This repository contains the documentation for Apache Iceberg. It's built with Hugo and hosted at https://iceberg.apache.org.
The Iceberg documentation site is actually constructed from two hugo sites. The first, is the landing page. The second site,
is the documentation site which contains the full Iceberg documentation, including the javadoc. The landing page and
documentation sites are completely self-contained in the ./landing-page
and ./docs
directories, respectively.
The Javadocs are in the ./javadoc
directory.
All markdown pages that are specific to an Iceberg version are maintained in the iceberg repository. All pages common across all version
releases are kept here in the iceberg-docs repo. A few exceptions are the markdown files that can be found in the format
folder in
the iceberg repository and contains markdown files that are copied into ./landing-page/content/common/
.
apache/iceberg
- The
docs
folder in the Iceberg repository contains all the markdown docs used by the versioned docs site. - The
format
folder contains some items that are common across all versions, such as the Iceberg format specification.
apache/iceberg-docs
- The
docs/content/docs
folder is the target folder when copying the docs over during a version release - The
landing-page/content/common
folder is where you can find the common markdown files shared across all versions
During each new release, the release manager will:
- Copy the contents under
format
in the iceberg repo to./landing-page/content/common/
in themain
branch - Create a branch in this repo from main named for the release version
- Copy the contents under
docs
in the iceberg repo to./docs/content/docs
in the release branch - Generate the javadocs for the release and copy them into the
javadoc
directory in the release branch - Update the latest branch HEAD to point to the release branch HEAD
Changes to the markdown contents for version specific pages should be submitted directly in the Iceberg repository.
Changes to the markdown contents for common pages should be submitted to this repository against the main
branch.
Changes to the website appearance (e.g. HTML, CSS changes) should be submitted to this repository against the main
branch.
Changes to the documentation of old Iceberg versions should be submitted to this repository against the specific version branch.
In summary, you can open a PR against where you find the related markdown file. With the exception of spec.md
, there are no duplicate
markdown files between the master
branch in the iceberg repo and the main
branch in the iceberg-docs repo. For changes to spec.md
,
PRs should be opened against the iceberg repo, not the iceberg-docs repo.
All issues related to the doc website should still be submitted to the Iceberg repository. The GitHub Issues feature of this repository is disabled.
Clone this repository to run the website locally:
git clone git@github.com:apache/iceberg-docs.git
cd iceberg-docs
To start the landing page site locally, run:
(cd landing-page && hugo serve)
To start the documentation site locally, run:
(cd docs && hugo serve)
If you would like to see how the latest website looks based on the documentation in the Iceberg repository, you can copy docs to this repository by:
rm -rf docs/content/docs
cp -r <path to iceberg repo>/docs docs/content/docs
cp -r <path to iceberg repo>/format/* landing-page/content/common/
If you'd like to scan for broken links, one available tool is linkcheck that can be found here.
Note: If you are a release manager looking to release a new version of the website as part of an Iceberg release, please refer to the Documentation Release section of the How to Release page.
The landing page site is automatically deployed to the root of the asf-site
branch by the deploy-landing-page
job in the deployment workflow. There is only a single version of the landing
page site, and the deploy-landing-page
job only runs on commits to the main
branch.
The docs site is automatically deployed to the docs
directory in the asf-site branch, into a sub-directory
named after the branch where the commit occurred. This is performed by the deploy-docs
job in the
deployment workflow. The job deploys the docs site on commits to any branch
except main
. A branch is maintained for each Iceberg version. If the job runs and the directory does not
yet exist in the asf-site
branch, it will be created.
Additionally, the contents of the javadoc
directory is deployed to a javadoc/<branch_name>
directory in
the asf-site
branch.
In ./docs/redirect/index.html, a redirect meta tag exists to forward /docs
and /latest
to /docs/latest
.
The asf-site
branch structure is the following:
.
├── docs
│ ├── 0.12.1
│ │ └── <Full Docs Site @0.12.1>
│ ├── latest
│ │ └── <Full Docs Site @latest>
│ └── index.html <-- Includes a redirect to 0.12.1 which is the latest version
├── javadoc
│ ├── 0.12.1
│ │ └── <Full javadoc site @0.12.1>
│ └── latest
│ └── <Full javadoc Site @latest>
└── <Full Landing Page Site>
A non-main
branch commit deploys the docs site into a new sub-directory in the
asf-site
branch's docs
directory, as well as copies the javadoc directory into a new sub-directory
in the asf-site
branch's javadoc
directory.
A main
branch commit deploys the landing page site only and overwrites the landing page site at
the root of the asf-site
branch.
Redirects within one of the two sites can easily be done using the aliases
keyword in the YAML Front Matter.
You can read more about this Hugo URL Management feature here.
For root level redirects that are outside of both sites, the ./redirects
directory contains pages with redirect meta
tags.
These are all deployed at the root level of the asf-site
branch by the Deploy redirects
step in the deployment workflow.
In some cases, it's useful to test both the landing-page site and the docs site locally. Especially in situations
where you need to test relative links between the two sites. This can be achieved by building both sites with custom
baseURL
and publishDir
values passed to the CLI. You can then run the site with any local live server, such as the
Live Server extension for VSCode.
First, change into the landing-page
directory and build the site. Use -b
and -d
to set baseURL
and publishDir
, respectively.
cd landing-page
hugo -b http://localhost:5500/ -d ../public
Next, change into the docs
directory and do the same thing. Remember that the docs-site is deployed to a docs/<VERSION>
url, relative to the landing-page site. Since the landing-page was deployed to ../publish
in the example
above, the example below uses ../public/docs/latest
to deploy a latest
version docs-site.
cd ../docs
hugo -b http://localhost:5500/docs/latest/ -d ../public/docs/latest
You should then have both sites deployed to the public
directory which you can launch using your live server.
Note: The examples above use port 5500
. Be sure to change the port number if your local live server uses a different port.
