fluxcd.io

This repo houses the assets used to build the Flux project's landing page at https://fluxcd.io.

Note: The sources for some of Flux's documentation are housed in other repositories within https://github.com/fluxcd. Documentation issues and pull requests should be made against those repos.

How to modify this website

The main landing page of this website can be modified in hugo.yaml.

Almost all of the content lives in the content/en/<project> directories. Here are some special cases.

./content/en/blog contains all blog posts - make sure you update the front-matter for posts to show up correctly.
./external-sources/ defines how files from other repositories are pulled in. We currently do this for Markdown files from the /fluxcd/community and /fluxcd/.github repositories. (make gen-content pulls these in.)
Flux CLI docs (cmd) and components docs: under ./content/en/flux but pulled in through in make gen-content as well.
/static/_redirects defines redirects on https://fluxcd.io. Check out https://docs.netlify.com/routing/redirects/ for the syntax definition and how to test if things work.

Running the site locally

In order to run the Flux site locally, you need to install:

Node.js
The Hugo static site generator. Make sure to install the "extended" variant of Hugo with support for the Hugo Pipes feature and to check the netlify.toml configuration file for which version of Hugo you should install.
jq

Once those tools are installed, fetch the assets necessary to run the site:

Then run the site in "server" mode:

make serve

Navigate to http://localhost:1313 to see the site running in your browser. As you make updates to the site, the browser will immediately update to reflect those changes.

Note: Sometimes you need to clear the output of previous builds, e.g. when the structure of imported documentation has changed. If you see duplicate pages being served, run
git clean -fx -- content/
and then run make serve again. The duplicates will then be gone.

Publishing the site

The Flux website is published automatically by Netlify when changes are pushed to the main branch. The site does not need to be published manually.

Preview builds

When you submit a pull request to this repository, Netlify builds a "deploy preview" of your changes. You can see that preview by clicking on the Details link of the netlify/fluxcd/deploy-preview check at the bottom of the pull request page.

Local Development (docker)

Run make docker-preview and wait until the following output appears:

Environment: "development"
Serving pages from memory
Web Server is available at //localhost:1313/ (bind address 0.0.0.0)
Press Ctrl+C to stop

Visit http://localhost:1313, where any changes will be visible from inside of the running container. Markdown files updated in content/ should trigger a browser refresh as they are saved.

The docker-preview target builds the theme, which takes a while and doesn't need to be repeated unless you are making changes to the theme. On subsequent runs, running make docker-serve instead will skip building the theme.

This depends on the Docker image fluxcd/website:hugo-support which should be kept updated when the website's build-time dependencies have changed; this image contains everything needed to run the docs locally.

If this doesn't work, the image may be stale. The instructions to update it are below.

Remote Development (kubernetes / okteto CLI)

This works the same as local development above, but with the Okteto CLI you do not need to run a Linux machine or virtual machine on your local development environment.

First, make sure you are permitted to deploy pods on any local or remote Kubernetes cluster. Download the Okteto CLI for Windows, Mac, or Linux.

Okteto CLI is a light-weight client-side tool that replaces Docker with a remote cluster. You can run hugo server remotely in this way; any changes to the local clone are synchronized to the cluster. The experience is basically the same as local development, (except that you won't need to install Docker.)

Instead of make docker-serve, type okteto up.

You can change the behavior in okteto.yml according to the Okteto Manifest Reference, for example adding a persistent volume can speed up the synchronization of the working directory files to the remote pod on repeated runs.

Updating the Development/preview container image

(For maintainers) Using a machine with docker and logged in with an account that has permission to push to docker.io/fluxcd/website repo, run make docker-push.

The dependencies of docker-push are explained below. If the above worked then you are done, and should not need to read any further. Rebuilding hugo takes a long time and should be avoided when the version hasn't changed or it isn't needed; run make docker-push-support instead to skip building hugo.

Update the docker-support image tag whenever build-time (or "serve"-time) dependencies have changed.

How is the Development container made?

These targets as explained below are run in the appropriate order as dependencies of make docker-push.

TODO: add a system/integration test for website that verifies any changes have not broken make docker-serve, for example by adding new dependencies without mentioning them in the ./Dockerfile.

Flux-specific Dependencies

The Flux website has some build-time dependencies including Python3, PyYAML, rsync, grep, nodejs, npm, curl, jq, (and potentially others that may be added in the future.) Flux-specific dependencies are prepared in an image that gets tagged as docker.io/fluxcd/website:hugo-support.

This image is built from the Dockerfile in ./; run make docker-build-support to rebuild it locally, (or run as make docker-push-support to build and also push.)

`gohugoio/hugo`

The Flux website also depends on a specific version of Hugo, which unfortunately does not provide docker images for each version. So we build it from source, with the HUGO_BUILD_TAGS=extended build arg enabled.

Run make docker-push-hugo to build and also push this image target.

This will run make hugo to get a shallow clone of the gohugoio/hugo repository at the right HUGO_VERSION and make docker-build-hugo to build a hugo container base image. (This target compiles golibsass which is very large, and may take a while.)

These are all the dependencies of make docker-push.
