StackHPC Kayobe configuration provides a set of mixin environments, which can be used to apply configuration in modular way. These provide a mechanism where users can opt into new sets of configuration mid-cycle, at a time of the their choosing, and thereby facilitate gradual adoption of new features. Config may be moved into the the base configuration for the next major release.
For more information about Kayobe environments, please see the upstream Kayobe documentation.
Note
To override settings in mixin environments, you will need to define the overrides in an environment that inherits from that one, rather than in the base configuration.
