Can be built locally from IDE by running AutoBuilder main method or with Maven by running:

mvn clean install

After the build is completed open target/web/index.html in your favourite web browser.

There's also an auto-builder utility that watches the filesystem and continuously rebuilds the website. This can be very useful when working on the website, especially making stylesheet changes, etc. This can be run from your IDE by running AutoBuilder, or from the command-line with:

mvn -Pauto-run exec:java

To serve the website locally with a web browser specify the base URL with KC_URL:

export KC_URL=http://localhost:8000
mvn install

Finally, when building the website to be published you need to include -Dpublish. This should usually not be done manually though as there is a GitHub Action that takes care of building and publishing to https://github.com/keycloak/keycloak.github.io.

Server and Operator guide sources are located at https://github.com/keycloak/keycloak/tree/main/docs/guides and are retrieved as a Maven dependency. By default the latest released version is used, but if you want to build the website with the latest guides from main first build the guides:

git clone https://github.com/keycloak/keycloak
cd keycloak
mvn -pl docs clean install

Then you can build the website with the 999.0.0-SNAPSHOT version:

cd keycloak-web
mvn clean install -Dversion.keycloak=999.0.0-SNAPSHOT
