+Dependencies and vendoring
+--------------------------
+
+Most projects will (eventually) use `go mod` to manage
+dependencies. `dep` is also still supported by `csi-release-tools`,
+but not documented here because it's not recommended anymore.
+
+The usual instructions for using [go
+modules](https://github.com/golang/go/wiki/Modules) apply. Here's a cheat sheet
+for some of the relevant commands:
+- list available updates: `GO111MODULE=on go list -u -m all`
+- update or add a single dependency: `GO111MODULE=on go get <package>`
+- update all dependencies to their next minor or patch release:
+  `GO111MODULE=on go get ./...` (add `-u=patch` to limit to patch
+  releases)
+- lock onto a specific version: `GO111MODULE=on go get <package>@<version>`
+- clean up `go.mod`: `GO111MODULE=on go mod tidy`
+- update vendor directory: `GO111MODULE=on go mod vendor`
+
+`GO111MODULE=on` can be left out when using Go >= 1.13 or when the
+source is checked out outside of `$GOPATH`.
+
+`go mod tidy` must be used to ensure that the listed dependencies are
+really still needed. Changing import statements or a tentative `go
+get` can result in stale dependencies.
+
+The `test-vendor` verifies that it was used when run locally or in a
+pre-merge CI job. If a `vendor` directory is present, it will also
+verify that it's content is up-to-date.
+
+The `vendor` directory is optional. It is still present in projects
+because it avoids downloading sources during CI builds. If this is no
+longer deemed necessary, then a project can also remove the directory.
+
+Conversion of a repository that uses `dep` to `go mod` can be done with:
+
+    GO111MODULE=on go mod init
+    release-tools/go-get-kubernetes.sh <current Kubernetes version from Gopkg.toml>
+    GO111MODULE=on go mod tidy
+    GO111MODULE=on go mod vendor
+    git rm -f Gopkg.toml Gopkg.lock
+    git add go.mod go.sum vendor
+
+### Updating Kubernetes dependencies
+
+When using packages that are part of the Kubernetes source code, the
+commands above are not enough because the [lack of semantic
+versioning](https://github.com/kubernetes/kubernetes/issues/72638)
+prevents `go mod` from finding newer releases. Importing directly from
+`kubernetes/kubernetes` also needs `replace` statements to override
+the fake `v0.0.0` versions
+(https://github.com/kubernetes/kubernetes/issues/79384). The
+`go-get-kubernetes.sh` script can be used to update all packages in
+lockstep to a different Kubernetes version. Example usage:
+```
+$ ./release-tools/go-get-kubernetes.sh 1.16.4
+```

+# Sidecar Release Process
+
+This page describes the process for releasing a kubernetes-csi sidecar.
+
+## Prerequisites
+
+The release manager must:
+
+* Be a member of the kubernetes-csi organization. Open an
+  [issue](https://github.com/kubernetes/org/issues/new?assignees=&labels=area%2Fgithub-membership&template=membership.md&title=REQUEST%3A+New+membership+for+%3Cyour-GH-handle%3E) in
+  kubernetes/org to request membership
+* Be a top level approver for the repository. To become a top level approver,
+  the candidate must demonstrate ownership and deep knowledge of the repository
+  through active maintenance, responding to and fixing issues, reviewing PRs,
+  test triage.
+* Be part of the maintainers or admin group for the repository. admin is a
+  superset of maintainers, only maintainers level is required for cutting a
+  release.  Membership can be requested by submitting a PR to kubernetes/org.
+  [Example](https://github.com/kubernetes/org/pull/1467)
+
+## Updating CI Jobs
+Whenever a new Kubernetes minor version is released, our kubernetes-csi CI jobs
+must be updated.
+
+[Our CI jobs](https://k8s-testgrid.appspot.com/sig-storage-csi-ci) have the
+naming convention `<hostpath-deployment-version>-on-<kubernetes-version>`.
+
+1. 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 [email protected].
+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. Once new pull and CI jobs have been verified, and the new Kubernetes version
+   is released, we can make the optional jobs required, and also remove the
+   Kubernetes versions that are no longer supported.
+
+## Release Process
+1. Identify all issues and ongoing PRs that should go into the release, and
+  drive them to resolution.
+1. Download v2.8+ [K8s release notes
+  generator](https://github.com/kubernetes/release/tree/master/cmd/release-notes)
+1. Generate release notes for the release. Replace arguments with the relevant
+  information.
