Factorio Init

A factorio init script in bash

Requirements

The following software packages need to be installed:

• Wget

• cURL

• jq

• bash-completion (optional but recomended)

• for yum based systems do the following:

sudo yum install curl wget bash-completion jq

• for dnf based systems do the following:

sudo dnf install curl wget bash-completion jq

• for apt-get based systems do the following:

sudo apt-get install curl wget bash-completion jq

Debugging

If you find yourself wondering why stuff is not working the way you expect:

• Check the logs, I suggest you tail -f /opt/factorio/factorio-current.log in a separate session
• Enable debugging in the config and/or:
• Try running the same commands as the factorio user (/opt/factorio-init/factorio invocation will tell you what the factorio user tries to run at start)

/opt/factorio-init/factorio invocation
#  Run this as the factorio user, example:
sudo -u factorio 'whatever invocation gave you'
# You should see some output in your terminal here, hopefully giving
# you a hint of what is going wrong

Install

• Create a directory where you want to store this script along with configuration. (either copy-paste the files or clone from github):

cd '/opt'
git clone https://github.com/Bisa/factorio-init.git

• Rename or copy config.example to config and modify the values within according to your setup.

• Unless you need files from the extras dir (check the below sections) you can safely remove it.

Notes for users with an OS that has a older glibc version

The config has options for declaring an alternate glibc root. The user millisa over on the factorio forums has created a wonderful guide to follow on creating this alternate glibc root (side by side).

First-run

• If you don't have Factorio installed already, use the install command:

/opt/factorio-init/factorio install  # see help for options

• The installation routine creates Factorio's config.ini automatically.

• If you previously ran Factorio without this script, the existing config.ini should work fine.

Autocompletion

• Copy/symlink or source the bash_autocompletion file
• Ensure the factorio script is in your path

# either symlink:
ln -s /opt/factorio-init/extras/bash_autocomplete /etc/bash_completion.d/factorio
# or source:
echo "source /opt/factorio-init/extras/bash_autocomplete" >> ~/.bashrc

# then ensure factorio-init is added to your PATH, ie by:
ln -s /opt/factorio-init/factorio /usr/local/bin/factorio

# restart your shell to verify that it worked

Systemd

• Copy the example service, adjust & reload

cp /opt/factorio-init/extras/factorio.service.example /etc/systemd/system/factorio.service
# Edit the service file to suit your environment then reload systemd
systemctl daemon-reload

• Verify that the server starts

systemctl start factorio
systemctl status -l factorio
# Remember to enable the service at startup if you want that:
systemctl enable factorio

Note that systemd won't be able to keep track of the server process if you use this script to restart during updates. Use the config option UPDATE_PREVENT_RESTART=1 and implement your own stop/start logic to work around this.

SysvInit

• Symlink the init script:

ln -s /opt/factorio-init/factorio /etc/init.d/factorio
# Make the script executable:
chmod +x /opt/factorio-init/factorio
# Try it out:
service factorio help
# Do not forget to enable the service at boot if you want that.

Contributing

When contributing to this repo, please ensure your contribution is covered by at least one test in test/factorio.bats or the very least: do not create pull requests with failing tests, thank you.

Test the code

Testing is done using bats-core, bats-assert and bats-support.

• Write a test case, example:

@test "DEBUG=1 produces output" {
    # To access functions within ./factorio, source it then use the run command:
    source ./factorio
    export DEBUG=1
    run debug "TEST"
    # use the various asserts from bats-assert
    assert_output "DEBUG: TEST"
}

• init and update the submodules (if you did not already)

git submodule init
git submodule update

• Then run the tests, see the following sections:

With .githooks

• Set the hooks path to our .githooks directory

git config --local core.hooksPath extras/.githooks

The extras/.githooks/pre-commit will run shellcheck, local tests as well as docker tests with and without resources.

With Docker

• Build the docker image(s) (a slightly modified ubuntu/centos)

docker build --build-arg ubuntu_version=20.04 \
			 --build-arg factorio_version=1.1.30 \
			 --tag ubuntu-finit:latest - < extras/docker/Dockerfile.ubuntu
docker build --build-arg centos_version=centos8 \
			 --build-arg factorio_version=1.1.30 \
			 --tag centos-finit:latest - < extras/docker/Dockerfile.centos

Adding --target no-test-resources to the build command will avoid downloading test resources online but it will also skip tests that rely on the resources(!)

• Then run the image, mounting the current directory and removing the container once it's done

docker run -it --rm -v "$(pwd):/opt/factorio-init" --workdir /opt/factorio-init ubuntu-finit:latest extras/test
docker run -it --rm -v "$(pwd):/opt/factorio-init" --workdir /opt/factorio-init centos-finit:latest extras/test

Manually

Please note that some tests will be skipped unless you run them with the docker image or via .githooks, but running them manually is a quick way to get started.

• run the tests

./extras/test/libs/bats-core/bin/bats test

Using parallel, adding --jobs 10 to the above (adjust the number accordingly) will allow you to execute more tests in parallel and in turn possibly decrease the total time required to complete the run.
