| # 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 maintainence, 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 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 | ||
| [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. | ||
| [Example](https://github.com/kubernetes/test-infra/pull/15055) | ||
| 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 [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. | ||
| ``` | ||
| GITHUB_TOKEN=<token> ./release-notes --start-sha=0ed6978fd199e3ca10326b82b4b8b8e916211c9b --end-sha=3cb3d2f18ed8cb40371c6d8886edcabd1f27e7b9 \ | ||
| --github-org=kubernetes-csi --github-repo=external-attacher -branch=master -output out.md | ||
| ``` | ||
| * `--start-sha` should point to the last release from the same branch. For | ||
| example: | ||
| * `1.X-1.0` tag when releasing `1.X.0` | ||
| * `1.X.Y-1` tag when releasing `1.X.Y` | ||
| 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. 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) |
