Downtime Scheduler #
Downtime Scheduler automates the start and stop of an environment, so that the environment runs only when it is needed. You add a schedule to scale the environment up or down at a set time. BuildPiper creates and runs a default pipeline for each schedule: an up pipeline to start the environment and a down pipeline to stop it.
Stopping an environment means that BuildPiper reduces the pod count of all the services of that environment to zero, and starting it restores them. If the cluster is configured to scale automatically, it then scales down the unused nodes, which reduces the infrastructure cost.
The default pipeline scales the pods of the services. To also scale other related infrastructure, such as databases and middleware, edit the pipeline that BuildPiper created and add the steps that you need.
1. How It Works #
| Schedule type | Pipeline that runs | What it does |
|---|---|---|
| Scale Up | Up pipeline | Starts the environment at the scheduled time. |
| Scale Down | Down pipeline | Stops the environment at the scheduled time. |
You do not create these pipelines yourself. BuildPiper creates a default pipeline for each schedule of action and runs on the days, time and time zone you set. You can see them on the Pipeline Overview page, as described in the Schedule List section.

The up pipeline and the down pipeline of the environment are listed on the Pipeline Overview page, named after the environment, for example bp-dev_PR-CI-STATUS_up and bp-dev_PR-CI-STATUS_down.
