rune scale

rune scale <service-name> <replicas> [flags]

Examples

rune scale my-service 3
rune scale my-service 5 --namespace=production
rune scale my-service 10 --mode=gradual --step=2 --interval=1m
rune scale my-service 0 --no-wait

Flags

Flag	Default	Notes
-n, --namespace	from context	Service namespace.
--mode	immediate	immediate or gradual.
--step	1	Gradual mode — instances per step.
--interval	30s	Gradual mode — time between steps.
--rollback-on-fail	true	Revert to prior scale if health checks fail.
--wait	true	Block until rollout completes.
--no-wait	false	Override --wait. CI-friendly.
--timeout	5m	Rollout timeout.
--api-server	from context	One-off API server override.

Behavior

• Setting <replicas> to 0 stops the service without deleting it. Same as rune stop.
• Gradual scale aborts on health failure and rolls back (unless you disabled rollback).
• The scale operation is idempotent — re-running with the same target is a no-op.
