bbassieandClaude Opus 5 96362a2835 Wait for transitory instance statuses to settle
The config changed handler ran updateFactorioSettings and
updateFactorioWhitelist as soon as the field changed. While the instance
is starting, stopping, creating_save or exporting_data the server is not
ready for RCON, so the update threw and was only logged. The three list
update events pushed from the controller had the same problem, except
Link._processEvent swallowed the rejection and the update was lost
without a trace.

Add _waitForSettledStatus, which resolves once notifyStatus lands on
running or stopped. notifyStatus is the only place _status changes and
notifyExit always ends on stopped, so a waiter cannot hang. The settings,
whitelist and list updates now go through it.

Nothing is applied when the instance settles on stopped, because there is
no server to apply it to. factorio.settings is written to
server-settings.json and the lists to the list files on the next start,
and enableWhitelist is read from the config when the next Instance is
constructed.

The plugin hook now runs immediately for the two config fields instead of
being chained onto the update. Every other field already invokes it right
away, and waiting for the instance to settle would hold the notification
back for the whole startup.

Clusterio Host

Node hosting Factorio servers in a Clusterio cluster. Clusterio hosts connect to the controller and waits for commands from the controller to start up and stop instances. A cluster can have any number of hosts in it located on different computers, and each host can host any number of instances each of which is a Factorio server that talks with the rest of the cluster.

Usage

npx clusteriohost <command>

Common options:

  • --plugin-list <file> JSON file to use for storing the list of plugins that are available to the host. Defaults to plugin-list.json and will be created if it does not exist. See the plugin command for managing this list.

  • --config <file> JSON file to use for storing configuration for the host. Defaults to config-host.json and will be created if it does not exist. See the config command for inspecting and modifying the configuration.

plugin <command>

Configure plugins available to be loaded by the host. The available plugins will be loaded unless they have been disabled in the configuration, see the config command for disabling plugins.

plugin install <package>

Install a plugin from npm and add it to the plugin list. The package is passed to npm install --save so anything npm accepts works, including a version like @clusterio/plugin-subspace_storage@2.0.0. This command refuses to run outside the directory Clusterio was installed in, as the plugin has to end up in that directory's node_modules to be found.

For example, installing the Subspace Storage plugin:

npx clusteriohost plugin install @clusterio/plugin-subspace_storage

Since the plugin-list.json is shared between controller, host and ctl you usually only need to do this once per machine.

plugin add <path>

Add plugin either by require path or relative/absolute path to the plugin directory. A relative path must start with ./ or ../ (or .\ and ..\ on Windows) otherwise it will be assumed to be a require path for an installed package in node_modules. This is mainly useful for plugins under development, packages published on npm are better installed with plugin install.

For example, adding a plugin checked out in the external_plugins directory:

npx clusteriohost plugin add ./external_plugins/my_plugin

plugin remove <name>

Remove a plugin by its name. This should be done before uninstalling the plugin, otherwise there will be an error when Clusterio tries to load the info from the plugin. Removing and unistalling a plugin is usually not neccessary as the functions provided by the plugin can be disabled in the config.

For example, uninstalling the Subspace Storage plugin:

npx clusteriohost plugin remove subspace_storage
npm uninstall @clusterio/plugin-subspace_storage

Since the plugin-list.json is shared between controller, host and ctl you usually only need to do this once per machine.

plugin list

Lists the plugins set up to be available by name followed by path.

config

Manage the host configuration offline. This should only be used when the host is stopped, otherwise the config read might be out of date and config changes will be overwritten when the host shuts down.

config set <config-entry> [value]

Set a config entry to the given value. If value is not provided the entry is set to null. If the config entry is of type object the value must be a valid JSON serialization of an object.

See docs/configuration.md in the main repositiory for the available configuration.

config show <config-entry>

Shows the value for a single config entry.

config list

Lists up all configuration entries with their currently configured values.

run

Runs the host.
