Automatic merge from submit-queue (batch tested with PRs 49850, 47782, 50595, 50730, 51341) Paramaterize `stickyMaxAgeMinutes` for service in API **What this PR does / why we need it**: Currently I find `stickyMaxAgeMinutes` for a session affinity type service is hard code to 180min. There is a TODO comment, see https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/iptables/proxier.go#L205 I think the seesion sticky max time varies from service to service and users may not aware of it since it's hard coded in all proxier.go - iptables, userspace and winuserspace. Once we parameterize it in API, users can set/get the values for their different services. Perhaps, we can introduce a new field `api.ClientIPAffinityConfig` in `api.ServiceSpec`. There is an initial discussion about it in sig-network group. See, https://groups.google.com/forum/#!topic/kubernetes-sig-network/i-LkeHrjs80 **Which issue this PR fixes**: fixes #49831 **Special notes for your reviewer**: **Release note**: ```release-note Paramaterize session affinity timeout seconds in service API for Client IP based session affinity. ```
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.
