Benjamin Pineau ee7cd252e8 Azure: fix node removal race condition on VMSS deletion
When a VMSS is being deleted, instances are removed first. The VMSS
itself will disappear once empty. That delay is generally enough for
kube-controller-manager to delete the corresponding k8s nodes, but
might not when busy or throttled (for instance).

If kubernetes nodes remains after their backing VMSS were removed, Azure
cloud-provider will fail listing that VMSS VMs, and downstream callers
(ie. `InstanceExistsByProviderID`) won't account those errors for a
missing instance. The nodes will remain (still considered as "existing"),
and controller-manager will indefinitely retry to VMSS VMs list it,
draining API calls quotas, potentially causing throttling.

In practice a missing scale set implies instances attributed to that
VMSS don't exists either: `InstanceExistsByProviderID` (part of the
general cloud provider interface) should return false in that case.

Kubernetes

GoDoc Widget CII Best Practices


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.
