Shared Roles


We recommend using Shared Roles for POC or Development environments, not Production. The best practice for Production is to maintain in-house images to ensure it follows your security standards.

Syncing shared roles lets you use pre-built Images that are provided by Scalr for use on Public Clouds including AWS, Azure, and GCE. To access them, you must execute the following command:

scalr-server-manage sync-shared-roles
