This fixes a bug that occurred when a Service was rapidly recreated. This relied on an unfortunate series of events: 1. When the Service is deleted, the EndpointSlice controller removes it from the EndpointSliceTracker along with any associated EndpointSlices. 2. When the Service is recreated, the EndpointSlice controller sees that there are still appropriate EndpointSlices for the Service and does nothing. (They have not yet been garbage collected). 3. When the EndpointSlice is deleted, the EndpointSlice controller checks with the EndpointSliceTracker to see if it thinks we should have this EndpointSlice. This check was intended to ensure we wouldn't requeue a Service every time we delete an EndpointSlice for it. This adds a check in reconciler to ensure that EndpointSlices it is working with are owned by a Service with a matching UID. If not, it will mark those EndpointSlices for deletion (assuming they're about to be garbage collected anyway) and create new EndpointSlices.
Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts. It provides 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 your company 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 use Kubernetes code as a library in other applications, see the list of published components.
Use of the k8s.io/kubernetes module or k8s.io/kubernetes/... packages as libraries is not supported.
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.
mkdir -p $GOPATH/src/k8s.io
cd $GOPATH/src/k8s.io
git clone https://github.com/kubernetes/kubernetes
cd 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.
