# autoscale_engine configuration for dev environment.
# Baked into the Docker image at /autoscale_engine.yaml.
#
# Set dryRun: true in the output config to disable real control-plane actions.
#
# cloudProvider and clusterScalers are auto-discovered from the control plane
# ListSharedPools API at startup. No need to configure them here.
