New Features in PAS for Windows v2.4

PAS for Windows v2.4 includes the following major features:

Smoke Tests are Available

Smoke Tests are available in PAS for Windows v2.4 to verify cf push and app routability at deploy time. The Smoke Test Errand, disabled by default, can be enabled and configured within the PAS for Windows Tile. You have the option of choosing a temporary or specified organization and space for smoke tests.

Note: Before enabling Smoke Tests in an environment lacking internet access, please review Known Issues.

For more information on Smoke Tests, see Step 3: Configure the Tile in Installing and Configuring PAS for Windows.

Developers Can Push with Default Windows Stack

Developers can push apps using cf push -s windows. Pushing apps with this command ensures that you are pushing with the Windows stack with the latest rootfs.

For more information, see Step 2: Push App to PAS for Windows Cells in Migrating Apps to PAS for Windows.

SMB Support for Windows Containers

SMB mounting allows developers to bind existing SMB shares to their containerized apps. Previously, SMB shares were only accessible by using the SharpCIFS library. PASW v2.4.0 natively supports SMB mounting.

SMB Mounting is enabled by default when you upgrade to PASW v2.4.0.

SMB Mounting can be utilized with or without Steeltoe. Enabling SMB mounting without Steeltoe requires running the net use command.

For more information, see Using SMB Volumes in .NET Apps.

New Advanced Features in PAS for Windows v2.4

The Advanced Features pane of the PAS for Windows tile includes new functionality that may have certain constraints.

Although these features are fully supported, Pivotal recommends caution when using them in production.

Memory and Disk Overcommit for Diego Cells

You can now enable memory and disk overcommit for Diego cells. If you want to configure this feature, use the Cell Memory Capacity (MB) and Cell Disk Capacity (MB) fields on the Advanced Features pane of the PAS for Windows tile.

Note: Due to the risk of app failure and the deployment-specific nature of disk and memory use, Pivotal has no recommendation about how much, if any, memory or disk space to overcommit.

For more information, see the Configure the Tile section of Installing and Configuring PAS for Windows.

Uniquely Identify Metrics from PAS for Windows

Metrics emitted from PAS for Windows are now tagged with the BOSH deployment name of your PAS for Windows tile. For example, pas-windows-GUID. With a GUID, you can uniquely identify your metrics by tile. In PAS for Windows v2.3 and earlier, metrics use the cf tag as the deployment name.

This feature is enabled by default in new deployments of PAS for Windows v2.4. For upgrades to PAS for Windows v2.4, the feature is disabled by default. You can configure this setting in the Advanced Features pane of the PAS for Windows tile:

• If the Use “cf” as deployment name in emitted metrics instead of unique name checkbox is disabled, PAS for Windows metrics are tagged with the BOSH deployment name of your PAS for Windows tile.
• If the Use “cf” as deployment name in emitted metrics instead of unique name checkbox is enabled, PAS for Windows metrics are tagged with cf as the deployment name.

Note: Enable the cf value only if it is required for backward compatibility with previous versions of PCF or if you have scripts that rely on metrics with cf as the value for deployment. Pivotal does not recommend enabling the cf value as a permanent solution.

Pre-Installed Visual C++ Redistributables

PAS for Windows v2.4.11 and later includes Microsoft Visual C++ Redistributables for Visual Studio 2010, 2015, 2017 and 2019. This change is backported to PAS for Windows v2.2 and later.

This update improves the developer experience by making Visual C++ Redistributables readily available for .NET apps. Developers no longer have to manually bin deploy to reference C++ or C++ based libraries.

Known Issues

PASW Smoke Test Errand timeout in environments lacking internet access

The PASW Smoke Test Errand may fail when running cf login due to certificate validation timeout. Certificate validation timeout is known to occur if an environment lacks internet access and its load balancer certificates are configured to validate over the internet. For more information, see PASW Smoke Test Errand will timeout and fail when attempting to run ‘cf login’ in the Pivotal Support knowledge base.

No Mutual TLS App Identity Verification

PAS for Windows v2.4 does not support mutual TLS app identity verification. Mutual TLS app identity verification does not work for Windows containers.
