Apache Karaf Website

This project contains the Apache Karaf website.

Contribute

The concrete repository is on the svn but if you want to contribute, you have to clone the Github repository which is a mirror and provide a pull request with your changes. You can find more informations about how to contribute on the community page of the project (https://karaf.apache.org/community.html).

Clone:

git clone https://github.com/apache/karaf-site.git

Building

Karaf website uses Jekyll to build (generate the HTML resources) and npm/sass to build the CSS assets (Bootstrap 5 based theme).

The Content-Security-Policy enforced on *.apache.org only allows script/style/font requests from 'self' and a short list of apache.org domains, so any asset loaded from a third-party CDN (jsdelivr, Google Fonts, etc.) is silently blocked by the browser. Bootstrap‘s JS and Font Awesome must stay self-hosted: Font Awesome is bundled into assets/css/karaf.css via _scss/karaf.scss (with its webfonts copied by npm run build:icons), and Bootstrap’s JS bundle is committed at assets/js/vendor/bootstrap.bundle.min.js — refresh it from node_modules/bootstrap/dist/js/bootstrap.bundle.min.js whenever the bootstrap npm version is bumped.

To install Jekyll, refer to https://jekyllrb.com/docs/

Install the node dependencies and the Ruby modules required by the site:

npm install
bundle install

Build the site for the first time, then start the local development server on http://localhost:4000 with auto-regeneration (this also recompiles the CSS):

npm start

To produce a one-shot static build (CSS + HTML) into _site/, without serving:

npm run build

Lower-level steps

npm start and npm run build both run the CSS build automatically. If you only need the individual steps:

npm run build:css   # compile the Bootstrap 5 theme (_scss/) to assets/css/karaf.css
npm run watch:css   # rebuild CSS continuously while styling
npm run build:icons # copy the Font Awesome webfonts to assets/webfonts
npm run optimize:svg # minify the SVG assets (logos) after editing any images/*.svg

assets/css/karaf.css and assets/webfonts/ are generated and gitignored — they are not committed. Once you have run npm start, npm run build, or npm run build:css/npm run build:icons at least once, they exist on disk and you can also run Jekyll directly:

bundle exec jekyll serve

You can also use Jekyll Docker image to server:

docker run --rm --volume="$PWD:/srv/jekyll:Z" --publish 4000:4000 jekyll/jekyll jekyll serve

This command builds website and start the local Jekyll server on http://localhost:4000

NB: your local Jekyll installation might need additional modules required by Apache Karaf website. Just run bundle install to install these modules.

Building with Docker

docker run --rm --volume="$PWD:/srv/jekyll:Z" -it jekyll/jekyll jekyll build

Deploy

Build the site for production (this also compiles the CSS and optimizes the SVGs, see note above):

JEKYLL_ENV=production npm run build

You can also use Jekyll Docker image to build (run npm run build:css and npm run build:icons first, since the Docker image cannot resolve the Bootstrap 5 Sass imports or copy the Font Awesome webfonts):

docker run --rm --volume="$PWD:/srv/jekyll:Z" jekyll/jekyll jekyll build

Package the war:

mvn clean install

You can test the war with Jetty embedded and visit http://localhost:8080/ :

mvn jetty:run

Deploy on scm

mvn install scm-publish:publish-scm
