Tasks

A task is a configuration from which services can be started.

Configuration

The configuration path for each task is local/tasks/NAME.json
After changing a configuration, you need to execute tasks reload in the console.

Tip

We recommend managing the configurations with the tasks command. In that case you do not need to keep an eye on the json syntax, and you do not need to reload the configurations after changing anything.

name

This defines the name used along with the incremental id to identify services started from this task (e.g. Proxy will result in Proxy-1)

runtime

This sets the runtime used for services started by this task.
By default, CloudNet only provides the "jvm" runtime, you can add your own with custom modules.

disableIpRewrite

Enables or disables the ip rewrite for services of this task (true/false) If this option is turned off, the port and IP in the server software configuration will not be changed by CloudNet.

Warning

We recommend the usage of this feature just in very special cases.
For example, when you want to have several proxies for the Bedrock Edition. (Unfortunately, the Bedrock Edition does not support SRV-Records. Please contact us in that case for further assistance!)

javaCommand

The path to the Java installation with which services of this task are started.

maintenance

Enables or disables the maintenance mode services of this task (true/false)

Info

If the maintenance mode is enabled, services of this task can have a special sign layout and users need the permission cloudnet.bridge.maintenance to join.

autoDeleteOnStop

This enables or disables the automatic deletion of service files after they have been stopped. (true/false)

Warning

Do NOT use this feature to keep persistent data of services like CityBuild. Please use static services instead!

staticServices

This enables or disables static services. (true/false)
If disabled, services will be started in the temp directory.
If enabled, services will be started in the local/services/ directory.

associatedNodes

Here you can specify on which nodes the services from this task should be started.
If you leave the option empty (as it is by default), the services can be started on every node.
Example (starting the services on Nodes 1, 2 and 4):

  "associatedNodes": [
    "Node-1",
    "Node-2",
    "Node-4"
  ],

groups

Here you can specify to which groups the task should belong.

deletedFilesAfterStop

Here you can specify files which should always be deleted after stopping the server.
This options works even when static services are enabled!

processConfiguration

environment

The environment services of this task should run in. Possible values are:

• MINECRAFT_SERVER
• GLOWSTONE
• NUKKIT
• GO_MINT
• BUNGEECORD
• VELOCITY
• WATERDOG

maxHeapMemorySize

This defines the memory size (RAM) for services of this task.

jvmOptions

Here you can set custom jvm options. (For example the Aikar garbage collector flags options)

processParameters

Here you can set custom process parameters.

startPort

This is the port from which the cloud will use ports for the services.
You can use the same start port for multiple tasks, the system will use the next available port.

minServiceCount

This defines the minimum amount of services that should be always online from this task.

includes

The includes provides the possibility to download files when each service is prepared.
Example:

  "includes": [
    {
      "url": "https://cloudnetservice.eu/cloudnet/versions.json",
      "destination": "plugins/versions.json",
      "properties": {}
    }
  ],

templates

This is an array of template configurations.
This means you can add multiple templates to one task. For example for different maps:

  "templates": [
    {
      "prefix": "BedWars",
      "name": "2x1",
      "storage": "local",
      "alwaysCopyToStaticServices": false
    },
    {
      "prefix": "BedWars",
      "name": "3x4",
      "storage": "local",
      "alwaysCopyToStaticServices": false
    }
  ]

deployments

The deployments provide the possibility to copy each service to a template when it is being shutdown.
Example:

  "deployments": [
    {
      "template": {
        "prefix": "Proxy",
        "name": "default",
        "storage": "local",
        "alwaysCopyToStaticServices": false
      },
      "excludes": [
        "whitelist.yml",
        "log.txt"
      ],
      "properties": {}
    }
  ],

properties

The properties can contain any json object which you can access through the api.
It contains some default values provided by us, but you can extend it with the API!

requiredPermission

This option sets a permission you need to be able to connect to the task.

Tip

If you set it to null (which is also the default), you do not need any permission to join the task!

Example:

    "requiredPermission": "your.join.permission",

smartConfig

Please take a look at the Smart Module for more information.
