You can install and configure the VMware Tanzu Application Service for VMs [Windows] tile.

The TAS for VMs [Windows] tile installs Windows Diego Cells in your Operations Manager deployment.

The TAS for VMs [Windows] tile inherits settings from the VMware Tanzu Application Service for VMs (TAS for VMs) tile and also includes additional configuration settings.

To install, configure, and deploy TAS for VMs [Windows]:

Prerequisites

Before you install and configure the TAS for VMs [Windows] tile, you must meet the requirements for using the Windows FS Injector tool. For more information, see Windows FS Injector prerequisites.

Windows FS Injector prerequisites

Use the Windows FS Injector tool to install the TAS for VMs [Windows] tile. The Windows FS Injector tool requires:

  • The git and tar executable files must be in your %PATH%. If git and tar are not in your %PATH%, either add your git and tar to the locations in your existing %PATH% configuration, or copy the git.exe and tar.exe executable files to a directory in your %PATH%.

  • Your installation environment must allow the Windows FS Injector tool access to all of the following URLs:

    • https://support.broadcom.com/group/ecx/productdownloads?subfamily=VMware%20Tanzu%20Application%20Service%20for%20VMs%20%5BWindows%5D to download the Windows FS Injector
    • https://github.com/pivotal-cf/winfs-injector
    • https://s3.amazonaws.com/
    • https://registry.hub.docker.com/
    • https://production.cloudflare.docker.com
    • https://go.microsoft.com/
    • https://winlayers.cdn.mscr.io
    • https://mcr.microsoft.com
    • https://msecnd.net, or any domain within the Microsoft Windows Azure Content Delivery Network For more information about the Windows Azure Content Delivery Network, see the Microsoft documentation.

    To ensure the authenticity of Microsoft container images, Microsoft does not permit the distribution of its base images. This includes Microsoft container images consumed through Docker Hub, which are delivered by an Microsoft CDN endpoint.

Installing the TAS for VMs [Windows] tile

To install the TAS for VMs [Windows] tile:

  1. Go to VMware Tanzu Application Service for VMs [Windows] on Broadcom Support.

  2. Download the VMware Tanzu Application Service for VMs [Windows] product file.

  3. Download the Windows FS Injector tool for your workstation OS. The Injector tool, winfs-injector, is an executable binary that adds the Windows Server container base image into the product file. This step requires ISnternet access and can take up to 20 minutes.

    Caution You need the git and tar executable files in your %PATH% to run winfs-injector.exe. For example, copy git.exe and tar.exe to a directory in your %PATH%.

  4. Add the Windows Server container base image to the product file:

    winfs-injector ^
      --input-tile TASW-DOWNLOAD-PATH ^
      --output-tile TASW-IMPORTABLE-PATH
    

    Where: * TASW-DOWNLOAD-PATH is the path and filename to the TAS for VMs [Windows] product file you downloaded. * TASW-IMPORTABLE-PATH is the output path for the importable product file.
    For example:

    C:\Users\admin\> winfs-injector ^
    --input-tile c:\temp\pas-windows-2.9.0-build.1.pivotal ^
    --output-tile c:\temp\pas-windows-2.9.0-build.1-INJECTED.pivotal
    

    This step takes up to 20 minutes to complete.

    If you have the BOSH_ALL_PROXY environment variable set, this can cause the winfs-injector to fail, with an error similar to this:

    -- Failed downloading 'golang-1-windows/789a42163ee8b705cfcd8a62e590d5cbf01322c773497d6c53247cf6a4e39965' (sha1=sha256:55db4fe9804edfff5f01c5cee0d2541333a71f40c905135912c9c22783e038c1)
    

    If this happens, reset the BOSH_ALL_PROXY environment variable, and then try again.

  5. Go to the VMware Tanzu Operations Manager Installation Dashboard and click Import a Product.

  6. To add the TAS for VMs [Windows] tile to the Import a Product product list, select the importable TASW-IMPORTABLE-PATH file on your computer.

  7. To add the TAS for VMs [Windows] tile to your staging area, click + under the VMware Tanzu Application Service for VMs [Windows] product listing.

Configuring the TAS for VMs [Windows] tile

The following sections describe how to configure the settings for the TAS for VMs [Windows] tile.

Assigning availability zones and networks

In Assign AZ and Networks, you assign jobs to your Availability Zones (AZs) and networks.