+    * Clean up old cached information (also needed if you are generating release
+      notes for multiple repos)
+      ```bash
+      rm -rf /tmp/k8s-repo
+      ```
+    * For new minor releases on master:
+        ```bash
+        GITHUB_TOKEN=<token> release-notes --discover=mergebase-to-latest
+        --github-org=kubernetes-csi --github-repo=external-provisioner
+        --required-author="" --output out.md
+        ```
+    * For new patch releases on a release branch:
+        ```bash
+        GITHUB_TOKEN=<token> release-notes --discover=patch-to-latest --branch=release-1.1
+        --github-org=kubernetes-csi --github-repo=external-provisioner
+        --required-author="" --output out.md
+        ```
+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-<major>.<minor>.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-<minor>`
+   branch at that commit.
+1. Check [image build status](https://k8s-testgrid.appspot.com/sig-storage-image-build).
+1. Promote images from k8s-staging-sig-storage to k8s.gcr.io/sig-storage. From
+   the [k8s image
+   repo](https://github.com/kubernetes/k8s.io/tree/master/k8s.gcr.io/images/k8s-staging-sig-storage),
+   run `./generate.sh > images.yaml`, and send a PR with the updated images.
+   Once merged, the image promoter will copy the images from staging to prod.
+1. Update [kubernetes-csi/docs](https://github.com/kubernetes-csi/docs) sidecar
+   and feature pages with the new released version.
+1. After all the sidecars have been released, update
+   CSI hostpath driver with the new sidecars in the [CSI repo](https://github.com/kubernetes-csi/csi-driver-host-path/tree/master/deploy)
+   and [k/k
+   in-tree](https://github.com/kubernetes/kubernetes/tree/master/test/e2e/testing-manifests/storage-csi/hostpath/hostpath)
+
+## Adding support for a new Kubernetes release
+
+1. Add the new release to `k8s_versions` in
+   https://github.com/kubernetes/test-infra/blob/090dec5dd535d5f61b7ba52e671a810f5fc13dfd/config/jobs/kubernetes-csi/gen-jobs.sh#L25
+   to enable generating a job for it. Set `experimental_k8s_version`
+   in
+   https://github.com/kubernetes/test-infra/blob/090dec5dd535d5f61b7ba52e671a810f5fc13dfd/config/jobs/kubernetes-csi/gen-jobs.sh#L40
+   to ensure that the new jobs aren't run for PRs unless explicitly
+   requested. Generate and submit the new jobs.
+1. Create a test PR to try out the new job in some repo with `/test
+   pull-kubernetes-csi-<repo>-<x.y>-on-kubernetes-<x.y>` where x.y
+   matches the Kubernetes release. Alternatively, run .prow.sh in that
+   repo locally with `CSI_PROW_KUBERNETES_VERSION=x.y.z`.
+1. Optional: update to a [new
+   release](https://github.com/kubernetes-sigs/kind/tags) of kind with
+   pre-built images for the new Kubernetes release. This is optional
+   if the current version of kind is able to build images for the new
+   Kubernetes release. However, jobs require less resources when they
+   don't need to build those images from the Kubernetes source code.
+   This change needs to be tried out in a PR against a component
+   first, then get submitted against csi-release-tools.
+1. Optional: propagate the updated csi-release-tools to all components
+   with the script from
+   https://github.com/kubernetes-csi/csi-release-tools/issues/7#issuecomment-707025402
+1. Once it is likely to work in all components, unset
+   `experimental_k8s_version` and submit the updated jobs.
+1. Once all sidecars for the new Kubernetes release are released,
+   either bump the version number of the images in the existing
+   [csi-driver-host-path
+   deployments](https://github.com/kubernetes-csi/csi-driver-host-path/tree/master/deploy)
+   and/or create a new deployment, depending on what Kubernetes
+   release an updated sidecar is compatible with. If no new deployment
+   is needed, then add a symlink to document that there intentionally
+   isn't a separate deployment. This symlink is not needed for Prow
+   testing because that will use "kubernetes-latest" as fallback.
+   Update that link when creating a new deployment.
+1. Create a new csi-driver-host-path release.
+1. Bump `CSI_PROW_DRIVER_VERSION` in prow.sh to that new release and
+   (eventually) roll that change out to all repos by updating
+   `release-tools` in them. This is used when testing manually. The
+   Prow jobs override that value, so also update
+   `hostpath_driver_version` in
+   https://github.com/kubernetes/test-infra/blob/91b04e6af3a40a9bcff25aa030850a4721e2dd2b/config/jobs/kubernetes-csi/gen-jobs.sh#L46-L47
