If you want to render and publish your multilingual book or website with CI, you must render your project with render_book() or render_website(), respectively. Don’t use Quarto’s own render and publish steps. You can find more information about publishing with CI in the Quarto documentation.
When you render a project in a CI context, you can set the URL of the publishing website in an environment variable (if different from the one in the _quarto.yml configuration file, as a preview for instance). You can do that with the BABELQUARTO_CI_URL environment variable.
For instance, for GitHub Actions, the workflow would contain these lines:
env:
BABELQUARTO_CI_URL: <the-url>To render your project with CI, you need to follow these general steps:
render_book() or render_website() functions_site or _book folder) where you deploy your project (a GitHub pages branch, Netlify, etc.)Your Quarto multilingual website or book is a static website. To publish it, you need to deploy the output folder, i.e. _site or _book. That content can be served on any service, for instance GitHub Pages or Netlify.
You cannot rely on usual tooling by Quarto because that would only publish the main language.
You need to publish the entire output folder, including the language folders. Example workflow using GitHub Pages by committing the output folder to a gh-pages branch.
Here are a few examples of how you could render a multilingual book with CI using GitHub Actions:
