Stemcell Release Notes

This topic provides an overview of the Stemcell versions used by Pivotal Cloud Foundry (PCF).

Stemcells are available for download on Pivotal Network. Once downloaded, you can upload them to your deployment using the Stemcell configuration pane of a given tile or by navigating to the Stemcell Library page in Ops Manager v2.1 or later.

Before you upgrade PCF, always verify that any tiles that you have installed, either from Pivotal or a partner, are compatible with the version of PCF you are deploying and its supported stemcells. For more information on checking PCF and stemcell compatibility, see Tile Compatibility in the Upgrade Checklist.

To find out which stemcell version is used by which tile version, check the release notes or the Pivotal Network download page for the tile.

Note: A stemcell is a versioned OS image that BOSH uses to create VMs for the BOSH Director, Pivotal Application Service (PAS), and other PCF Service tiles, such as MySQL for PCF. For more information, see What is a Stemcell? in the BOSH documentation.

Ubuntu Linux Stemcell Lines

This section lists Linux-based stemcells used in Pivotal Cloud Foundry.

Trusty Stemcells

Each stemcell line has a corresponding release notes section. See the links below:

Trusty End-of-Support

Ubuntu 14.04 LTS (Trusty) stemcells are reaching end-of-support in April 2019. Starting in September 2018, Pivotal and its partners will begin releasing product tiles for PCF that support Ubuntu 16.04 LTS (Xenial) stemcells instead. Using supported stemcells is necessary to avoid exposure to security vulnerabilities.

Xenial Stemcells

Each stemcell line has a corresponding release notes section. See the links below:

Add-on Support for Xenial Stemcells

If you are using any of the following PCF add-ons, you must update the add-on and its configuration to be compatible with the Ubuntu Xenial 16.04 stemcell before deploying any tiles that use Xenial. The following add-on versions support the Xenial stemcell:

For information on which PCF tile releases now use Xenial, see Tiles Using Xenial Stemcells in PCF.
