Node

The Node module deploys and undeploys a group of modules to form an application. It is the bootstrap module and is not itself deployed from the modules array.

Configuration

The module reads modules and optional deployment settings from its configuration. The deployment order defaults to first, system, authn, default, last.

Properties

Name	Description	Default	Mandatory
modules	Modules to deploy. Each module defines its own name, enabled state, group and configuration.	[]
groups	Legacy/top-level deployment group order. The server.deployment.groups setting takes precedence when present.	["first", "system", "authn", "default", "last"]
server.deployment.groups	Deployment group order.	Value of groups, otherwise ["first", "system", "authn", "default", "last"]
server.deployment.group_affiliations	Map of module names to their default deployment groups. Configured entries override built-in affiliations.	Built-in platform affiliations
heartbeat	Optional HTTP heartbeat configuration. The heartbeat module starts after configured modules have started.	{"enabled": false}

Example

{
  "server.deployment.groups": ["first", "system", "default", "last"],
  "server.deployment.group_affiliations": {
    "HttpClient": "system",
    "MyModule": "default"
  },
  "modules": [
    {
      "name": "HttpClient",
      "enabled": true,
      "instances": 2,
      "worker": false,
      "config": {}
    },
    {
      "name": "MyModule",
      "enabled": true,
      "group": "default",
      "instances": 1,
      "worker": true,
      "config": {}
    }
  ],
  "heartbeat": {
    "enabled": false
  }
}

Module

Each entry in modules supports the following properties:

Name	Description	Default	Mandatory
name	Module class name or alias.
enabled	Whether the module is deployed.	true
group	Deployment group. When omitted, the configured or built-in module affiliation is used, then default.	"default" or module affiliation
instances	Number of instances to deploy.	1
worker	Whether to deploy the module using worker execution.	false
config	JSON object passed to the module.	{}

Heartbeat

The optional heartbeat object enables the HTTP heartbeat after all configured modules have started. See Heartbeat for the responder settings and defaults.
