Pivotal Cloud Foundry 2.3, Powered by Industrialized Open Source, Helps You Deliver Superior Business Outcomes. We Recap the Latest Release

September 25, 2018 Jared Ruckle

 Since its inception, Pivotal Cloud Foundry® (PCF) has joined industrialized open source software with superior business outcomes. That’s once again the case with Pivotal Cloud Foundry 2.3, now generally available.

What’s industrialized open source? We start by actively contributing to the most useful open source projects. Then, we package up this tech, and make it consumable by enterprises like yours, by:

  1. Testing security updates and new releases to make the bits enterprise-ready. (We respond to vulnerabilities quickly too.)

  2. Providing tooling that helps you rapidly perform security updates and platform upgrades.

  3. Refining and packaging new open source projects as they mature.

  4. Simplifying the adoption of new distributed computing patterns.

  5. Building a thriving ecosystem, with structured ways to engage with partners.

PCF 2.3 does this with all the usual projects like Cloud Foundry, Kubernetes, Spring, and Steeltoe. We do this for the embedded OS that powers PCF, as well (both Linux and Windows).

Why do we do all this? That’s where the business outcomes come into play.

What do we mean by business outcomes? You should talk to a Pivotal customer! But the next best thing is to recap the 5 Ss:

  • Speed. Your goals are shorter cycle times and more frequent deployments.

  • Stability. What’s the uptime of your customer-facing apps? Can your internal teams count on a reliable “dial tone” of platform services for their software?

  • Scale. You want to be comfortable with the resiliency of your apps, even as traffic surges.

  • Security. You want your patch level to be 100%.

  • Savings. You’re being asked to build and run more software than ever before. Are you spending money on the projects that matter?

Keep industrialized open source and business outcomes in mind as you read through the updates.

PKS 1.2: Kubernetes 1.11, support for AWS, and multi-master capabilities across AZs

Ask any IT leader what they want from Kubernetes and they will likely tell you they want it “to work as expected.” Yup. That’s why we say the killer feature for Kubernetes is operability. You need the system to work properly before you can do anything of business value. Operability has been the focus for Pivotal Container Service® (PKS) since its launch earlier this year.

That is true for PKS 1.2 as well. The new version is jam-packed with oodles of great features that simplify how you run Kubernetes at scale in production.

The top enhancements:

  • AWS Support. Want to run PKS on AWS? Starting with PKS 1.2, you can. Choose the right IaaS for you: AWS, GCP, or vSphere.

  • Kubernetes 1.11. Did you know Kubernetes ships new releases every 3 months? It’s true. And Pivotal helps you keep pace with this fast-moving project. That’s why PKS 1.2 will include Kubernetes 1.11, the latest, GA’d version of Kubernetes at this time. (And yes, PKS 1.2 has been certified by CNCF for Kubernetes conformance.)

  • Resilience and High Availability. PKS 1.2 will add multi-master capabilities across availability zones. This boosts stability in case of a disaster.

  • Enterprise Security. PKS 1.2 will enable Kubernetes-native role-based access controls (via kubectl) through enterprise directories such as LDAP. This is a follow-on feature that expands how the PKS control plane works with LDAP. Separately, PKS 1.2 will include several important security enhancements related to credential management.

Check out the in-depth PKS 1.2 blog for all the details. Also, our friends at VMware have their own blog post up with their take. [UPDATE: PKS 1.2 is now live!]

Share data from your backing services responsibly with Service Instance Sharing, now GA

This feature, previously a beta, graduates to GA in PCF 2.3. The name says it all—Service Instance Sharing—it helps development teams get access to the backing service instances used by others. When engineers get quick access to the data stores they need, it’s easier for them to go faster.

But you can’t share data at random. That’s why Service Instance Sharing supports the isolation of responsibilities and respects the roles of each team member. This diagram explains how it works:

Several tiles now support this feature—like MySQL for PCF, RabbitMQ® for PCF, Redis for PCF, and Spring Cloud Services for PCF. And you can expect to see more with this capability over time.

Curious about the CLI experience? Here’s a demo walkthrough of Service Instance Sharing with RabbitMQ for PCF.

Service Instance Sharing in PCF. Note: the commands have changed slightly since this recording.

