Install the Weave Net addon
Follow the Integrating Kubernetes via the Addon guide.
The Weave Net addon for Kubernetes comes with a
Network Policy Controller
that automatically monitors Kubernetes for any NetworkPolicy annotations on all
namespaces and configures iptables rules to allow or block traffic as directed by the policies.
Test the installation
Verify that the weave works.
Enter the following command:
kubectl get pods -n kube-system -o wide
The output is similar to this:
NAME READY STATUS RESTARTS AGE IP NODE
weave-net-1t1qg 2/2 Running 0 9d 192.168.2.10 worknode3
weave-net-231d7 2/2 Running 1 7d 10.2.0.17 worknodegpu
weave-net-7nmwt 2/2 Running 3 9d 192.168.2.131 masternode
weave-net-pmw8w 2/2 Running 0 9d 192.168.2.216 worknode2
Each Node has a weave Pod, and all Pods are Running and 2/2 READY. (2/2 means that each Pod has weave and weave-npc.)
