Environment Variables - Autopilot by Xano

The controller reads these environment variables (command-line flags take precedence).

Variable	Description	Default
`LOG_LEVEL`	Log level (`debug`, `info`, `warn`, `error`)	`info`
`DRY_RUN`	Set to `true` to enable dry-run	`false`
`METRICS_ENDPOINT`	Prometheus URL	`http://prometheus:9090`
`REBALANCE_INTERVAL`	Rebalance check interval	`5m`
`SCALE_COOLDOWN`	Cooldown between scale operations	`10m`
`GKE_PROJECT_ID` or `GKE_PROJECT`	GCP project ID	(none)
`GKE_LOCATION`	GKE cluster location	(none)
`GKE_CLUSTER_NAME` or `GKE_CLUSTER`	GKE cluster name	(none)
`NODE_POOL`	GKE node pool name	(none)

The autoscaler reads GKE_PROJECT, GKE_LOCATION, GKE_CLUSTER, and NODE_POOL from the environment as defaults for its corresponding flags.

Autopilot’s environment variables keep their GKE_* / OPS_AI_* prefixes — they are runtime configuration keys, not brand names, and existing deployments depend on them.
