Automatic merge from submit-queue (batch tested with PRs 65388, 64995). 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>. Always create kubeClusterIPSet in ipvs proxier **What this PR does / why we need it**: This PR creates the kubeClusterIPSet ipset even if kube-proxy is started without masqueradeAll and clusterCIDR. This is necessary to masquerade traffic sent to a clusterIP from the host network namespace. The code to do so is actually already present here: https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/ipvs/proxier.go#L1220-L1244 However the second else (neither masqueradeAll nor clusterCIDR are set) cannot be used because, before this PR, the initial test `if !proxier.ipsetList[kubeClusterIPSet].isEmpty()` can never return true when masqueradeAll and clusterCIDR are not set because kubeClusterIPSet is empty. **Which issue(s) this PR fixes** Fixes #65158 ```release-note Allow access to ClusterIP from the host network namespace when kube-proxy is started in IPVS mode without either masqueradeAll or clusterCIDR flags ``` **Additional comment** Issue #65158 is closed because ClusterIP access from the host has already fixed in master, except for the case described here (no masquerade flag). More detail in the issue. |

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
For the full story, 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.
