 ## Important notice

-This is the development branch for factorioClusterio 2.0 which is currently undergoing heavy restructuring and refactoring.
-Expect plugins and existing installations to frequently break when using this branch.
-If you don't want to be an alpha tester for 2.0 please use the stable [1.2.x branch][1.2.x] or [latest stable release](https://github.com/clusterio/factorioClusterio/releases/latest).
+Clusterio 2.0 is still in alpha, however the previous stable has been abandoned and is no longer supported.
+Despite being alpha it's reasonably stable now and there's no major breakages expected before a stable release of 2.0.
+If you are starting a new cluster it's highly recommended to use the 2.0 alpha.

-Installation instructions below are for the unstable master branch.

 ## Running Clusterio

-After following the installation and master configuration instructions you can use the following commands to run Clusterio.
+After completing the installation start up the master server and at least one slave separately.
+The installer provides the `run-master` and `run-slave` scripts to make this simple.
+Once the master process is running you can log into the web interface which is hosted by default on http://localhost:8080/ (adjust the port number if you changed it), use the admin authentication token provided from the installation to log in.
+
+The basics of setting up a Factorio server from the web interface is to create an instance, assign it to a slave and then click start.


-### Master Server
+## Setting up remote slaves

-It's necessary to run the master server in order for anything to work.
-Once you've completed the setup run the following command to start it up:
-
-    npx clusteriomaster run
+Run the installer as described in the installation section and choose "Slave only" as the operating mode to install, it'll ask for a master URL and an authentication token.
+The URL is the same as what is needed to connect to the web interface, and the athentication token can be generated on the Slaves page in the web interface.
+Once you start up the slave it should show up in the Slaves list and be available for assigning and running instances on.


-### Slaves
+## Setting up clusterioctl

-Slaves connect to the master server and are managed remotely from the master server.
-In order for slaves to connect to the master server they need a valid authentication token, you can create a slave config with a valid token with the following command.
+There's a command line interface available for Clusterio which is installed separately with the same installer as for the master and slave.
+Run the installer as described in the installation section and choose "Ctl only" as the operating mode to install, you can do this in the same directory as you have installed other clusterio component(s) to.
+The installer will ask for a master URL and an authentication token, these are the same as you would use to connect to the web interface.
+If you want to use a different user for the command line interface you can generate an authentication token for an existing user with

-    npx clusterioctl slave create-config --name Local --generate-token
-
-This will write a new `config-slave.json` file in the current directory (you can change the location with the `--output` option) with the name, token and url to connect to the master server with.
-If you are making the config for a remote slave you will need to have set the `master.external_address` option to the URL the master server can be reached on.
-
-You can list the config of a slave on the slave itself with the `npx clusterioslave config list` command.
-See the [readme for @clusterio/slave](/packages/slave/README.md) for more information.

-### Instances
-
-Instances are created, managed and started from the master server.
-For now the only interface available is the `clusterioctl` command line tool included in Clusterio.
-You can run this tool from any slave, or the master server without having to set up a config, if you want to manage the cluster from somewhere else you will need to set the `control.master_url` and `control.master_token` options with the  `node clusterioctl control-config set` command:
-
-The basic operations to start a new instance is the following
-
-    npx clusterioctl instance create "My instance"
-    npx clusterioctl instance assign "My instance" "Local"
-    npx clusterioctl instance start "My instance"
-
-The first line creates the instance configuration on the master server.
-The second assigns the instance to a slave which creates the instance directory and files needed to run the instance on the given slave.
-The third line starts the instance, which creates a new save if there are no save games present.
-
-There are many more commands available with clusterioctl.
-See the [Managing a Cluster](/docs/managing-a-cluster.md) document or `npx clusterioctl --help` for a full list of them.

 This works for master plugins, and the metric will be automatically available through the /metric HTTP endpoint.

 For metrics that are per-instance, you must define an `instance_id` label and set it accordingly, for example:

 For a command the `definition` is the arguments to pass to [yargs.command](http://yargs.js.org/docs/#api-reference-commandcmd-desc-builder-handler) (see also [yargs.positional](http://yargs.js.org/docs/#api-reference-positionalkey-opt) and [yargs.options](http://yargs.js.org/docs/#api-reference-optionskey-opt) for setting up positional and optional arguments to commands).
 The `handler` is an async function that's invoked when the command is executed and it's passed the parsed command line arguments and a reference to the `Control` class of clusterioctl.

Hornwitser	90a400b782	Handle mod not found in data export Handle the case of the mod file not being found from the mod version. This could happen if the naming scheme is weird or the mod is unpacked.	2021-06-26 17:59:48 +02:00
Hornwitser	80eae94fe1	Handle leading zeros in mod filenames It's possible to put leading zeroes in the names of mod zip files which cause the existing algorithm to find the mod zip from the mod version to fail. Fix by listing the mods directory and fixing the version numbers for any of the mods with leading zeros in them.	2021-06-26 17:59:48 +02:00
Hornwitser	5daa492f68	Emitt more useful error on parse error Rethrow parse errors with the JSON content that failed to parse for JSON content sent to Clusterio from Factorio.	2021-06-26 17:59:48 +02:00
Hornwitser	b43a181bf4	Fix JSON serialization in export mod Fix incorrect serialization of control characters to \xHH escapes since JSON only support \uHHHH escapes, and serialization of infinite and NaN numbers.	2021-06-26 17:59:48 +02:00

Hornwitser	ea77e09058	Show upload progress Add progress bar for file uploads in progress and notify user if the upload fails.	2021-06-21 16:59:36 +02:00
Hornwitser	5ab4b95e3c	Support non-standard zip mime types in save upload Browser like Chrome doesn't use the application/zip mime type when uploading .zip files. Add support for application/x-zip-compressed to the save upload endpoint.	2021-06-21 16:59:36 +02:00
Hornwitser	8dc1415404	Skip slaveUpdateEventHandler test on Windows Due to the lack of a simple way to automate graceful shutdown of a slave on Windows causing the test to be unreliable, skip it on Windows.	2021-06-21 16:59:04 +02:00
