Background: Before this change, DeltaFIFO emits the Sync DeltaType on Resync() and Replace(). Seperately, the SharedInformer will only pass that event on to handlers that have a ResyncInterval and are due for Resync. This can cause updates to be lost if an object changes as part of the Replace(), as it may be incorrectly discarded if the handler does not want a Resync. What this change does: Creates a new DeltaType, Replaced, which is emitted by DeltaFIFO on Replace(). For backwards compatability concerns, the old behavior of always emitting Sync is preserved unless explicity overridden. As a result, if an object changes (or is added) on Replace(), now all SharedInformer handlers will get a correct Add() or Update() notification. One additional side-effect is that handlers which do not ever want Resyncs will now see them for all objects that have not changed during the Replace.
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.
