Changing import statements or a tentative `go +get` can result in stale dependencies. + +The `test-vendor` verifies that it was used when run locally or in a +pre-merge CI job. If a `vendor` directory is present, it will also +verify that it's content is up-to-date. + +The `vendor` directory is optional. It is still present in projects +because it avoids downloading sources during CI builds. If this is no +longer deemed necessary, then a project can also remove the directory. + +Conversion of a repository that uses `dep` to `go mod` can be done with: + + GO111MODULE=on go mod init + release-tools/go-get-kubernetes.sh + GO111MODULE=on go mod tidy + GO111MODULE=on go mod vendor + git rm -f Gopkg.toml Gopkg.lock + git add go.mod go.sum vendor + +### Updating Kubernetes dependencies + +When using packages that are part of the Kubernetes source code, the +commands above are not enough because the [lack of semantic +versioning](https://github.com/kubernetes/kubernetes/issues/72638) +prevents `go mod` from finding newer releases.

Jobs should be actively monitored to find and fix failures in sidecars and + infrastructure changes early in the development cycle. Test failures are sent + to kubernetes-sig-storage-test-failures@googlegroups.com. +1. "-on-master" jobs are the closest reflection to the new Kubernetes version. +1. Fixes to our prow.sh CI script can be tested in the [CSI hostpath + repo](https://github.com/kubernetes-csi/csi-driver-host-path) by modifying + [prow.sh](https://github.com/kubernetes-csi/csi-driver-host-path/blob/master/release-tools/prow.sh) + along with any overrides in + [.prow.sh](https://github.com/kubernetes-csi/csi-driver-host-path/blob/master/.prow.sh) + to mirror the failing environment. Once e2e tests are passing (verify-unit tests + will fail), then the prow.sh changes can be submitted to [csi-release-tools](https://github.com/kubernetes-csi/csi-release-tools). +1. Changes can then be updated in all the sidecar repos and hostpath driver repo + by following the [update + instructions](https://github.com/kubernetes-csi/csi-release-tools/blob/master/README.md#sharing-and-updating). +1. New pull and CI jobs are configured by adding new K8s versions to the top of + [gen-jobs.sh](https://github.com/kubernetes/test-infra/blob/master/config/jobs/kubernetes-csi/gen-jobs.sh). + New pull jobs that have been unverified should be initially made optional by + setting the new K8s version as + [experimental](https://github.com/kubernetes/test-infra/blob/a1858f46d6014480b130789df58b230a49203a64/config/jobs/kubernetes-csi/gen-jobs.sh#L40). +1.

Compare the generated output to the new commits for the release to check if + any notable change missed a release note. +1. Reword release notes as needed. Make sure to check notes for breaking + changes and deprecations. +1. If release is a new major/minor version, create a new `CHANGELOG-..md` + file. Otherwise, add the release notes to the top of the existing CHANGELOG + file for that minor version. +1. Submit a PR for the CHANGELOG changes. +1. Submit a PR for README changes, in particular, Compatibility, Feature status, + and any other sections that may need updating. +1. Check that all [canary CI + jobs](https://k8s-testgrid.appspot.com/sig-storage-csi-ci) are passing, + and that test coverage is adequate for the changes that are going into the release. +1. Make sure that no new PRs have merged in the meantime, and no PRs are in + flight and soon to be merged. +1. Create a new release following a previous release as a template. Be sure to select the correct + branch. This requires Github release permissions as required by the prerequisites. + [external-provisioner example](https://github.com/kubernetes-csi/external-provisioner/releases/new) +1. If release was a new major/minor version, create a new `release-` + branch at that commit. +1. Check [image build status](https://k8s-testgrid.appspot.com/sig-storage-image-build). +1.
