Update a Deployment KEDA config with the APC API

The examples on this page show common ways to use the APC API — they’re not a complete API reference. For the full, interactive API documentation for your installation, including every available query, mutation, and type, go to https://houston.<your-base-domain>/v1, and click on the Docs tab. See Develop and test APC API queries for more on using the built-in GraphQL explorer.

Kubernetes Event-driven Autoscaling (KEDA) scales Celery workers based on task queue depth. Enable KEDA for a Deployment using the updateDeploymentKedaConfig mutation:

1 mutation {
2   updateDeploymentKedaConfig(
3     deploymentUuid: "<deployment-uuid>"
4     state: true
5   ) {
6     id
7     label
8   }
9 }
