If you’d like to check this out, here’s the PR containing the pipeline and job scripts: https://github.com/apache/geode/pull/1006
And the pipeline itself: https://concourse.apachegeode-ci.info There are three pipelines defined: - develop: runs `gradle build`. Can be extended to include other precheckin tests based on feedback. - docker-images: builds the container used for the develop pipeline. - meta: watches for changes to the pipeline files and automatically updates the runtime pipelines. Authentication is integrated with GitHub. If you want the ability to manually stop/start jobs please request on the dev@g.a.o mailing list (same as for Jenkins) and include your GitHub id. What do you think?