To configure AZs and networks:

  1. Click the TAS for VMs [Windows] tile.

  2. Click Assign AZs and Networks or Assign Networks. The name of the pane varies depending on your IaaS.

  3. Select the first AZ under Place singleton jobs. Tanzu Operations Manager runs any job with a single instance in this AZ.

  4. Select all AZs under Balance other jobs. Tanzu Operations Manager balances instances of jobs with more than one instance across the AZs that you specify.

    Important For production deployments, VMware recommends at least three AZs for a highly available installation.

  5. From the Network drop-down menu, choose the runtime network that you created when you configured the BOSH Director tile.

  6. Click Save.

Configuring VMs

In VM Options, you configure settings for accessing your VMs.

To configure VM access:

  1. Click VM Options.

  2. In Administrator passwords, select one of the following:

    • To randomize the admin password, select Use randomized password. If you select this option, the admin password is not retrievable by an operator. This is the default selection.
    • To set the same admin password for every Windows Diego Cell, select Configure a password and enter a password in the Password check box. If you select this option, this is the password for all VMs that are used to access any Windows Diego Cell.
  3. (Optional) To start the Microsoft beta port of the OpenSSH daemon on port 22 for all VMs, select the Access VMs with BOSH SSH (beta) check box. If you select this option, it allows users to SSH into Windows VMs with the bosh ssh command and enter a CMD terminal as an admin user.

  4. (Optional) To configure a Key Management Service (KMS) that your volume-licensed Windows Diego Cell can register with:

    1. Under KMS, select Use.
    2. In Hostname, enter the host name for your KMS server.
    3. In Port, enter the port number of your KMS server. The default port number is 1688.
  5. Click Save.

Configuring smoke tests

In Smoke Tests, you specify the org and space where smoke tests are run.

In the org and space that you specify, the Smoke Test errand pushes an app to the org. The app runs basic function tests against your TAS for VMs [Windows] deployment after an installation or update.

The Smoke Test errand is turned on by default. You can turn off the Smoke Test errand in the Errands pane. For more information about settings for errands, see Configure errands.

For help configuring the smoke tests, see Configure smoke tests in Installing and configuring TAS for VMs [Windows] in the VMware documentation.

To configure smoke tests:

  1. Click Smoke Tests.

  2. If you have a shared apps domain, select A temporary space within the system org. This creates a temporary space in the system org for running smoke tests and deletes the space afterwards. Otherwise, select Smoke test location and specify the domain, org, and space. To configure where TAS for VMs [Windows] pushes an app to run smoke tests:

    • In Org, enter the org TAS for VMs [Windows] you can use when pushing an app to run smoke tests.
    • In Space, enter the space TAS for VMs [Windows] you can use when pushing an app to run smoke tests.
    • In Apps Domain, enter the domain TAS for VMs [Windows] you can use when pushing an app to run smoke tests.

Configuring Advanced Features

The Advanced Features screen includes new capability that might have certain constraints. Although these features are fully supported, VMware recommends caution when using them in production environments.

For help filling in these text boxes, see Configure Advanced Features in Installing and Configuring TAS for VMs [Windows] in the VMware documentation.

The following sections describe how to configure the Advanced Features.

Diego Cell memory and disk overcommit

Use the overcommit settings if your apps do not use the full allocation of disk space and memory set in Resource Config. These settings control the amount to overcommit disk and memory resources to each host VM.

For example, you can use the overcommit if your apps use a small amount of disk and memory capacity compared to the amounts set in the Resource Config settings for Windows Diego Cell.

Because of the risk of app failure and the deployment specific nature of disk and memory use, VMware has no recommendation for how much, if any, memory or disk space to overcommit.

To enable overcommit:

  1. Click Advanced Features.

  2. In the Diego Cell memory capacity text box, enter the value in MB for the total amount of memory to allocate to each Diego Cell. See the Diego Cell row in Resource Config for the current Diego Cell memory capacity settings that this setting overrides.

  3. In the Diego Cell disk capacity text box, enter the value in MB, for the total amount of disk to allocate to each Diego Cell. See the Diego Cell row in Resource Config for the current Diego Cell disk capacity settings that this setting overrides.

