Automatic merge from submit-queue (batch tested with PRs 49409, 49352, 49266, 48418) Use the yet uninitialized informer factory `informerFactory` has been started already but the `factory.equivalencePodCache` field has not been initialized yet (done below by `.Create()`). So when Service informer calls `onServiceAdd()`, it tries to access this field and crashes with npe. The fix is to use `informerFactory2`. It is a race between listeners called by informer and `.Create()`. Do we run unit/integration tests with race detector switched off? ``` panic: runtime error: invalid memory address or nil pointer dereference [recovered] panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x14c2c2f] goroutine 11688 [running]: k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/util/runtime.HandleCrash(0x0, 0x0, 0x0) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/util/runtime/runtime.go:58 +0x126 panic(0x28f5f00, 0x61621c0) /usr/local/go/src/runtime/panic.go:489 +0x2cf k8s.io/kubernetes/plugin/pkg/scheduler/core.(*EquivalenceCache).InvalidateCachedPredicateItemOfAllNodes(0x0, 0xc4202a9020) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/plugin/pkg/scheduler/core/equivalence_cache.go:141 +0x5f k8s.io/kubernetes/plugin/pkg/scheduler/factory.(*ConfigFactory).onServiceAdd(0xc424ad5950, 0x2cf6fc0, 0xc4249c05a0) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/plugin/pkg/scheduler/factory/factory.go:347 +0x53 k8s.io/kubernetes/plugin/pkg/scheduler/factory.(*ConfigFactory).(k8s.io/kubernetes/plugin/pkg/scheduler/factory.onServiceAdd)-fm(0x2cf6fc0, 0xc4249c05a0) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/plugin/pkg/scheduler/factory/factory.go:247 +0x3e k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache.ResourceEventHandlerFuncs.OnAdd(0xc423a47310, 0xc423a47320, 0xc423a47330, 0x2cf6fc0, 0xc4249c05a0) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache/controller.go:195 +0x49 k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache.(*ResourceEventHandlerFuncs).OnAdd(0xc423938ce0, 0x2cf6fc0, 0xc4249c05a0) <autogenerated>:54 +0x73 k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache.(*processorListener).run(0xc424a698b0) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache/shared_informer.go:544 +0x287 k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache.(*processorListener).(k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache.run)-fm() /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/vendor/k8s.io/client-go/tools/cache/shared_informer.go:380 +0x2a k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/util/wait.(*Group).Start.func1(0xc424a87868, 0xc423a47370) /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/util/wait/wait.go:71 +0x4f created by k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/util/wait.(*Group).Start /go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/vendor/k8s.io/apimachinery/pkg/util/wait/wait.go:72 +0x62 ``` **Special notes for your reviewer**: Found while working on #47045. **Release note**: ```release-note NONE ```
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.
