CloudBees Accelerator 11.2 Now Available

Written by: Tim Johnson

Accelerator“That’s okay, my builds are fast enough.” - said no one ever.

Competitive pressures in all industries means our customers are always looking to squeeze more time out of the development cycles and are constantly scrutinizing their build and test stages. Time is money after all. For instance, for one of our financial services customers, waiting 15 minutes for a build to complete can mean millions of dollars in lost trades.

To help our customers keep up, with CloudBees Accelerator 11.2 we are introducing several new capabilities that dramatically shrink development cycles, improve software quality, and release more frequently. We’ve expanded its support as well as performance improvements for Jobcache, Android builds and embedded Linux/Yocto Project builds.

Read on for further details.

Accelerator is now available on the Google Marketplace

Accelerator can now be deployed on the Google Cloud Platform (GCP) Marketplace. GCP Marketplace lets you start up software packages easily without having to manually configure the software, virtual machine instances, storage, or network settings.

Performance Improvements

Jobcache has been extended to support caching of library creation steps on Linux. Jobcache now caches .so files from GNU ld or ld-compatible archivers and .a and .la files from jobs using GNU ar or ar-compatible archivers.

Amazon EC2 Spot instance support for cloud bursting

Customers using Amazon EC2 cloud bursting can now spin up spot instances on a resource basis to enable significant cost savings when their build runs out of static resources. They can also prefer spot instances over on-demand instances.

Extended Kubernetes support for cloud bursting

Customers who are moving to Kubernetes can now spin up Kubernetes resources on demand when their build runs out of static resources, leveraging Accelerator’s built-in fault tolerance. It is no longer required for eMake or the build initiator to be in the Kubernetes pod.

Android build improvements

Out of the box support for Android 10 (“Q”) builds is added. For Android first-time (“learning”) builds, eMake “kick starts” these builds by determining if you lack a history file and then providing a “kickstart” history file, which helps to reduce the build duration.

Improved support for Embedded Linux builds

The latest versions of the embedded Linux Yocto Project builds are now supported. This includes all Yocto versions from 2.0 (“Jethro”) to 3.0 (”Zeus”).

Usability Improvements

Users can now watch the progress of their builds. The percentage complete, number of agents running jobs, other statistics and error messages are now shown on the console. Output is controlled by the --emake-show-progress option.

Security Improvements

The Linux ClusterManager has been upgraded to use Apache 2.4.41, PHP 7.4.1 and OpenSSL 1.1.1d.

Additional platform support

CloudBees Accelerator now supports the following platforms:

  • RHEL 8.0 (64-bit)

  • RHEL 7.7 (64-bit)

  • RHEL 7.6 (64-bit)
