Permission for Scaling

Note

The role permissions may not update instantly. Changes may take 2-5 minutes to sync and apply.
For Azure:
- If the Resource Group of the Virtual Network is other than Kyvos, you must add custom roles with the required permissions, as mentioned below in the (Scaling Permissions) table. If Virtual Network is in the same Resource Group as Kyvos, no additional permission is required for scaling nodes as Azure Managed Identity has Contributor access rights to all resources of the given Resource Group.
- While creating a custom role, add the Resource IDs for the following services in the assignable scope:
  - Application Gateway
  - Virtual Network
  - Network Security Group
- Once the custom role is created, it must be assigned to each of the above-listed services.
