Setting up a new x86_64 Linux CI server

Initial Setup

Order the server from Hetzner.

Choose a subdomain and add an A record in AWS Route 53 to point to it.

ssh root@zanic.ziglang.org
installimage

Choose latest stable Debian which is currently "bookworm".

In the settings editor, change the hostname (e.g. zanic.ziglang.org).

Reboot.

ssh root@zanic.ziglang.org

apt update
apt upgrade
apt install cmake ninja-build tidy git build-essential binaryen

adduser ci
passwd -d ci
su ci
cd

mkdir deps
cd deps
wget https://ziglang.org/deps/qemu-linux-x86_64-6.1.0.1.tar.xz
tar xf qemu-linux-x86_64-6.1.0.1.tar.xz
wget https://github.com/bytecodealliance/wasmtime/releases/download/v2.0.2/wasmtime-v2.0.2-x86_64-linux.tar.xz
tar xf wasmtime-v2.0.2-x86_64-linux.tar.xz
wget https://ziglang.org/deps/zig+llvm+lld+clang-x86_64-linux-musl-0.11.0-dev.1869+df4cfc2ec.tar.xz
tar xf zig+llvm+lld+clang-x86_64-linux-musl-0.11.0-dev.1869+df4cfc2ec.tar.xz
rm *.tar.xz

Then add as many runners as the hardware can handle.

Add a GitHub Actions Runner

New self-hosted runner

ssh root@zanic.ziglang.org
su ci
cd
# follow the snippet of code from the GitHub instructions

• Name of runner: make up something unique
• Add label: x86_64

Instead of their last ./run.sh step, do this, as root:

./svc.sh install ci
./svc.sh start ci
