PCF v2.4 Feature Highlights
Page last updated:
Warning: Pivotal Cloud Foundry (PCF) v2.4 is no longer supported because it has reached the End of General Support (EOGS) phase as defined by the Support Lifecycle Policy. To stay up to date with the latest software and security updates, upgrade to a supported version.
This topic highlights important new features included in Pivotal Cloud Foundry (PCF) v2.4.
Ops Manager v2.4 includes the following major features:
Ops Manager supports global cloud provider interface (CPI) extensions. You can customize your IaaS deployment using hundreds of different configuration extensions. This feature unlocks native IaaS features while retaining the inherent portability of PCF.
For more information about this feature, see Updating Director and IaaS Properties.
You can specify multiple BOSH releases for the BOSH Director deployed by Ops Manager. This feature allows you to deploy your own software, such as your specific antivirus programs, to BOSH-deployed VMs.
For more information about adding BOSH releases to a BOSH Director, see Deploying Software with BOSH.
PAS v2.4 includes the following major features:
restart commands simplify new app deployment.
You no longer need two application versions or client orchestration to achieve rolling app deployments.
For more information about rolling app deployments, see Rolling App Deployments (Beta).
You can create dynamic egress policies so your apps can communicate with external services. These policies are similar to Application Security Groups (ASGs) but include the following advantages:
- You do not have to restart your apps when applying these policies, so there is no downtime.
- You can apply them to specific apps.
For more information, see Administering Dynamic Egress Policies (Beta).
SMB volume services allow developers to bind existing SMB shares to their apps. The SMB protocol has native password authentication, which means you can control access to file shares without the overhead of configuring an LDAP server.
The Metric Registrar allows app developers to export custom app metrics and events in a format that Loggregator can consume. App developers can then use the custom metrics to monitor apps with PCF Metrics and configure autoscaling rules with PCF Autoscaler.
For more information, see the following topics:
As a nozzle developer, you can access the Loggregator v2 API through a Reverse Log Proxy (RLP) gateway. You do not need to manage mutual TLS to access the v2 API.
The Loggregator v2 API supports additional features, including selector-based subscription models. For more information about that feature, see Selector-Based Subscripton Model and Reference Nozzles in the PAS v2.2 release notes.
CredHub is enabled by default in the PAS tile. You can scale the number of CredHub instances in the Resource Config pane. In PAS v2.4, the number of CredHub instances defaults to 2.
For more information about CredHub, see the PAS v2.4 Release Notes .
In the PAS v2.4 tile, you can configure CredHub to use the same external database as other PAS components. The CredHub pane of the PAS tile has updated wording to make this setting clearer.
To use the same database for CredHub and other PAS components, whether the database is internal or external, select PAS database in the CredHub pane of the PAS tile. You configure the database later on the Databases pane.
To use a separate external database for CredHub only, select Other external database in the CredHub pane of the PAS tile.
For more information, see the PAS installation topic that corresponds to your IaaS:

PAS v2.4 uses the
cflinuxfs3 stack and its related buildpacks by default on new installations.
For more information, see the PAS v2.4 Release Notes.
PAS adds TLS encryption in the following areas:
- Internal MySQL system databases (beta)
- External MySQL databases by providing a CA certificate in PAS
- Communications between Gorouter and Linux cells
Additionally, authenticated containers that use mTLS support
cf ssh access.
The previous limitation has been removed.
PAS for Windows v2.4 includes the following major features:
You can now enable memory and disk overcommit for Diego cells. To configure this feature, use the Cell Memory Capacity (MB) and Cell Disk Capacity (MB) fields within the Advanced Features pane of the PAS for Windows (PASW) tile. For more information on this feature, see the Configure the Tile section of Installing and Configuring PAS for Windows.
Metrics emitted from PAS for Windows are now tagged with the BOSH deployment name of your PAS for Windows tile. 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. However, for upgrades to PAS for Windows v2.4, the feature is disabled by default.
For more information on this feature, see the PAS for Windows Release Notes.
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
For more information, see Step 2: Push App to PAS for Windows Cells in Migrating Apps to PAS for Windows.
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.
Apps Manager v2.4 includes the following major features:
Apps Manager has a global searchbar persistent on every Apps Manager page. With the global searchbar, you can search org name, space name, service instance name, and app names without leaving the page.
For more information about Apps Manager, see Using Apps Manager.
Apps Manager includes a restage button. The button is in addition to the stop and start buttons on the app management page. Restaging your application stops your app and restages it by compiling a new droplet and starting it.
For more information about the restage button in the Apps Manager UI, see Start, Stop, or Restage an App .
You can share service instances across the spaces you specify. With Space Developer permissions, you can view, add, and remove service instance sharing.
For more information, see Service Instance Sharing.
