The master branch of this repository contains template files for creating the server sandbox image. There is a Jenkins job,
http://server.jenkins.couchbase.com/job/create-server-sandbox/ ,
which automates creating new git branches in this repository based on these templates. When these branches are created, a Docker Hub automated build is triggered to create the final Docker image.
If necessary you can push updates to the files in master (eg., to change automatic configuration, update ports, etc.). This will not cause any changes to existing branches or images, but will only affect later branches created by the Jenkins job.
Also note that this file (README-create.md) is removed on the branches to avoid confusion.
