Improve this Site

Thank you for improving this site! This site is open source and the API maintainers welcome your contributions. Please reach out if you have any questions. Minor changes may be made directly in GitHub’s online editor wherever   Edit  appears at bottom-right.

Changes are published automatically by GitHub pages when merged to branch “master”. When sending a pull request it’s necessary to change the base repo to “netfoundry/mop-api-docs” to avoid sending the request to the upstream forked theme repo.


The content of this site lives in the top-level directory /docs in the GitHub repo netfoundry/mop-api-docs. Most of the content is in /docs/_pages/ with meaningful names. You can add or edit Kramdown (GitHub-flavored Markdown) .md, .markdown; or Liquid template .html files.


The theme lives in the top-level / in the same GitHub repo as the content: netfoundry/mop-api-docs. The repo is forked from Minimal Mistakes v4.19.2 which publishes an excellent quick-start guide. The idea is to override theme defaults in the content area /docs in order to minimize changes to the upstream theme.

For example, /docs/_layouts/default.html overrides /_layouts/default.html and is available immediately in the local preview. Changes to the default, inherited theme files don’t become visible in the local preview until they’re merged to the master branch in the Git remote. Most changes should be overrides under /docs.


These steps provide a local preview server at http://localhost:4000/

  1. Install
    1. Git,
    2. Docker Engine, and
    3. Docker Compose
  2. clone the repo

     git clone
  3. switch to the content area /docs in the cloned working copy

     cd ./mop-api-docs/docs
  4. execute

     docker-compose up --build preview
  5. browse to http://localhost:4000/

  6. Be aware that search is not available in the local preview.
  7. Stop the preview container
    1. Focus the terminal where the container is running
    2. Send a SIGTERM, typically Ctrl-c
  8. Alternatively, you could
    1. run the preview container in the background

       docker-compose up --build --detach preview
    2. and later stop the preview container

       docker-compose down --remove-orphans

Things to Know

  • Local changes to files in /docs will be picked up immediately by Jekyll, except /docs/_config.yml which requires restarting the preview container.
  • Optionally, before running the container, export your GitHub API token as JEKYLL_GITHUB_TOKEN and it will be made available to Jekyll for querying metadata from the GitHub API.

GitHub Workflow

  1. fork the repo, unless you have access to main repo
  2. clone the repo
  3. make a change
  4. create a local branch
  5. commit your change
  6. push your commit to the remote
  7. create a pull request for your branch
  8. change the base repo to “netfoundry/mop-api-docs”
  9. submit your pull request
  10. monitor for build failures


  • All merges to the master branch are automatically published by GitHub pages.
  • Pushes to any branch trigger a Travis build. The Travis build
    • validates the changes with Jekyll, and
    • updates the Algolia search index. The Travis env var ALGOLIA_API_KEY is the secret key for updating the Algolia index that was configured in /docs/_config.yml.
  • The Travis job reports are sent to Slack in
    • The Slack token is encrypted with travis CLI in /.travis.yml by following steps prescribed in the Travis App for Slack
        # in /docs
        docker-compose run --rm build
        # iteractive in running container
        gem install travis --no-document
        travis encrypt "netfoundry:{redacted}" --add notifications.slack -r netfoundry/mop-api-docs

      The result of this is a new encrypted Slack token in the existing Travis config file /.travis.yml which you’ll need to commit and push to the Git remote to become part of your pull request.

  • The GitHub repo has a branch protection for master that requires a successful Travis build.
  • The domain name is a CNAME resource record in the hosted zone in Route53. The RDATA of the record is the GitHub Pages sub-domain.
