Configuring a deployment to be launched
This file contains the configuration parameters for starting a deployment. You can specify it in the [launch_configuration] field of a project configuration or pass it to spatial alpha local launch or spatial alpha cloud launch via the --launch_config flag.
Configuration file
The file may be called by any name but should have the following structure:
{
"template": "...",
"dimensionsInWorldUnits": {
"x": 100,
"z": 100
},
"loadBalancing": {
"layerConfigurations": [
{
"layer": "...",
"hexGrid": {
"numWorkers": ...
}
}
]
},
"snapshot": {
"takeSnapshotIntervalSeconds": "600",
"startDeploymentFromSnapshotFile": "snapshots/default.snapshot"
},
"streamingQueryInterval": 4,
"runtimeFlags": [
{
"name": "...",
"value": "..."
}
],
"workerFlags": [
{
"workerType": "...",
"flags": [
{
"name": "...",
"value": "..."
}
]
}
]
}
| Field | Required/Optional | Description |
|---|---|---|
template |
Required | Defines the compute resources your deployment needs (its ‘topology’). See game templates for more details. |
dimensionsInWorldUnits |
Required | Describes how big the world should be. “x” and “z” parameters must both be greater than 0. |
loadBalancing |
Optional | The new load balancing configuration as documented in load balancing with layers. |
snapshot |
Optional | Defines snapshot related settings. It contains two optional fields: - takeSnapshotIntervalSeconds: The frequency in seconds to automatically write snapshots of your simulated world. The minimum duration is 600 seconds (10 minutes). Set to 0 to disable automatic snapshots. Default value is 0. - startDeploymentFromSnapshotFile: A relative (to the location of this file) or absolute path to the default snapshot file to start deployments with. You can overwrite the snapshot to use with the --snapshot flag when starting a deployment with the spatial CLI. |
streamingQueryInterval |
Optional | Period in seconds between successive streaming query updates. The default value is 4 seconds. |
runtimeFlags |
Optional | The Runtime flags that can control advanced Runtime features. Equivalent to legacy flags. |
workerFlags |
Optional | Specifies global configuration parameters per worker type. See worker flags for more information. |
