App Platform is a Platform-as-a-Service (PaaS) offering that allows developers to publish code directly to DigitalOcean servers without worrying about the underlying infrastructure.
You can configure the amount of time that a component’s container has between receiving a termination command and actually shutting down. Container terminations occur when you redeploy or scale. Changing termination parameters can be useful if your app needs time to perform actions before shutting down, such as completing in-progress tasks, releasing resources, or saving data.
You can only change a component’s termination parameters by updating the app spec. To do this, add the following object to the component you want to configure in the app spec:
termination:
drain_seconds: 60
grace_period_seconds: 120
You can customize the values of the two parameters:
The drain_seconds parameter specifies the number of seconds to wait between selecting a container for termination and issuing the termination signal. Selecting a container instance for termination begins an asynchronous drain of new requests on upstream load balancers. The parameter’s default value is 15 seconds and the maximum value is 110 seconds.
The grace_period_seconds parameter specifies the number of seconds to wait after a termination signal (SIGTERM) is sent before the container is forcefully killed (SIGKILL). Your application can receive the termination signal and use this time to complete and save in-progress work. The parameter’s default value is 120 seconds and the maximum value is 600 seconds.
Once you have added the termination object to your spec, upload the spec to your app. This automatically triggers a deployment with the new termination parameters.
