Change a server's resources

PATCH

/servers/{serverId}

curl --request PATCH \
  --url https://example.com/api/v1/servers/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0 \

  --data '{ "resources": { "cpuMillis": 1, "memoryBytes": 1 }, "inNetwork": true }'

Needs servers.update, and the server must be READY (phase_busy otherwise). The new CPU and memory reservation must fit on the server’s Node, its current reservation excluded (insufficient_capacity). This makes a new generation; a running server restarts gracefully to apply it, since the JVM sizes its heap at start.

string format: uuid

Request Body^required

Media typeapplication/json

object

>= 1 properties

resources

A reservation, held even while the server is idle.

object

cpuMillis

required

CPU in thousandths of a core.

integer format: int64

>= 1

memoryBytes

required

inNetwork

Join or leave the network. A running server takes it at its next start (RESTART_PENDING until then); it leaves the lobby when it leaves the network.

boolean
