V3: Multiple droplets for one app?
|
Kopecz, Klaus <klaus.kopecz@...>
Hi
I'm looking at the V3 controller API specification. It seems that an app can have multiple droplets assigned. In the app creation sample response, there is a "droplets" entry in the "links" section. While I see that it is possible to set a "current" droplet, how to assign multiple droplets to an app and what are the constraints and use cases for this (blue/green?). The same multiplicity shines through when it comes to creating tasks. There, a 'droplet_guid' can be assigned (defaults to the "current" droplet). Can I assign any droplet here, or is the choice somehow limited to droplets assigned to the app for which I'm creating the task? Thanks Dr. Klaus Kopecz SAP SE |

Hi,

Droplets are the result of [1] staging a package, they are only assigned to an application when staging a package belonging to the same application. You can assign a single droplet from the apps list of droplets as current. The current droplet will be used for all processes and will be the default for tasks, although tasks can specify a droplet from the list of the app’s droplet instead of using the current droplet. Hope that helps, let us know if we can clarify further, Nick [1] http://v3-apidocs.cloudfoundry.org/version/3.3.0/index.html#create-a-droplet -- Nicholas Calugar Product Manager - Cloud Foundry API Pivotal Software, Inc.
