Description=Ephemeral GitHub Actions runner
After=network-online.target
Wants=network-online.target
# cloud-final runs the provision user data, which writes
# /etc/ephemeral-github-runner.env and the drop-ins below. Ordering after it
# makes the runner come up configured on first boot, no restart needed.
# (cloud-init's `systemctl restart` in user data remains as the bridge for
# images built before this ordering existed.)
After=cloud-final.service

[Service]
Type=simple
# The toolchain lives in the image at /opt/cargo/bin (the Dockerfile's ENV
# PATH does not survive materialization onto the host). Publish it here so
# every runner job inherits it. /etc/ephemeral-github-runner.env currently
# carries the same PATH line as a bridge for images built before this
# directive existed; EnvironmentFile is applied after Environment=, and the
# two values are kept identical, so there is no conflict.
Environment=PATH=/opt/cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
EnvironmentFile=/etc/ephemeral-github-runner.env
ExecStart=/opt/ephemeral-github-runner/start-runner.sh
Restart=no
# If the kernel OOM killer kills a job child (rustc/cargo), keep the runner
# service alive so the job is reported as a normal failure with logs instead
# of the runner vanishing and GitHub reporting a cancellation. cloud-init's
# oom.conf drop-in carries the same directive for images built before this.
