+# Factorio
+
+[![Install from Ansible Galaxy](https://img.shields.io/badge/role-bplower.factorio-blue.svg)](https://galaxy.ansible.com/bplower/factorio/)
+![Ansible Lint](https://github.com/bplower/ansible-factorio/workflows/Ansible%20Tests/badge.svg)
+
+A role for creating Factorio servers
+https://galaxy.ansible.com/bplower/factorio/
+
+## Requirements
+
+No requirements
+
+## Role Variables
+
+Variables can be roughly divided into two groups: deployment configurations and
+Factorio configurations.
+
+### Deployment Configurations
+
+The deployment configurations are all related to the way in which ansible
+installs the factorio server. These should be abstracted enough to allow
+multiple factorio servers to be run simultaneously.
+
+```
+server_sources: "/opt/games/sources/factorio"
+server_version: "0.17.79"
+download_url: "https://www.factorio.com/get-download/{{ server_version }}/headless/linux64"
+service_name: "factorio-server"
+service_user: "factorio"
+service_group: "factorio"
+service_root: "/home/{{ service_user }}"
+service_port: 34197
+service_restart_permitted: true
+factorio_default_save: "{{ service_root }}/factorio/saves/default-save.zip"
+factorio_target_save: "{{ factorio_default_save }}"
+```
+
+More detailed information about these variables is as follows:
+
+- Variable: `server_sources`<br>
+  Default: `"/opt/games/sources/factorio"`<br>
+  Comments: <br>
+  Where to cache server binaries downloaded from the download_url
+
+- Variable: `server_version`<br>
+  Default: `"0.17.79"`<br>
+  Choices:
+  - "0.18.26"
+  - "0.17.79"
+  - "0.17.74"
+  - "0.16.51"
+  - "0.15.40"
+  - "0.14.23"
+  - "0.13.20"
+  - "0.12.35"
+
+  Comments:<br>
+   You must set the `download_checksum` value if you set this variable. This
+   value is used in the default `download_url`.
+
+- Variable: `download_url`<br>
+  Default: `"https://www.factorio.com/get-download/{{ server_version }}/headless/linux64"`<br>
+  Comments:<br>
+  The URL to download the server binary from. This will only be downloaded if
+  the path `"{{ server_sources }}/factorio-{{ server_version }}.tar.gz"` does
+  not exist.
+
+- Variable: `download_checksum`<br>
+  Default: `"sha256:9ace12fa986df028dc1851bf4de2cb038044d743e98823bc1c48ba21aa4d23df"`
+  Comments:<br>
+  The checksum that must match the downloaded server binary. This ensures the integrity.
+  If you change the `download_url` or `server_version`, you need to adapt the checksum as well. To get the
+  checksum of a server binary, you can use `curl --silent --location <download_url> | sha256sum`.
+  To disable the checksum verification, just set it to an empty string (`""`).
+
+- Variable: `service_name`<br>
+  Default: `"factorio-server"`<br>
+  Comments:<br>
+  The name of the service to create. Multiple instances of factorio servers can
+  be run on a single host by providing different values for this variable (See
+  the examples section of this document).
+
+- Variable: `service_user`<br>
+  Default: `"factorio"`<br>
+  Comments:<br>
+  The user the service should be run as.
+
+- Variable: `service_group`<br>
+  Default: `"factorio"`<br>
+  Comments:<br>
+  The group the service user should be a member of.
+
+- Variable: `service_root`<br>
+  Default: `"/home/{{ service_user }}"`<br>
+  Comments:<br>
+  The directory in which to store the contents of the factorio zip file
+  downloaded from the server. This will result in the factorio resources being
+  stored at `{{ service_root }}/factorio/`.
+
+- Variab: `service_port`<br>
+  Default: `34197`<br>
+  Comments:<br>
+  The port to host the service on. This default is the factorio default value.
+
+- Variable: `service_restart_permitted`<br>
+  Default: `true`<br>
+  Comments:<br>
+  Setting this to `false` will prevent the service from being restarted if
+  changes were applied. This allows settings to be applied in preparation for
+  the next service restart without immediately causing service interruption.
