Sequential Multiple Builds
You can loop through the RCB wizard to create any number of buildspecs. When you finish creating a buildspec, it is placed in a build queue. At that point, you have the choice of building the components (by running the buildspecs that are in the queue), or creating more buildspecs. buildspecs in the queue are processed consecutively.
You can reuse a buildspec, either as a starting point for creating a different specification, or by adding an existing buildspec to the build queue if you need to rebuild. For more information on build specifications, see Chapter 3, Buildspec Details.
