The KubeDirector Roles Screen

Clicking the Next button in the KubeDirector Services screen (see The KubeDirector Services Screen) opens the KubeDirector Roles screen, which is where you describe the pod roles that will be included in this application and assign services to those roles.



The What roles does your app contain? section of the screen allows you to:

CAUTION
APP WORKBENCH DOES NOT VALIDATE THIS INFORMATION. YOU MUST BE SURE THAT YOUR APPLICATION WILL SUPPORT ALL LISTED ROLES AS CONFIGURED ON THIS SCREEN AND THAT EACH ROLE WILL SUPPORT ALL SERVICE(S) ATTACHED TO THAT ROLE.

When you have finished defining the services for your application, click Next to proceed to the KubeDIrector Configuration screen. See The KubeDIrector Configuration Screen.

Adding a New Role

To add a new role:

  1. Enter the name of the role in the Role Name field. This will specify the name of the virtual node/container/pod.
  2. If desired, enter the minimum number of virtual CPU cores to use for this role in the CPU Size (Cores) field.
  3. If desired, enter the minimum amount of RAM in MB to use for this role in the RAM Size (MB) field.
  4. Enter the number of virtual nodes to be deployed for this role in the Cardinality field.
    • If you enter an integer, then a fixed number of virtual nodes. For example, entering 2 means that two virtual nodes of this role will be deployed.
    • If you enter an integer followed by a plus sign (+), then the integer specifies the minimum number of virtual nodes that will be deployed with this role. You may scale this out when deploying clusters/pods. For example, entering 2+ means that at least two virtual nodes of this role will be deployed; you may deploy a larger number if you choose.
  5. Expand the Services menu to display all of the services that you configured in the KubeDirector Roles screen. You may now:
    • Check a checkbox for a service to assign that service to this role.
    • Clear a checkbox for a service to unassign that service from this role.
  6. Click the Add button to add the new role.

You may now:

  • Role Name: Name of the role, which specifies the name of the virtual node/container/pod.
  • CPU Size (Cores): If specified, the minimum number of virtual CPU cores to use for this role.
  • Ram Size (MB): If specified, the minimum amount of RAM in MB to use for this role.
  • Cardinality: Number of virtual nodes to deploy for this role. This can be either an absolute number (if the cardinality is an integer) or a minimum (if the cardinality is an integer followed by a plus sign (+)).
  • Services: Any service(s) assigned to that role.
  • Edit: Clicking the Edit icon (pencil) for a service allows you to edit that role. See Editing an Existing Role.