+
+- Variable: `factorio_default_save`<br>
+  Default: `"{{ service_root }}/factorio/saves/default-save.zip"`<br>
+  Comments:<br>
+  The default save file used by the server.
+
+- Variable: `factorio_target_save`<br>
+  Default: `"{{ factorio_default_save }}"`<br>
+  Comments:<br>
+  The save file to be run by the server. This distinction is provided to
+  facilitate switching between multiple save files.
+
+### Factorio Configurations
+
+Settings for various config files can be set in dictionaries loosely named after
+the file. Each dictionary starts with `factorio_` followed by the filename
+(excluding the filetype extension) where hyphens ( - ) are replaced by
+underscores ( _ ). For example, the `server-settings.json` file is associated
+with the dictionary variable `factorio_server_settings`.
+
+The `default/` folder contains serveral files showing example dictionaries
+representing the values provided by the Factorio servers various examples JSON
+files.
+
+The following is a list of config files that have been implemented:
+
+- Filename: `server-settings.json`<br>
+  Variable: `factorio_server_settings`<br>
+  Example:
+  ```
+  factorio_server_settings:
+    name: "My Public Server"
+    max_players: 10
+    game_password: "mypassword"
+    visibility:
+      public: true
+      lan: true
+  ```
+
+- Filename: `server-whitelist.json`<br>
+  Variable: `factorio_server_whitelist`<br>
+  Example:
+  ```
+  factorio_server_whitelist:
+  - Oxyd
+  ```
+
+- Filename: `map-settings.json`<br>
+  Variable: `factorio_map_settings`<br>
+  Example:
+  ```
+  factorio_map_settings:
+    pollution:
+      enabled: false
+  ```
+
+- Filename: `map-gen-settings.json`<br>
+  Variable: `factorio_map_gen_settings`<br>
+  Example:
+  ```
+  factorio_map_gen_settings:
+    water: "high"
+    autoplace_controles:
+      coal:
+        size: "very-low"
+  ```
+
+## Example Playbooks
+
+An out of the box example might look as follows:
+
+```
+---
+- name: Create a default factorio server
+  hosts: localhost
+  roles:
+  - role: bplower.factorio
+```
+
+An example with a non-default port, and customized name:
+```
+---
+- name: My slightly changed factorio server
+  hosts: localhost
+  roles:
+  - role: bplower.factorio
+    service_port: 12345
+    factorio_server_settings:
+      name: "My factorio server"
+```
+
+An example of multiple servers on a single host:
+```
+---
+- name: Factorio farm
+  hosts: localhost
+  roles:
+  - role: bplower.factorio
+    service_port: 50001
+    service_name: factorio_1
+    service_root: /home/{{ service_user }}/{{ service_name }}
+  - role: bplower.factorio
+    service_port: 50002
+    service_name: factorio_2
+    service_root: /home/{{ service_user }}/{{ service_name }}
+```

+# Development & Contributions
+
+I don't use this project regularly anymore, but I try to keep it up to date when
+possible. If you have any issues or questions about it, I encourage you to open
+a PR or issue.
+
+## Testing
+
+This role uses yamllint for yaml validation, and molecule + docker for testing.
+Both tools can be installed using the `dev-requirements.txt` file. You will need
+to install docker separately.
+
+```
+pip install -r dev-requirements.txt`
+```
+
+Grouping all supported platforms together caused issues for CI, so the test are
+split into 3 scenarios based on the platforms being tested.
+
+The makefile can be used to start each of the tests, and supports a helpmenu with
+descriptions for each target:
+
+```
+$ make help
+
+Usage:
+  make
+
+Targets:
+  help        Display this help
+  lint        Lint yaml files
+  test_all    Run all molecule tests
+  test_centos  Run molecule centos tests
+  test_debian  Run molecule debian tests
+  test_ubuntu  Run molecule ubuntu tests
+```
