In Juju, a configuration is a rule or a set of rules that define the behavior of your controller, model, or application.
Contents:
Controller configuration
Controller configuration affects the operation of the controller as a whole.
See more: List of controller configuration keys, How to configure a controller
Model configuration
Model configuration affects behavior of a model, including the controller model.
See more: List of model configuration keys, How to configure a model
Application configuration
Application configuration affects the behavior of an application.
Application configuration keys are generally application-specific. Depending on what the charm author has decided, they can be used to allow the charm user to make certain decisions about the application, for example, the server port on which the application should be available, the resource profile, the DNS name, etc.
See examples: Charmhub |
