Move NetworkPolicy to v1
Move NetworkPolicy to v1
@kubernetes/sig-network-misc
**Release note**:
```release-note
NetworkPolicy has been moved from `extensions/v1beta1` to the new
`networking.k8s.io/v1` API group. The structure remains unchanged from
the beta1 API.
The `net.beta.kubernetes.io/network-policy` annotation on Namespaces
to opt in to isolation has been removed. Instead, isolation is now
determined at a per-pod level, with pods being isolated if there is
any NetworkPolicy whose spec.podSelector targets them. Pods that are
targeted by NetworkPolicies accept traffic that is accepted by any of
the NetworkPolicies (and nothing else), and pods that are not targeted
by any NetworkPolicy accept all traffic by default.
Action Required:
When upgrading to Kubernetes 1.7 (and a network plugin that supports
the new NetworkPolicy v1 semantics), to ensure full behavioral
compatibility with v1beta1:
1. In Namespaces that previously had the "DefaultDeny" annotation,
you can create equivalent v1 semantics by creating a
NetworkPolicy that matches all pods but does not allow any
traffic:
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: default-deny
spec:
podSelector:
This will ensure that pods that aren't match by any other
NetworkPolicy will continue to be fully-isolated, as they were
before.
2. In Namespaces that previously did not have the "DefaultDeny"
annotation, you should delete any existing NetworkPolicy
objects. These would have had no effect before, but with v1
semantics they might cause some traffic to be blocked that you
didn't intend to be blocked.

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts, providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
If you are less impatient, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
