CloudBees Accelerator 11.2® is now available


We are pleased to announce the general availability of CloudBees Accelerator 11.2. 

Cloudbees Accelerator 11.2 introduces several new capabilities that dramatically shrink development cycles and enable software engineering teams to improve software quality while releasing more frequently. The 11.2 release introduces multiple capabilities to support the use of Accelerator on public clouds including via listing on the GCP marketplace and with the addition of support for using AWS Spot instances (to minimize cloud spend while accelerating your CI-CD cycles). This release also introduces performance improvements via Jobcache, extends Kubernetes support and expands the support for Android builds and embedded Linux builds based on the Yocto Project.


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 using 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)
