If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. preserve specified destination path **Release note**: ```release-note "kubectl cp" updated to honor destination names ``` **Before** ``` $ kubectl cp foo_dir pod_name:/tmp/bar_dir $ kubectl exec pod_name -it -- /bin/sh sh-4.2$ sh-4.2$ ls /tmp sh-4.2$ foo_dir ``` **After** ``` $ kubectl cp foo_dir pod_name:/tmp/bar_dir $ kubectl exec pod_name -it -- /bin/sh sh-4.2$ sh-4.2$ ls /tmp sh-4.2$ bar_dir ``` **Notable changes to `kubectl cp` After This Patch** - Copying a directory `bar_dir` to an existing directory in the pod will copy the directory itself, rather than just the file contents: ```bash *Before* > remote-pod-shell$ ls /tmp existing_remote_dir $ kubectl cp ./my/local/awesome_dir mypod:/tmp/existing_remote_dir > remote-pod-shell$ ls /tmp existing_remote_dir awesome_dir ``` ```bash *After* > remote-pod-shell$ ls /tmp existing_remote_dir $ kubectl cp ./my/local/awesome_dir mypod:/tmp/existing_remote_dir > remote-pod-shell$ ls /tmp existing_remote_dir > remote-pod-shell$ ls /tmp/existing_remote_dir awesome_dir ``` ``` *Before*: Directory contents were merged if a local and remote directory shared the same name *After*: A new name will be honored for the copied local directory on the remote pod. If a new name was not specified for the local directory being copied, and it shares the same name as an already-existing directory on the pod, current behavior will follow and its contents will be added to those of the already-existing directory. ``` ``` *Before*: If a trailing slash (e.g. kubectl cp ./local/dir pod:/tmp) was not added to a directory name in the destination path (...:/tmp vs /tmp/...), when copying to a pod, `kubectl` would attempt to copy the local directory under the parent of the remote directory rather than inside of it. *After*: Slashes do not alter the behavior of the command, or destination of the intended source file or directory. With a command such as (kubectl cp ./local_dir pod:/tmp), `local_dir` would be copied inside of <pod:/tmp> (an error is returned if pod:/tmp is a file). ``` Related downstream bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1469411 @fabianofranz @kubernetes/sig-cli-misc |

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.
