If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. Fix calico network policy for opensource. For https://github.com/kubernetes/features/issues/286 This PR: 1) Add `NON_MASTER_NODE_LABELS` env, and only apply calico node label on non-master nodes. 2) Set ip masq rules in cloud init, so that we don't need the ip masq agent. @dchen1107 @dnardo As we discussed. 3) Let master use `${NETWORK_PROVIDER}` instead of fixed cni, because we won't run calico node agent on master. The master network should be configured separately (kubenet by default). With this PR, I could bring up a cluster with `NETWORK_POLICY_PROVIDER=calico` on GCE now. ```console $ cluster/kubectl.sh get pods --all-namespaces NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-node-9bxbv 2/2 Running 0 13m kube-system calico-node-kjxtw 2/2 Running 0 13m kube-system calico-node-vertical-autoscaler-67fb4f45bd-hcjmw 1/1 Running 0 16m kube-system calico-node-xs2s2 2/2 Running 0 13m kube-system calico-typha-7c4d876ddf-d4dtx 1/1 Running 0 15m kube-system calico-typha-horizontal-autoscaler-5f477cdc66-qwwph 1/1 Running 0 16m kube-system calico-typha-vertical-autoscaler-58f7d686f7-pn72s 1/1 Running 0 16m kube-system etcd-empty-dir-cleanup-e2e-test-lantaol-master 1/1 Running 0 16m kube-system etcd-server-e2e-test-lantaol-master 1/1 Running 0 16m kube-system etcd-server-events-e2e-test-lantaol-master 1/1 Running 0 16m kube-system event-exporter-v0.1.7-9d4dbb69c-m76v5 2/2 Running 0 16m kube-system fluentd-gcp-v2.0.10-25dmf 2/2 Running 0 16m kube-system fluentd-gcp-v2.0.10-kgxsk 2/2 Running 0 16m kube-system fluentd-gcp-v2.0.10-p75xg 2/2 Running 0 16m kube-system fluentd-gcp-v2.0.10-xzh77 2/2 Running 0 16m kube-system heapster-v1.5.0-beta.0-5cf4d9dff7-dmvm7 4/4 Running 0 13m kube-system kube-addon-manager-e2e-test-lantaol-master 1/1 Running 0 15m kube-system kube-apiserver-e2e-test-lantaol-master 1/1 Running 0 16m kube-system kube-controller-manager-e2e-test-lantaol-master 1/1 Running 0 16m kube-system kube-dns-79bdcb6c9f-2bpc8 3/3 Running 0 15m kube-system kube-dns-79bdcb6c9f-gr686 3/3 Running 0 16m kube-system kube-dns-autoscaler-996dcfc9d-pfs4s 1/1 Running 0 16m kube-system kube-proxy-e2e-test-lantaol-minion-group-3khw 1/1 Running 0 16m kube-system kube-proxy-e2e-test-lantaol-minion-group-6878 1/1 Running 0 16m kube-system kube-proxy-e2e-test-lantaol-minion-group-j9rq 1/1 Running 0 16m kube-system kube-scheduler-e2e-test-lantaol-master 1/1 Running 0 16m kube-system kubernetes-dashboard-765c6f47bd-lsw5r 1/1 Running 0 16m kube-system l7-default-backend-6d477bf555-x54zf 1/1 Running 0 16m kube-system l7-lb-controller-v0.9.7-e2e-test-lantaol-master 1/1 Running 0 16m kube-system metrics-server-v0.2.0-9c4f8c48d-gkl79 2/2 Running 0 13m kube-system monitoring-influxdb-grafana-v4-54df94856c-krkvb 2/2 Running 0 16m kube-system rescheduler-v0.3.1-e2e-test-lantaol-master 1/1 Running 0 16m ``` **Note that with this PR, master node will be using kubenet by default.

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.
