Automatic merge from submit-queue (batch tested with PRs 63445, 63820). 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>. core v1: deprecate the gitRepo volume type gitRepo stopped accepting new features nearly 2 years ago https://github.com/kubernetes/kubernetes/issues/17676#issuecomment-228650586 and today this behavior can easily be achieved through an init container. The kubelet shelling out to git in the host namespace can also be a security issue on un-trusted repos, as was demonstrated by [CVE-2017-1000117](https://groups.google.com/forum/#!topic/kubernetes-announce/CTLXJ74cu8M). Our own documentation even alludes to this volume type being removed in the future: > In the future, such volumes may be moved to an even more decoupled model, rather than extending the Kubernetes API for every such use case. https://kubernetes.io/docs/concepts/storage/volumes/#gitrepo Closes https://github.com/kubernetes/kubernetes/issues/60999 ```release-note-action-required The GitRepo volume type is deprecated. To provision a container with a git repo, mount an EmptyDir into an InitContainer that clones the repo using git, then mount the EmptyDir into the Pod's container. ``` /release-note-action-required Instead of this: ```yaml apiVersion: v1 kind: Pod metadata: name: server spec: containers: - image: nginx name: nginx volumeMounts: - mountPath: /mypath name: git-volume volumes: - name: git-volume gitRepo: repository: "git@somewhere:me/my-git-repository.git" revision: "22f1d8406d464b0c0874075539c1f2e96c253775" ``` Do this: ```yaml apiVersion: v1 kind: ConfigMap metadata: name: git-clone data: git-clone.sh: | #!/bin/sh -e git clone $1 $3 cd $3 git reset --hard $2 --- apiVersion: v1 kind: Pod metadata: name: server spec: initContainers: - name: git-clone image: alpine/git # Any image with git will do command: - /usr/local/git/git-clone.sh args: - "https://somewhere/me/my-git-repository.git" - "22f1d8406d464b0c0874075539c1f2e96c253775" - "/mypath" volumeMounts: - name: git-clone mountPath: /usr/local/git - name: git-repo mountPath: /mypath containers: - image: nginx name: nginx volumeMounts: - mountPath: /mypath name: git-volume volumes: - name: git-volume emptyDir: {} - name: git-clone configMap: name: git-clone defaultMode: 0755 ``` |

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
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.
