# GitHub Actions
Provides an Arch Linux package for the GitHub Actions remote runner.
## Motivation
I wanted to use GitHub Actions remote runner to access the GPU on my server. Because of the security risks of having a public runner instance, I put it inside a `systemd-nspawn` container. I wanted a convenient way to install the GitHub Actions runner, so I decided to package it up.
## Installation
First, clone the repository:
git clone https://aur.archlinux.org/github-actions.git
The build and install it:
cd github-actions
makepkg -fi
Configure the daemon:
cd /opt/github-actions
./config.sh --token ...
Then start it up:
sudo systemctl enable --now github-actions
## Usage
You might want to combine this with a container. To create a container (including some suggested packages):
pacstrap -c github-actions base ruby clang pkg-build vim
Then, import it:
machinectl import-fs github-actions
Configure it:
$ cat /etc/systemd/nspawn/github-actions.nspawn
[Exec]
Boot=true
PrivateUsers=no
[Network]
Private=no
VirtualEthernet=no
[Files]
TemporaryFileSystem=/tmp
# Expose GPU:
Bind=/dev/nvidia0
Bind=/dev/nvidiactl
Boot it:
sudo systemctl enable --now systemd-nspawn@github-actions.service
### Limits
Limit the memory consumption of your container to 2 GiB:
systemctl set-property systemd-nspawn@myContainer.service MemoryMax=2G
Limit the CPU time usage to roughly the equivalent of 2 cores:
systemctl set-property systemd-nspawn@myContainer.service CPUQuota=200%
### Attaching Shell
sudo machinectl shell github-actions
