lynxpm scale

📖 Synopsis

lynxpm scale <name> <N> [--json]

Description

Brings the number of processes whose name matches <name> (including <name>-1, <name>-2, … siblings in the same namespace) to exactly N.

Scale up: clones the spec of the first existing member as a template; new instances get auto-assigned names <base>-<nextFreeIndex> and a fresh LYNX_INSTANCE env var.

Scale down: stops and deletes the highest-indexed members first so lower indices stay stable.

Requires at least one existing instance for scale-up (the template source). Target must be in [0, 1024].

⚙️ Flags

Flag	Type	Default	Description
--json	boolean	false	Emit the ScaleResponse as JSON on stdout ({before, after, created, deleted}).
-h, --help	-	-	Show help message.

🚀 Examples

lynxpm scale worker 5          # set 'worker' to exactly 5 instances
lynxpm scale prod:api 10       # namespace-qualified
lynxpm scale worker 0          # stop and delete all instances
lynxpm scale worker 5 --json | jq '.created, .deleted'

Notes

• Use namespace:name to target a specific namespace.
• Each scaled instance inherits the original’s restart policy, isolation mode, resource limits, and env-file.
• LYNX_INSTANCE is set to the instance’s ordinal (0-based from the original count).
