First, start a local document server that automatically refreshes when you save files for
real-time preview. It relies on the
cilium/docs-builder Docker container.
Set up your development environment
To run Cilium’s documentation locally, you need to install docker engine and also the
To verify that
docker is installed, run the command
make --version and
docker --version in your terminal.
$ docker --version Docker version 20.10.22, build 3a2c30b $ make --version GNU Make 4.2.1
The preferred method is to upgrade to Windows 10 version 1903 Build 18362 or higher, you can upgrade to Windows Subsystem for Linux
WSL2 and run
make in Linux.
Verify you have access to the
makecommand in your
Download and install docker desktop.
Set up docker to use WSL2 as backend.
Start docker desktop.
Preview documentation locally
Navigate to the root of the folder where you cloned the project, then run the code below in your terminal:
$ make render-docs
This will build a docker image and start a docker container. Preview the documentation at http://localhost:9081/ as you make changes. After making changes to Cilium documentation you should check that you did not introduce any new warnings or errors, and also check that your changes look as you intended one last time before opening a pull request. To do this you can build the docs:
$ make test-docs
render-docs generates a preview with instructions to install
Cilium from the latest version on GitHub (i.e. from the HEAD of the main branch that has
not been released) regardless of which Cilium branch you are in. You can target a specific
branch by specifying
READTHEDOCS_VERSION environment variable:
READTHEDOCS_VERSION=v1.7 make render-docs
