Release Notes

The cf-release v241 was released on August 29, 2016.

IMPORTANT - UPDATE 2016-09-02 17:06 UTC - MySQL implicitly ends transactions before (and often after) certain statement including DDL statements. A Cloud Controller database migration in CF-241 is encrypting the specified buildpack of an application as this column could contain a Git url containing a username and password. To perform this migration, it creates new columns, encrypts the existing buildpack data and saves it to the new columns, then deletes the old column. This results in a period of time where Cloud Controllers running the code from a previous release can potentially write data to the old column, which is about to be deleted, when an app is pushed with a specified buildpack. While these sort of migrations are uncommon, this is not the first time Cloud Controller has made this sort of migration. Operators that are particularly sensitive to this can always scale their Cloud Controller to a single instance in order to take downtime while the migration is performed. The CAPI team intends to explore how we can make migrations on MySQL better in the future. - UPDATE 2016-09-01 21:36 UTC - The underlying Sequel gem automatically runs migrations in a transaction for RDBMs that support transactions for DDL statements. This means PostgreSQL will run the entire migration in a transaction, but MySQL will not. We are still determining the proper steps to take for MySQL. - UPDATE 2016-09-01 17:25 UTC - The Cloud Controller database migration in CF-241 is not wrapped in a transaction. During a rolling deploy of Cloud Controllers, API requests to Cloud Controllers with the previous code could result in data inconsistencies. We will update these release notes when we determine the proper resolution. - CVE-2016-6638: The Cloud Controller in CF-241 contains a database migration to encrypt an app’s specified buildpack at rest. Although it is not recommended, a user could specify a git buildpack url containing a username and password. This migration will cause /v2/apps API (or any API call that returns app resource data through inline-relations-depth or summary endpoints) to fail during the rolling deploy as the migration is performed before the updated Cloud Controller(s) are deployed. - This release updates the version of PostgreSQL used in the postgres job to 9.4.9 from 9.4.6. This also drops support for being able to upgrade from PostgreSQL 9.4.2. Before upgrading to this or later versions of cf-release, you must first upgrade to v226 or higher. - This release introduces official support for running the etcd cluster (shared by several components such as Routing API and the loggregator subsystem, but not Diego which uses its own secure cluster) in secure TLS mode. Upgrading an existing deployment with an insecure etcd cluster to a secure one with minimal downtime is non-trivial. Instructions and additional information for this procedure can be found here. If you are using the manifest generation scripts included within the cf-release repo to generate manifests, you’re strongly recommended to upgrade to a secure etcd cluster at this point. The instructions above assume you are upgrading to a secure etcd cluster from a pre-v241 Cloud Foundry deployment and will not apply as smoothly if you later attempt to upgrade a post-v241 non-TLS etcd cluster to a TLS cluster within the Cloud Foundry deployment.
