Kubernetes Release Notes Generator

This directory contains a tool called release-notes and a set of library utilities at which aim to provide a simple and extensible set of tools for fetching, contextualizing, and rendering release notes for the Kubernetes repository.

Install

The simplest way to install the release-notes CLI is via go install:

$ go install k8s.io/release/cmd/release-notes@latest

This will install release-notes to $(go env GOPATH)/bin/release-notes.

Usage

To generate release notes for a commit range, run:

$ export GITHUB_TOKEN=a_github_api_token
$ release-notes \
  --start-sha 02dc3d713dd7f945a8b6f7ef3e008f3d29c2d549 \
  --end-sha   23649560c060ad6cd82da8da42302f8f7e38cf1e

level=info timestamp=2019-07-30T04:02:43.8454168Z caller=notes.go:446 msg="[1/1679 - 0.06%]"
...

level=info timestamp=2019-07-30T04:11:38.8033378Z caller=main.go:159 msg="got the commits, performing rendering"

You can also generate the raw notes data into JSON. You can then use a variety of tools (such as jq) to slice and dice the output:

[
  {
    "text": "fixed incorrect OpenAPI schema for CustomResourceDefinition objects",
    "author": "liggitt",
    "author_url": "https://github.com/liggitt",
    "pr_url": "https://github.com/kubernetes/kubernetes/pull/65256",
    "pr_number": 65256,
    "kinds": [
      "bug"
    ],
    "sigs": [
      "api-machinery"
    ]
  }
]

if you would like to debug a run, use the --debug flag:

$ export GITHUB_TOKEN=a_github_api_token
$ release-notes \
  --start-sha 02dc3d713dd7f945a8b6f7ef3e008f3d29c2d549 \
  --end-sha   23649560c060ad6cd82da8da42302f8f7e38cf1e \
  --debug

FAQ

What do generated notes look like?

Check out the rendering of 1.11's release notes here.

What formats are supported?

Right now the tool can output release notes in Markdown and JSON. The tool also supports arbitrary formats using go-templates. The template has access to fields in the Document struct. For an example, see the default markdown template (pkg/notes/internal/template.go) used to render the stock format.