Use CredHub to manage credentials for your on-demand service instances and your shared service instances

What keeps InfoSec pros up at night? You can bet leaked credentials are on the shortlist. A while back, CredHub launched to mitigate the risk from this perpetual bugaboo. Over time, it has become a larger and larger part of the Cloud Foundry project.

Here’s how CredHub improves your security posture in PCF 2.3.

Use CredHub with on-demand service instances

The on-demand services SDK was recently updated to support CredHub. Now, tile authors that use this SDK can easily make CredHub the repository for all service instance secrets!

Service Instance Sharing <3 the CredHub Service Broker

Service Instance Sharing gets even better with the new CredHub Service Broker.

With the CredHub Service Broker and Service Instance Sharing, platform owners can reduce the complexity of managing external service credentials throughout the platform. Better still, this dynamic duo is designed to ensure that platform credentials aren't exposed to unauthorized users.

We’ll have a tutorial blog post with more details on this use case in the coming days! In the meantime, enjoy this fun sketch of CredHub! [UPDATE: Here's the tutorial.]

Pivotal updates the Embedded Operating System—Linux and Windows—so you don’t have to

Still wasting time with operating system patches and upgrades? Pivotal customers never do. Case in point: in PCF 2.3, several core components now embed Ubuntu 16.04. Platform engineers will roll this update out—along with the rest of PCF 2.3—at the click of a button, with zero downtime.

Here’s the list of tiles now powered by this OS:

  • PCF Operations Manager 2.3

  • Pivotal Application Service 2.3

  • PCF Event Alerts 1.2.3

  • Metrics Forwarder for PCF 1.11.3

  • MySQL for PCF 2.4

  • Scheduler for PCF 1.2.3

  • Spring Cloud Services for PCF 2.0.2

  • Spring Cloud Data Flow for PCF 1.2.0

  • Single Sign-On (SSO) for PCF 1.7.1

Other tiles will be updated in future releases. Want to know more about this enhancement? Check the release notes.

PAS for Windows includes Windows Server v1803

We automate patches and upgrades on the Windows side of the house, too. Where, by the way, the pain of managing the OS is almost certainly more acute. Why? Well, the tooling for the Windows Server ecosystem is a few years behind the Linux world. (But the gap is closing.) And Microsoft has dramatically accelerated the Windows Server release cycle. Instead of a 10-year support term, you’re looking at 18 months! You need to find a way to go faster if you want some semblance of operational hygiene.

Savvy Windows Server admins already have an answer: “Pivotal does this for me.” To wit: PAS for Windows ships with Windows Server v1803, the latest version. The new Windows release reduces the memory footprint for apps, thanks to a smaller container image. Security is better, because PAS for Windows leverages network ACLs provided in v1803 to control network traffic.

No matter how often Microsoft pushes out updates, you can bump the Windows Servers in your PCF deployment instantly. And with Windows Server 2019 right around the corner, why would you do it any other way?

PAS for Windows: use multi-buildpacks to push apps and their dependencies

Speaking of Windows...there’s more to PAS for Windows 2.3 than just a new OS version. The tile now supports multi-buildpacks for .NET apps. Here’s what we wrote about this feature when we launched it for PAS:

Thanks to multi-buildpack support in PCF 1.12, you don’t need to rely on DIY buildpacks (or docker packaging) as much. The familiar, supported buildpack flow now applies in more scenarios. This helps you go faster.

Go ahead and use the tried-and-true buildpack model in more scenarios. For starters, .NET developers can more easily consume app dependencies, like database drivers, Microsoft-provided frameworks, and partner integrations. You’re likely to find this useful with a bevy of monitoring, metrics, and logging tools in the Pivotal Services Marketplace.

Move to cloud-native .NET with Steeltoe 2.1

What comes to mind when you think of cloud-native patterns? Microservices? Sure. 12-factor apps? Definitely. Service discovery, and circuit breakers? Yes and yes.

Pivotal launched the Steeltoe® project to make these patterns easy and accessible for .NET developers. Fast forward two years, and it’s amazing to see how far the project has come!

Steeltoe 2.1 is a massive release that gives .NET devs incredible convenience when it comes to running .NET Framework apps on PCF.

Management and Monitoring (M&Ms)

Microservices are the architecture of choice for high-velocity development teams. (Just know that everything doesn’t have to be a microservice.) One trade-off? Monitoring and diagnosing production issues can be challenging. Steeltoe 2.1 adds an excellent set of features to help you in this regard.


