Ambassador Documentation

The documentation in this repository is built with Gatsby, which gives us control and flexibility over the layout.

Contributing

We welcome all contributions! See LICENSE for applicable terms and conditions.

Authoring Documentation

If you're authoring the documentation, just edit the Markdown files. You can use GitHub to preview the Markdown.

Strings like $variable$ are substituted with the values defined in versions.yml.

The doc-links.yml file is the table of contents (TOC) that appears on the left sidebar.

The aes-pages.yml file identifies which pages should be marked as "Ambassador Edge Stack" pages.

Documentation Infrastructure Notes

The docs in this repository can be "vendored" into other repositories using git subtree. Repositories that do this are encouraged to include some kind of convenience tooling to make syncing the docs easier. For example, the following Makefile snippet:

pull-docs: ## Update ./docs from https://github.com/datawire/ambassador-docs
	git subtree pull --prefix=docs https://github.com/datawire/ambassador-docs.git master
push-docs: ## Publish ./docs to https://github.com/datawire/ambassador-docs
	git subtree push --prefix=docs [email protected]:datawire/ambassador-docs.git master
.PHONY: pull-docs push-docs

The (private) getambassador.io.git repository contains the Gatsby-based toolchain that compiles the docs into website at https://www.getambassador.io/.

Other repositories that include the docs as a subtree should get in the habit of doing a git subtree pull from their master branch periodically. Documentation for code changes can then be committed right along-side the code changes. When a release is cut, and you are ready to publicize it, simply do a git subtree push.

Adding Release Notes

To add a Release Notes page for a product version, you should:

  1. Add a releaseNotes.yml file to the folder for that version of the product under ambassador-docs/docs. A template for this file can be found here:
# This file should be placed in the folder for the version of the
# product that's meant to be documented. A `/release-notes` page will
# be automatically generated and populated at build time.
#
# Note that an entry needs to be added to the `doc-links.yml` file in
# order to surface the release notes in the table of contents.
#
# The YAML in this file should contain:
#
# changelog: An (optional) URL to the CHANGELOG for the product.
# items: An array of releases with the following attributes:
#     - version: The (optional) version number of the release, if applicable.
#     - date: The date of the release in the format YYYY-MM-DD.
#     - notes: An array of noteworthy changes included in the release, each having the following attributes:
#         - type: The type of change, one of `bugfix`, `feature`, `security` or `change`.
#         - title: A short title of the noteworthy change.
#         - body: >-
#             Two or three sentences describing the change and why it
#             is noteworthy.  This is HTML, not plain text or
#             markdown.  It is handy to use YAML's ">-" feature to
#             allow line-wrapping.
#         - image: >-
#             The URL of an image that visually represents the
#             noteworthy change.  This path is relative to the
#             `release-notes` directory; if this file is
#             `FOO/releaseNotes.yml`, then the image paths are
#             relative to `FOO/release-notes/`.
#         - docs: The path to the documentation page where additional information can be found.

items:
  - version: 1.13.4
    date: '2021-05-13'
    notes:
      - type: security
        title: Envoy 1.15.5
        body: >-
          Emissary-ingress 1.13.4 and Edge Stack 1.13.4 have been
          updated to Envoy 1.15.5, which addresses a high severity
          security vulnerability (CVE-2021-29492). Edge Stack and
          Emissary-ingress can now be configured to reject client
          requests that contain escaped slashes.

        docs: topics/running/ambassador/#rejecting-client-requests-with-escaped-slashes
  1. Add an entry to the doc-links.yml file to surface the release notes in the table of contents:
- title: Release Notes
  link: /release-notes
  1. If images need to be added, the images should be included in the ambassador-docs/public folder.
