Windows Diego Cells in Isolation Segments

This topic describes how to run Windows Diego Cells in isolation segments, which are compartmentalized resource pools for Diego Cells.

Diego Cells in one isolation segment share routing, computing, and logging resources with other Diego Cells in the same segment, and do not use resources from other isolation segments.

Overview

To run Windows Diego Cells in multiple isolation segments, you must create and install multiple Pivotal Application Service for Windows tiles and configure each to run in a different isolation segment.

To create multiple copies of the PASW tile, see Replicate a Tile.

To associate a PASW tile with an isolation segment, so that its Diego Cells run in that segment, see Assign a Tile to an Isolation Segment.

Prerequisites

To run a Windows Diego Cell in a particular isolation segment, the isolation segment must first already exist in the Cloud Controller Database (CCDB) before the Windows Diego Cell can be assigned to it.

To create an isolation segment in the CCDB, see the Create an Isolation Segment section of the Managing Isolation Segments topic.

Replicate a Tile

To make multiple copies of the PASW tile that you can assign to different isolation segments, you must use the Replicator tool.

To use the Replicator tool:

  1. Download the Replicator tool from the the Pivotal Application Service for Windows page on Pivotal Network.

  2. Navigate to the directory where you downloaded the Replicator tool.

  3. Replicate the tile by running:

    replicator-windows -name "TILE-NAME" -path PATH-TO-ORIGINAL -output PATH-TO-COPY
    

    Where:

    • TILE-NAME is a unique name for the new PASW tile. The name must be ten or fewer characters in length and contain only alphanumeric characters, dashes, underscores, and spaces.
    • PATH-TO-ORIGINAL is the absolute path to the original .pivotal PASW tile you downloaded from Pivotal Network.
    • PATH-TO-COPY is the absolute path for the copy of the .pivotal PASW tile that the Replicator tool produces.
      For example:
      C:\Users\admin> replicator-windows -name "Shiny Tile" ^
      -path c:\downloads\TileOriginal.pivotal ^
      -output c:\temp\TileCopy.pivotal
      
  4. Install and configure the Windows isolation segment, using the new .pivotal file and, following the procedures in Installing and Configuring PASW, starting with the Import a Product step of Install the Tile.

Assign a Tile to an Isolation Segment

To assign a PASW tile to an isolation segment:

  1. Select Application Containers.

  2. Under Segment Name, enter the name for the isolation segment to associate the tile with. If you are creating a new isolation segment, ensure that this name is unique across your Pivotal Cloud Foundry (PCF) deployment.

  3. Click Save.