Think Steeltoe is just for .NET Core apps? Not anymore. Dave Tillman explains:

When we started the Steeltoe project (over two years ago!) we decided to focus solely on supporting .NET Core and ASP.NET Core. We discovered pretty quickly that was not a great choice. Many organizations were simply trying to do a “lift-and-shift” of their ASP.NET 4.x apps to Cloud Foundry. What they really needed were tools to help make that easier.

Steeltoe 2.0 enabled the Config Server, Eureka Server, and Connectors to be used with a 4.x application. This version tacks on security and management capabilities, specifically for single sign-on (via SSO) and identity management (UAA).

.NET Core & ASP.NET Core 2.1

Of course your ASP.NET 4.x apps can benefit from running on a modern platform like PCF. But .NET Core and ASP.NET Core is the future. Dave Tillman writes:

Finally, with this release, in addition to supporting .NET Core 2.0, ASP.NET Core 2.0, and .NET 4.6.1+, we are also adding support for .NET Core 2.1 and ASP.NET Core 2.1. We preserve compatibility with .NET Core/ASP.NET core 2.0. So, if you drop the Steeltoe 2.1 release into a .NET/ASP.NET Core 2.0 app, you should see only a few  “Microsoft.Extensions” packages (e.g., Logging, Options, Configuration) that will update to 2.1. Your ASP.NET Core dependencies should not be impacted.

And be on the lookout for the recordings of these excellent SpringOne Platform .NET talks. They will be posted in the coming days!

Spring Cloud Services for PCF turns 2.0, adds support for Spring Boot 2

Not to be outdone by the pace of the Steeltoe team, our Spring engineers released Spring Cloud Services 2.0 for PCF. Ben Klein's blog post covers the highlights well:

Spring Cloud Services 2.0 is built atop the latest major releases from the open source Spring Boot and Spring Cloud projects. That’s right: along with the service broker, all of the server-side components provided by Spring Cloud Services—Config Server, Service Registry, and Circuit Breaker Dashboard—are now based on Spring Boot 2.0 and Spring Cloud Finchley. That means that each Spring Cloud Services component will work seamlessly with client applications written in or upgraded to Spring Boot 2.0.

And if you’re not on Spring Boot 2 yet, we’ve got you covered with backward compatibility.

Spring Cloud Data Flow for PCF 1.2 adds integration with Scheduler for PCF, plus the latest open-source SCDF Features   

As you’d expect, Spring Cloud Data Flow for PCF 1.2 packages up all the goodness from the open source SCDF 1.6. There’s a ton to like:

  • Dashboard improvements

  • Kubernetes support enhancements

  • App hosting tool

  • Composed Task Runner security

  • DSL and deployment property parsing refinements

  • Batch database schema and optimization

The tile also features some slick integration with Scheduler for PCF. Our own Sabby Anandan explains why PCF users will love this feature:

Though we notice and acknowledge the shift from batch to streaming architectures, we also continue to learn new requirements for batch processing. It is not going away anytime soon.

For instance, to address the scheduling requirements for batch use cases, Spring Cloud Scheduler and Spring Cloud Scheduler for Cloud Foundry have joined the Spring Cloud Data Flow ecosystem. The first iteration of this begins with the native PCF Scheduler integration in SCDF’s Cloud Foundry implementation.

The definition of a task/batch pipeline and the launching of the pipeline are two essential steps, and now there’s a new addition to the workflow —a pipeline can now be scheduled with a cron-expression. The PCF Scheduler interacts with the staged task droplet in Cloud Foundry and it launches the task when the cron-evaluated outcome matches the current time.

Check out this screencast, and get some ideas on how you can automate task scheduling in your workflows!

Additional security for data in transit: Mutual TLS App Identity Verification

It’s not really a PCF update unless we’ve got a TLS enhancement, right? We’ve been hard at work adding this encryption tech throughout the platform. In PAS 2.3, operators can make sure that only the Gorouters can communicate with app containers. These components use mutual TLS to verify each other’s identity. This option increases security over one-way TLS, because it ensures that the Gorouter is the only client that can communicate with app instances. In fact, this feature prevents other anonymous clients on the IaaS network from even sending requests to apps.

The mTLS app identity verification isn’t currently compatible with TCP routing or CF SSH. But you should definitely enable this for the HTTP/S workloads you have on PCF!

