Jaeger website

This repo houses all the assets used to build the Jaeger website, available at https://jaegertracing.io.

The site is built with Hugo and hosted by Netlify.

Setup

Install the "extended" Hugo binary from hugo/releases (use one of the hugo_extended_* binaries) or use a package manager if it is available for your operating system.

The "extended" version of Hugo supports Sass, which is necessary to build the site locally.

The currently used version of Hugo is defined in the netlify.toml configuration file.

Running the site locally

If you want to develop the site locally, you can run a single command (assuming that you've run the setup):

$ make develop

This will start up a local server on localhost port 1313. When you make changes to either the content of the website (in content) or to the Sass and JavaScript assets of the page (in themes/jaeger-docs/assets), the browser will automatically update to reflect those changes (usually in under one second).

Publishing the site

The site is published automatically by Netlify whenever changes are merged to the main branch. The site cannot be published in an ad-hoc way (e.g. through a make command or script in the repo).

Contributing to the site

We strongly encourage you to contribute to this site! For more information, see the contributing guide.

Diagrams

Diagrams included in the documentation are created in the shared Google Slides document, which supports export to SVG. If you need to make changes to the diagrams as part of a PR, please copy the diagram into a new slide deck and include a shared link to it in the PR along with the exported SVG file. The maintainers will update the main deck with the new version upon merging the PR.

Publishing new Jaeger version

Please refer to RELEASE.md for instructions on how to release new version of documentation.

Admonitions

There are five admonition types available for the Jaeger docs:

Admonition type	Color
info	blue
success	green
danger	red
warning	yellow
requirement	purple

Here's an example:

{{< danger >}}
We do not recommend that you do this!
{{< /danger >}}

You can also add titles:

{{< success title="New feature" >}}
Jaeger now supports a new thing that you definitely want.
{{< /success >}}

Link checking

You can check internal links by running make check-internal-links and all links, including external links, by running make check-all-links.

Adding new pages and redirects

When new pages are added to the documentation, please add a corresponding entry to themes/jaeger-docs/layouts/index.redirects.

Generating Roadmap page

To generate the content/roadmap.md document, run the script

python3 scripts/generate_roadmap.py

This script fetches issues from the GitHub project board, extracts the required information, and generates the roadmap document. Make sure to set the GITHUB_TOKEN environment variable with your GitHub API token before running the script, or save the token in ~/.github_token file (protect the file so only you can read it: chmod 0600 <file>). Personal tokens can be created at https://github.com/settings/tokens/.
