minInstanceCount and maxInstanceCount in metainfo is used to define the absolute range of the no of running instances for a specific component of your application. It depends a lot on your application logic. For e.g. If your app has a master and there cannot be more than 1 running master at a given point in time, then you would set maxInstanceCount of master to 1. If you have a worker and your app needs at least 3 workers without which it cannot perform anything meaningful then you would set minInstanceCount of worker to 3.
The no of instances you specify in resources.json is the no of instances you want the first time the app starts. Slider validates that no is within the min-max range as specified in metainfo. Subsequently whenever you do flex of a component the total no of instances are validated against min-max as well. Hope this helps. -Gour On 3/13/17, 7:35 PM, "David.Serafini" <david.seraf...@target.com> wrote: >I'm confused by the documentation for instance counts. >resources.json specifes the number of instances of a component, but >metainfo specifies min and max. >How do these two configurations interact?
