TiDB Operator 1.1 Beta.1 Release Notes

Release date: January 8, 2020

TiDB Operator version: 1.1.0-beta.1

Action Required

• ACTION REQUIRED: Add the timezone support for all charts (#1122, @weekface).

  For the tidb-cluster chart, we already have the timezone option (UTC by default). If the user does not change it to a different value (for example: Aisa/Shanghai), all Pods will not be recreated.

  If the user changes it to another value (for example: Aisa/Shanghai), all the related Pods (add a TZ env) will be recreated (rolling update).

  Regarding other charts, we don't have a timezone option in their values.yaml. We add the timezone option in this PR. No matter whether the user uses the old values.yaml or the new values.yaml, all the related Pods (add a TZ env) will not be recreated (rolling update).

  The related Pods include pump, drainer, discovery, monitor, scheduled backup, tidb-initializer, and tikv-importer.

  All images' time zone maintained by tidb-operator is UTC. If you use your own images, you need to make sure that the time zone inside your images is UTC.