PCF Healthwatch includes Alerting History and a new, extensible UI

The reception of PCF Healthwatch—an “out of the box” monitoring for your platform—has been overwhelmingly positive. We’ve partnered with customers to implement their feedback to make the product even better. These interactions are reflected in two nifty enhancements, Alerting History and a new Alert Stream dashboard. With PCF Healthwatch 1.4 and Event Alerts installed, you are alerted when there might be a problem. You don’t have to fixate on your tools unless you have to! From there, our curated monitoring will help drive you to a resolution fast.

Alerting History

When your system isn’t working as expected, you need all hands on deck to help diagnose and fix the issue. The new Alerting History Details feature is your go-to starting point in this scenario. All your practitioners with access to Healthwatch see the same data and will literally be on the same page. No more wasted time tracking down your fellow engineers for context. It’s all right there.

Extensible UI

The PCF Healthwatch UI gets a makeover! The UI is more extensible, so you can better understand the state of your platform across a variety of sources.

PCF Healthwatch features a new, extensible UI.

One other important update: PCF Healthwatch 1.4, per usual, is automatically updated to reflect the latest PCF KPI/KSI changes. (PCF Healthwatch can help you move to SRE monitoring principles. Read how internal Pivotal teams have modernized their practices.)

PCF Metrics 1.5 adds Streaming Metrics to help you watch for anomalies post-deployment

If platform engineers use PCF Healthwatch to look after the platform, what can developers use to look after their apps? PCF Metrics of course! (We’ve written about plenty of times before.) PCF Metrics is tailored to help devs quickly root-cause issues in the era of microservices.

New in PCF Metrics 1.5: a snazzy streaming metrics feature. Turn it on, and your metrics charts are updated in real-time as data is ingested. Neat, huh? Use this feature when you want to closely examine your systems, like after a deployment. Is everything going as expected? Is there any weird behavior going on? PCF Metrics will tell you!

PCF Metrics 1.5: Note the new “play” button in the upper right next to the timeline. This enables real-time streaming of your metrics data.

Also updated in this release: the log data is now stored in PostgreSQL; the Metrics MySQL datastore is now Percona.

Power users of Ops Manager rejoice: disable verifiers by type with the API

Operations Manager includes handy verification checks to give you quick feedback when you bump up against incompatibilities and version conflicts. These act as useful guardrails if you’re new to PCF. But they can sometimes get in the way of power users who have unique configurations. Now, experienced platform engineers can override verification checks in Ops Manager.

For example, your deployment may have a unique configuration that the verifier cannot detect. In this case, you can unblock your deployment by disabling the verifier. So if you don’t want to waste time slogging through potential issues, this API-only feature is for you. Please note: we recommend you work with Pivotal Support when using this feature. This is the best way to ensure your platform stays healthy!

Polyglot Service Discovery now supports a custom internal domain

Here’s a handy addition. We announced polyglot service discovery in the last PCF release. In PCF 2.3, you can use a custom internal domain with your apps, instead of the default apps.internal domain. Simply modify this value in Application Developer Controls pane of the PAS tile.

Other Enhancements

Apps Manager gets greater parity with the cf CLI

Developers new to PAS can use Apps Manager to become proficient with common platform functions. In PAS 2.3, Apps Manager gains additional parity with the CLI for restaging, named service bindings, and more.

Pivotal Cloud Foundry 2.2 and higher are now OpenID Connect certified

Hurray for standards! The UAA and SSO Service modules are now OpenID Connect certified. (Check out the OIDC list.) Alignment with this industry standard gives assurances that identity and access management in PCF will interoperate with other compliant tools.

Multiple Data Centers on OpenStack

Building redundancy at the AZ level for on-prem deployments is now much easier. Why? Because Ops Manager now allows you to configure multiple OpenStack data centers to a single BOSH Director. (You may recall, we launched this feature for vSphere in PCF 2.2.) NOTE: This feature is not recommended for use with regions, where data centers are physically hundreds of miles apart.

PSA: Start to plan your migration to the new cflinuxfs3-based buildpacks

Pivotal now maintains cflinuxfs3 stack, based on Ubuntu 18.04, and associated buildpacks. So now is a good time to start planning your migration to this updated stack. Work with your platform architect to create a migration plan to cflinuxfs3 from the current cflinuxfs2 stack. This should be a smooth process for the vast majority of your applications.
