Released: <Hudi Version>

Abstract

...

To address these gaps, restructuring of the docs is needed to make the process easier.   Migration with Travis-ci, it can build the asf-site branch and execute callback scripts.

The diagram below shows the structuring and the workflow.

Versioning docs

The release-specific documentation should evolve with the code changes.  Thus, maintaining the docs regarding design, implementation details and API examples on master under /docs would make things easier.  In this way, the code and the corresponding docs change can coexist in the same PR.  Specific pages around these include:

• Quickstart
• Concepts
• Writing Data
• Querying Data
• Configuration
• Performance
• Administering

In addition to these docs, a new set of API docs will be generated by javadoc for each release (similar to this).

Content regarding the general information of Hudi should remain in asf-site branch:

• Use Cases
• Talks & Powered By
• Comparison
• Releases
• Community
• Code
• Developers
• Feedback

The release-specific docs on master and general content in asf-site are generated separately.  The generated web pages are then uploaded to the hosting server for the Hudi site.  The landing page references the specific version of docs content through links.

For backward compatibility, we can manually generate the content for current (0.5.0-incubating) and one or two old releases (0.4.6/0.4.7), to fit into the new docs structure. 

Automating docs update

To make updating and deploying docs content easier, a set of scripts automating the above process will be added.  In this way, once the changes to the /docs on either master or asf-site are landed, the update content pages can be uploaded to the hosting server of Hudi website.  The API docs on master branch is also going to be maintained in this way.

Rollout/Adoption Plan

• No impact on existing users regarding APIs as this is docs website change.

Test Plan

• Test the content organization locally to make sure the links are working and the content is readable

Key Points

There are several key points need to consider:

• How to migration with travis-ci
• How to use git command safely in travis-ci (important)

To use git command safely, hidden the password, we need use bellow form.

git clone https://${GIT_TOKEN}@github.com/${GIT_REPO}/${GIT_PROJECT}.git

Steps to get the {GIT_TOKEN}

Steps - 01 : Enable two-factor authentication

Steps to migration with travis-ci

Steps - 01 : Active repository

Steps - 02 : Add {GIT_TOKEN} to environment variables

Steps - 03 : Add .travis.yml file to asf-site branch

language: ruby
rvm:
  - 2.6.3

git:
  clone: false

env:
  global:
    - GIT_USER="CI BOT"
    - GIT_EMAIL="cibot@test.com"
    - GIT_REPO="apache"
    - GIT_PROJECT="incubator-hudi"
    - GIT_BRANCH="asf-site"
    - DOCS_ROOT="`pwd`/${GIT_PROJECT}/docs"

before_install:
  - git config --global user.name ${GIT_USER}
  - git config --global user.email ${GIT_EMAIL}
  - git clone https://${GIT_TOKEN}@github.com/${GIT_REPO}/${GIT_PROJECT}.git
  - cd ${GIT_PROJECT} && git checkout ${GIT_BRANCH}
  - gem install bundler:2.0.2

script:
  - pushd ${DOCS_ROOT}
  - bundle install
  - bundle update --bundler
  - bundle exec jekyll build _config.yml --source . --destination _site
  - popd

after_success:
  - \cp -rf ${DOCS_ROOT}/_site/* test-content
  - git add -A
  - git commit -am "Travis CI build asf-site"
  - git push origin asf-site --force

branches:
  only:
    - asf-site

Steps - 04 : Check whether ci works well or not

End

Hope, this will works well

Test

had test https://github.com/lamber-ken/lamber-ken.github.io, when commits, it will generate docs and push the content to asf-site branch.
