KEDA - Docs

Documentation and landing page for the KEDA project at https://keda.sh.

Become a listed KEDA user!

Are you using KEDA in production? Do you want to become a listed user? Say no more!

You can easily get listed by following these steps:

  1. Upload your logo to static/img/logos/ (350x180)
  2. Configure your company as a new user in config.toml (sorted alphabetically)
[[params.users]]
url = "https://coralogix.com/"
logo = "coralogix.gif"

Here's a good example of Coralogix becoming a listed user!

Running the site locally

To run local site previews, you must install Hugo (the "extended" version with Hugo Pipes support) and Yarn.

Installing Hugo and Yarn on Linux

  1. Install Go, node and npm

  2. Install Yarn:

    npm install --global yarn

  3. Install Hugo:

    cd %HOME/src
git clone https://github.com/gohugoio/hugo.git
cd hugo
go install --tags extended

Installing Hugo and Yarn on Windows by using choco

  1. Install Hugo:

    choco install hugo-extended

  2. Install Yarn:

    choco install yarn

Installing Hugo and Yarn on Mac by using brew

  1. Install Hugo:

    brew install hugo

  2. Install Yarn:

    brew install yarn

Run the site locally

  1. Fork the keda-docs repository.

  2. Clone the fork.

  3. Navigate to your cloned repository and run the commands:

    yarn
    hugo server -D -F

    The Web Server is available at http://localhost:1313/.

Publishing the site

The KEDA website is published automatically by Netlify. Any time changes to this repo are pushed to master, the site is re-built and re-published in roughly two minutes.

Adding blog posts

To add a new post to the KEDA blog:

hugo new blog/my-new-post.md

This creates a boilerplate Markdown file in content/blog/my-new-post.md whose contents you can modify. The following fields are required:

  • title
  • date (in YYYY-MM-DD format)
  • author

Adding scaler documentation

To add documentation for a new KEDA scaler:

hugo new --kind scaler docs/<VERSION>/scalers/my-new-scaler.md

This creates a boilerplate Markdown file in content/docs/<VERSION>/scalers/my-new-scaler.md whose contents you can modify. Make sure to update the following metadata fields:

  • title
  • availability
  • maintainer
  • description

Writing documentation for a scaler

In order to maintain the style consistency across different scalers, all the parameters which are listed have to be written using this convention:

  • name - Description. (Values: x, y, z, Default: y, Optional, Extra Info)

If a parameter is required or doesn't have defined/default values, the missing info should be removed from the pattern.

Here are a few examples:

  • targetMetricValue - Target value for your metric.
  • metricFilter - Aggregation method of the metric. (Values: max, min, average, sum, variance, Default: average, Optional)
  • metricPeriod - Granularity of the metric. (Default: 300, Optional)
  • subscriptionName - Name of the Azure Service Bus queue to scale on. (Optional, Required when topicName is specified)

Add new Frequently Asked Question (FAQ)

To update the KEDA FAQ page, update the TOML file at [data/faq20.toml]. Here's an example question/answer pair:

[[qna]]
q = "How can I add a new question/answer pair?"
a = "You're looking at it! 😀"

Add new troubleshooting guidance

To add a new section to the troubleshooting page:

hugo new troubleshooting/<VERSION>/my-new-issue.md

To adjust the order in which the troubleshooting tiles appear, use the weight parameter in each page's metadata.

Working with documentation versions

The KEDA documentation is versioned. Each version has its own subdirectory under content/docs. To add a new version, copy the directory for the most recent version. Here's an example:

cp -rf content/docs/<CurrentVersion> content/docs/<NewVersion>

By default, new documentation versions are not listed as available version so it's safe to make changes to them. After every release, the version will be published as new version.

Publishing a new version

Once a version is ready to be published, we must add the version to the params.versions.docs list in config.toml.

More recent versions should be placed first in the list (ordering does matter because the first element in that list is considered the latest version).

Note: Remember to create the folder for next version with already existing docs in current version.
