Download the PHP package jonpugh/github-runner without Composer

github-runner-starter

A single Bash script to install, configure, optionally launch, and clean up GitHub self-hosted runners. It automates:

• Downloading the proper Actions Runner build for your OS/arch
• Getting a registration token via the GitHub API
• Configuring the runner with your repository, name, and labels
• Optionally launching run.sh and handling cleanup on exit

This project also includes a minimal Docker setup for local testing and examples.

Features

• One-command setup for a self-hosted runner
• Works with environment variables or CLI flags (or a .env file)
• Automatically detects architecture (x64/arm64) and latest runner release
• Graceful stop/cancel handlers that can remove the runner and unregister it
• Optional Docker compose example for running/scaling multiple runners

Requirements

• Bash, curl, tar
• jq (used to parse GitHub API responses)
• Network access to GitHub
• A GitHub Personal Access Token (classic) or PAT with appropriate scopes: needs repo access and "self-hosted runners" administration for the target repository. Practically, you’ll want a token that can create registration tokens on the repository (often described here as admin:write on the repo in this script’s messages).

Installation

You can use the script directly, or install it via Composer so github-runner-starter is available on your PATH.

Option A: Use the script directly

• Clone or download this repository.
• From the project root, run:
  • ./github-runner-starter --help

Option B: Composer

If Composer is available in your environment:

• Add as a dependency or install globally. The package exposes a bin named github-runner-starter.

composer.json excerpt:

Quick start

1) Ensure you have a suitable PAT and know the owner/repo you want to register the runner to. 2) In a working directory, create a .env file or pass flags (see below). 3) Run the script.

Example with flags, including launching the runner immediately:

If you omit --run, the script will download and configure the runner, but not launch run.sh. You can start it later manually from the runner directory.

CLI options and environment variables

All options can be provided either as CLI flags or via environment variables. A .env file in the current working directory will be sourced automatically.

• --runner-path (env: RUNNER_PATH)
  • The path where the runner files will be downloaded/extracted (default: runner).
• --cleanup-runner (env: RUNNER_CLEANUP)
  • When canceling with Ctrl+C, remove the downloaded runner directory. Set value to yes to enable.
• --token (env: GITHUB_TOKEN)
  • GitHub API token used to obtain the registration token for the runner. Required when configuring.
• --repo (env: GITHUB_REPOSITORY)
  • Target repository, e.g., owner/repo. Required when configuring.
• --name (env: RUNNER_CONFIG_NAME)
  • Runner name. Defaults to $(whoami)@$(hostname -f).
• --labels (env: RUNNER_CONFIG_LABELS)
  • Comma-separated labels. Defaults to $(whoami)@$(hostname -f) and the runner name is also appended.
• --run (env: RUNNER_RUN)
  • If set, the script will launch run.sh after configuration completes.
• --config-sh-options (env: RUNNER_CONFIG_OPTIONS)
  • Extra options to append to the runner’s config.sh command.
• --no-config (env: RUNNER_CONFIG)
  • Skip the config.sh step. Useful if you only want to download/extract the runner.
• --help
  • Show inline help.

See .env.example for a full set of variables and inline documentation.

How it works

At a high level the script does the following: 1) Verify inputs, source .env if present, and compute defaults. 2) Request a short-lived registration token from the GitHub API for the given repository. 3) Determine the latest runner version and your architecture. 4) Download the appropriate runner tarball if not already present and extract it. 5) Run the runner’s config.sh with your parameters and labels. 6) Optionally start run.sh and wait on it.

On SIGTERM (stop) the script attempts to stop the runner and unregister it using config.sh remove with the same registration token. On SIGINT (Ctrl+C/cancel) it can optionally delete the runner directory if RUNNER_CLEANUP=yes is set.

Examples

• Configure only (no immediate run):

• Configure and run:

• Custom path and labels:

• Pass extra options to config.sh:

Docker usage (optional)

This repository includes a Dockerfile and docker-compose.yml for testing/development.

• Build and run with docker compose:

The compose file passes through GITHUB_TOKEN and targets this repo by default. You can override env vars via your shell or a .env file.

• Scaling multiple runners: The whichami helper in this repo, used by docker-entrypoint, creates a unique suffix for the runner name when scaling services:

Each container will get a distinct RUNNER_CONFIG_NAME like runner1@hostname, runner2@hostname, etc.

Note: The provided Docker image is for development. It installs dependencies and runs as the runner user in /github-runner-starter.

Troubleshooting

• "GITHUB_REPOSITORY is required": Provide --repo=owner/repo or set GITHUB_REPOSITORY.
• "GITHUB_TOKEN is required": Provide --token=... or set GITHUB_TOKEN. Ensure it has sufficient permissions to create a registration token for the repo.
• "Unable to get registration token": Often indicates insufficient token scope, wrong repo, or network issues. The script will echo the API response for details.
• "Unable to determine CLI version": Ensure your token can access the actions/runner releases API endpoint and network egress is available.
• Architecture errors: The script detects uname -m as x86_64 (x64) or arm64. Other architectures are not handled.

Security considerations

• Treat GITHUB_TOKEN as sensitive. Avoid committing it to source control or baking it into images.
• When using Docker, prefer passing the token via environment at runtime, not building it into the image.
