Block Automatic Updates
Default Behavior
The a9s Service Broker allows the Platform Operator to allow or forbid the Application Developer to block automatic updates of their Service Instances.
By default the automatic updates property for the Service Instance is set to
false
. This results in all Service Instances being updated automatically when
the Platform Operator starts the update process for all Service Instances.
Forbidding Automatic Updates
Description
By enabling the Application Developer to block automatic updates, the Application Developers will be able to manually decide which of their Service Instance will get updated and which Service Instance will not.
However, when manually updating Service Instances with the CLI, Application Developers will have to add the
force_update
parameter to their command.
cf update-service MY_SERVICE -c '{ "force_update": true }'
The Application Developer will have to manually update their Service Instances when:
- A new BOSH release is installed
- A new stemcell is available
- If there is no new BOSH release or stemcell, it is not required to add the
force_update
parameter when manually updating your Service Instance. - The Platform Operator can also ignore the configuration by running the
force_deployment_updater
errand:bosh run-errand force_deployment_updater
. This command will update these Service Instances regardless if the Application Developer allowed the update or not. Theforce_deployment_updater
must be installed to be usable by the Platform Operator following the Installation chapter.
Installation
The Platform Operator can allow the Application Developer to block the automatic update by using
the ops/forbid-automatic-update-of-service-instance.yml
ops file.
The force_deployment_updater
is by default not part of the a9s Data Service deployment manifests. The Platform Operator
can apply the Ops file add-force-deployment-updater.yml
which can be found under the specific a9s Data