  4. Click Save. Entries made to each of these text boxes set the total amount of resources allocated, not the overage.

Gorouter app identity verification (beta)

You can choose the method the Gorouter uses to verify app identity. Verifying app identity using TLS or mutual TLS (mTLS) activates encryption between the Gorouter and application containers, and guards against misrouting during control plane failures. This feature is deactivated by default.

For more information about Gorouter route consistency modes, see Preventing misrouting in HTTP Routing.

To configure app identity verification:

  1. Select Advanced Features.

  2. Under Gorouter app identity verification (beta), select one of the following options:

    • The Gorouter uses TLS to verify app identity: Activates the Gorouter to verify app identity using TLS. This is the default option.
    • The Gorouter and apps use mutual TLS to verify each other’s identity
    • Disallow app identity verification and mutual TLS: Deactivates app identity verification and mutual TLS. Activates the Gorouter and your apps to verify each other’s identity using TLS. Before you turn on this option, consider:
    • This option deactivates TCP routing because application containers accept incoming communication only from the Gorouter.
    • If you activate mTLS in the TAS for VMs [Windows] tile, you must also activate mTLS in the App Containers pane of the TAS for VMs tile.
    • You need v2.3 or later of both TAS for VMs and Isolation Segment. The Gorouter and Diego Cell components in Pivotal Cloud Foundry v2.2 and earlier do not support mTLS handshakes.
  3. Click Save.

Custom Windows Diego Cell overlay subnet

The IP range for the overlay network of your Windows Diego Cell. The default range is 172.30.0.0/22.

IP address space for container networking. If this conflicts with any internal IP addresses that your organization uses, you can customize this subnet. Unlike in TAS for VMs [Windows] deployments using Linux Diego Cells, you configure this subnet per Diego Cell. When you configure a custom subnet for a Windows Diego Cell, ensure that:

  • The CIDR range of your custom subnet does not conflict with any resources that your apps might need to use.

  • The subnet is large enough to accommodate the number of apps you expect to have running on each Diego Cell.

To configure a custom Windows Diego Cell overlay subnet:

  1. In the TAS for VMs [Windows] tile, click Advanced Features.

  2. For Diego Cell overlay subnet, enter the subnet you want to configure for your Diego Cell.

    Caution Setting the subnet too small limits the number of containers that can run on each Windows Diego Cell.

  3. Click Save.

Configuring errands

Errands are scripts that Tanzu Operations Manager runs when it installs or uninstalls a product. For example, a new version of TAS for VMs [Windows]. There are two types of errands: post-deploy errands run after the product is installed, and pre-delete errands run before the product in uninstalled.

By default, Tanzu Operations Manager runs all errands.

In Errands, you can change these run rules. For each errand, click On to run it each time Tanzu Operations Manager installs or uninstalls a product, or Off to never run it.

For more information about how Tanzu Operations Manager manages errands, see Managing errands in Tanzu Operations Manager.

To configure errands:

  1. Click Errands.

  2. To receive the most up-to-date HWC buildpack, set the Install HWC Buildpack Errand to On.

  3. To ensure that a smoke test is run against your TAS for VMs [Windows] installation, set the Smoke Test Errand to On.

  4. Click Save.

This beta feature verifies only that the client certificate is signed by the expected CA using mTLS. It does not include SAN (Subject Alternative Name) verification of the presented client certificates.

Configuring isolation segments (optional)

To deploy your TAS for VMs [Windows] app workloads to an isolation segment, click App Containers and follow the procedure in Assign a tile to an isolation segment in Windows Diego Cells in isolation segments.

Configure Windows authentication (optional)

To configure Windows Diego Cells to allow application containers to perform Windows authentication, click Windows Authentication and follow the procedure in Configuring the tile for Windows authentication in Windows authentication for .Net apps.

Use an isolation segment for Windows Authentication, so that all apps in the TAS for VMs [Windows] installation have access to the GMSA credentials.

Configuring system logging (optional)

Click System Logging:

  1. (Optional) To configure Windows Diego Cells to send VM logs to an external syslog server, follow the procedure in Forwarding logs to a syslog server in Troubleshooting Windows Diego Cells.

  2. (Optional) For OpenTelemetry Collector Metric Exporters (beta), the default value is empty, which disables the beta OpenTelemetry Aggregate Metric Egress support. To configure TAS for VMs [Windows] to send metrics over the OpenTelemetry protocol, enter valid OpenTelemetry Collector Exporter YAML configuration in this field. See Configuring the OpenTelemetry Collector for examples of how to configure exporters. Currently TAS for VMs [Windows] provides support for a limited number of OpenTelemetry Collector Exporters, including the OTLP exporter. This feature is in beta and may still change in significant ways.

