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 ``` |
