KONG's Documentation Website

This repository contains the source content and code for Kong's documentation website. It's built using Jekyll and deployed with Netlify.

Here are some things to know before you get started:

• We're beginner-friendly. Whether you're a Technical Writer learning about docs-as-code or an engineer practicing your documentation skills, we welcome your involvement. If you'd like to contribute and don't have something in mind already, head on over to Issues. We've added good first issue labels on beginner-friendly issues.

• We need more help in some areas. We'd especially love some help with plugin documentation.

• Some of our docs are generated.

  • Admin API
  • Configuration reference
  • CLI reference
  • Upgrade guide

All pull requests for these docs should be opened on the Kong/kong repository.

For Gateway Enterprise configuration reference and PDK reference documentation, open an issue on this repo and we'll update the docs.

• Community is a priority for us. Before submitting an issue or pull request, make sure to review our Contributing Guide.

• We are currently accepting plugin submissions to our plugin hub from trusted technical partners, on a limited basis. For more information, see the Kong Partners page.

Generate the PDK, Admin API, CLI, and Configuration documentation

---

This section is for Kong source code maintainers. You don't need to do anything here if you're contributing to this repo!

The PDK docs, Admin API docs, cli.md and configuration.md for each release are generated from the Kong source code.

To generate them, go to the Kong/kong repo and run:

scripts/autodoc <docs-folder> <kong-version>

For example:

cd /path/to/kong
scripts/autodoc ../docs.konghq.com 2.4.x

This example assumes that the Kong/docs.konghq.com repo is cloned into the same directory as the Kong/kong repo, and that you want to generate the docs for version 2.4.x. Adjust the paths and version as needed.

After everything is generated, review, open a branch with the changes, send a pull request, and review the changes.

You usually want to open a PR against a release/* branch. For example, in the example above the branch was release/2.4.

cd docs.konghq.com
git fetch --all
git checkout release/2.4
git checkout -b release/2.4-autodocos
git add -A .
git commit -m "docs(2.4.x) add autodocs"
git push

Then open a pull request against release/2.4.

Testing

Tests for this site are written using rspec and capybara with the apparition driver.

You'll need Google Chrome installed to run these tests.

To run the tests, you must first build the site by running make build before running make rspec.

Many of the tests are smoke tests to check issues that occurred whilst adding caching to the site, such as ensuring that the side navigation isn't cached.

To add your own tests, look in the spec directory and use home_spec.rb as a sample. You specify which URL to visit and then a CSS selector to search for, before asserting that the contents match what you expect.

it "has the 'Welcome to Kong' header" do
  visit "/"
  expect(find(".landing-page h1").text).to eq("Welcome to Kong Docs")
end

This test framework can also be used to test behavior added with JavaScript, but we do not have any examples at this time.

Continuous Integration

We run various quality checks at build time to ensure that the documentation is maintainable.

include-check

The include-check.sh script checks for any files in the app/_includes folder that depend on a page.* variable (e.g. page.url). This is not compatible with the include_cached gem that we use, and so using page.* in an include will fail the build.

To run the script locally, open a terminal and run ./include-check.sh whilst in the documentation folder. If there is no output, everything is successful

In the following example, we can see that deployment-options-k8s.md uses a page.* variable, and that the include is used in the kong-for-kubernetes.md file:

❯ ./include-check.sh
Page variables must not be used in includes.
Pass them in via include_cached instead

Files that currently use page.*:
File: app/_includes/md/2.5.x/deployment-options-k8s.md
via:
app/enterprise/2.5.x/deployment/installation/kong-for-kubernetes.md

Here are sample contents for those files:

In kong-for-kubernetes.md:

{% include_cached app/_includes/md/2.5.x/deployment-options-k8s.md }

In deployment-options-k8s:

This is an include that uses {{ page.url }}

To resolve this, the two files should be updated to pass in the URL when include_cached is called:

In kong-for-kubernetes.md:

{% include_cached app/_includes/md/2.5.x/deployment-options-k8s.md url=page.url }

In deployment-options-k8s:

This is an include that uses {{ include.url }}

The include_cached gem uses all passed parameters as the cache lookup key, and this ensures that all required permutations of an include file will be generated.