Caution If you configure a metric exporter that listens on a port, ensure that the port is not claimed by a TAS for VMs [Windows] component on any of the VMs in your deployment.

Note Windows stemcells in the v2019.x line support ephemeral disks.

Configuring DNS search domains (optional)

To configure DNS search domains for your application containers:

  1. Click the VMware Tanzu Application Service for VMs tile in the Installation dashboard.
  2. Click Networking to open the Networking pane.
  3. In the DNS search domains text box, enter DNS search domains as a comma-separated list.
  4. Click Save.

Configuring tile resources

In Resource Config, you must associate load balancers with the VMs in your deployment to enable traffic.

To configure your tile resources:

  1. Click Resource Config.

  2. Use the drop-down menus to configure the Windows Diego Cell. The table shows the recommended Windows Diego Cell disk size for your IaaS:

    IaaS Recommended Windows Diego Cell Disk Size
    AWS 100 GB
    Azure 150 GB
    GCP 150 GB
    vSphere 100 GB

    Note Windows stemcells in the v2019.x line support ephemeral disks.

  3. Provision your Master Compilation Job with at least 100 GB of disk space.

  4. Click Save.

Uploading the stemcell

After you configure resources for the TAS for VMs [Windows] tile, you must upload the Windows stemcell to the tile.

To upload the stemcell:

  1. In the TAS for VMs [Windows] tile, click Stemcell Library.

  2. Retrieve the stemcell that you downloaded or created in Downloading or creating a Windows stemcell.

  3. Follow the procedure in Importing and managing stemcells to upload the Windows stemcell to TAS for VMs [Windows].

Important If you use vSphere, you must create your own stemcell. The default root disk size of Windows stemcells v2019.x line is 30 GB.
VMware recommends setting the root disk size of your Windows stemcell for vSphere to 30 GB. For more information, see Creating a Windows stemcell for vSphere using stembuild.

Preparing a Windows rootfs image in a private registry

To create a TAS for VMs [Windows] tile, a windows file system container image is typically fetched from a Docker registry. An administrator can fetch the windows file system image from either cloudfoundry/windows2016fs the publicly hosted Docker Hub repository, or a privately hosted container image registry.

To prepare a windows file system container image in a private registry:

  1. Create an accessible Windows Server 2019 machine in your environment.
  2. Install Docker on this Windows Server 2019 machine.
  3. Configure this Windows machine’s Docker daemon to allow non-redistributable artifacts to be pushed to your private registry. For information about configuring your Docker daemon, see the Docker documentation.
  4. Open a command line on the Windows machine.
  5. To download the windows file system container image, run:

    docker pull cloudfoundry/windows2016fs:2019
    
  6. To tag the Windows container image, run:

    docker tag cloudfoundry/windows2016fs:2019  REGISTRY-ROOT/cloudfoundry/windows2016fs:2019
    

    Where REGISTRY-ROOT is your private registry’s URI.

  7. To upload the Windows Container image to your accessible private registry, run:

    docker push IMAGE-URI
    

    Where IMAGE-URI is the URI to the Windows rootfs image in your private registry. Your image URI follows the pattern:

    my.private.registry/cloudfoundry/windows2016fs:2019.

Add the Windows Server container base image to the product file

To add the Windows Server container base image to the product file in an air-gapped environment, run:

winfs-injector ^
  --input-tile TASW-DOWNLOAD-PATH ^
  --output-tile TASW-IMPORTABLE-PATH ^
  --registry TASW-REGISTRY-URI

Where:

  • TASW-DOWNLOAD-PATH is the path and filename to the TASW product file you downloaded.
  • TASW-IMPORTABLE-PATH is the output path for the importable product file.
  • TASW-REGISTRY-URI is the uri to the container image registry hosting your cloudfoundry/windows2016fs image.

For example:

C:\Users\admin> winfs-injector ^
--input-tile c:\temp\pas-windows-2.6.0-build.1.pivotal ^
--output-tile c:\temp\pas-windows-2.6.0-build.1-INJECTED.pivotal ^
--registry https://my.registry.com
