juju set-constraints [options] <application> <constraint>=<value> ...
Sets machine constraints for an application.
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts
[<controller name>:]<model name>
Sets constraints for an application, which are used for all new machines provisioned for that application. They can be viewed with
juju get- constraints.
By default, the model is the current model.
Application constraints are combined with model constraints, set with
juju set-model-constraints, for commands (such as
juju deploy) that provision machines for applications. Where model and application constraints overlap, the application constraints take precedence.
Constraints for a specific model can be viewed with
juju get-model- constraints.
This command requires that the application to have at least one unit. To apply constraints to the first unit set them at the model level or pass them as an argument when deploying.
