Fix pointer receiver handling in queryparams marshaler **What this PR does / why we need it**: `Time.MarshalQueryParameter()` and `Time.MarshalJSON()` try to handle nil pointer object (they call `t.IsZero()` which checks if t == nil) but fail because receiver is not a pointer so the dereference needed to pass it as receiver to these methods fails with npe. In practice this happens with `Unstructured.SetDeletionTimestamp(Unstructured.GetDeletionTimestamp())`. Here is the stacktrace of the failing test if receiver is not a pointer. ```go 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=0x8 pc=0x1407969] goroutine 22 [running]: testing.tRunner.func1(0xc4204f0680) /usr/local/Cellar/go/1.8/libexec/src/testing/testing.go:622 +0x29d panic(0x1485a80, 0x1782bc0) /usr/local/Cellar/go/1.8/libexec/src/runtime/panic.go:489 +0x2cf k8s.io/kubernetes/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/unstructured.(*Unstructured).SetDeletionTimestamp(0xc420030790, 0x0) /Users/ash2k/gopath/src/k8s.io/kubernetes/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/unstructured/unstructured.go:387 +0x29 k8s.io/kubernetes/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/unstructured.TestNilDeletionTimestamp(0xc4204f0680) /Users/ash2k/gopath/src/k8s.io/kubernetes/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/unstructured/unstructured_test.go:40 +0x4c ```
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.
