Pick any open and unassigned issue in the list of GitHub issues and assign it to yourself by leaving a comment here in the issue. Then update the example by following these steps:

• [ ] Fork the examples repo on GitHub.
• [ ] On a new branch, make a copy of latest example directory (mostly 1.10 or 1.9) for your package and name it 1.11.
• [ ] Test the example on a DC/OS 1.11 cluster. As you test, replace the old screenshots with new ones and make any necessary corrections to the example.
• [ ] Feel free to also improve the instructions.
• [ ] Add a link to your newly created 1.11 example to the README.md file for your package's directory.
• [ ] Report your results:
  • If the example works out of the box, or you are able to correct it, open a PR with your changes (including the example itself and its addition to the README.md file) and add it to the issue.
  • If you can’t get your example to work, add a detailed description of what went wrong on the issue (you still get stickers!).

When you’re done, email [email protected] with the following information: Subject: 1.11 Example Testing - [Service Name] Body:

• Your name
• GitHub Issue link
• Your Twitter handle, if you have one
• Community Slack handle if you have one
• Mailing address (for the stickers)

The Community team shepherd will review your PR and either work with you to make modifications or just merge it if it looks good.

It would be nice to see this one updated to be a simple GitLab only pipeline, instead of pulling in Jenkins as well.

I am currently working on this example, as well as simplifying it to no longer require Registry as well as Jenkins, and therefore breaking new ground trying to work out how to run the GitLab Runner as a DC/OS service.
