A.support soft link better
before this patch
"kubectl cp" command will copy the soft link to destination as an empty regular file
after this patch
"kubectl cp" command will behave the same as tar command
this patch improves it on both from container and to container
B.fix some bugs
1.from container to host
a.when copy a file ends with '/', it will cause a panic.
for example, container gakki has a regular file /tmp/test, then run command
kubectl cp gakki:/tmp/test/ /tmp
panic happens
b.when copy a file which does not exist in container, the command ends up without
any error information
2.from host to container
a.when run command like
kubectl cp "" gakki:/tmp
it will try cp current directory to container, in other words, this command works
the same as kubectl cp . gakki:/tmp
b.current cp command will omit an empty directory

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.
