Buildkite Agent

Note: This is the development branch of the buildkite-agent, and may not contain files or code in the current stable release.

The buildkite-agent is a small, reliable, and cross-platform build runner that makes it easy to run automated builds on your own infrastructure. It’s main responsibilities are polling buildkite.com for work, running build jobs, reporting back the status code and output log of the job, and uploading the job's artifacts.

Full documentation is available at buildkite.com/docs/agent

Installing

The agents page on Buildkite has personalised instructions for installing the agent with Ubuntu (via apt), Debian (via apt), macOS (via homebrew), Windows and Linux. You can also run the agent via Docker.

Starting

To start an agent all you need is your agent token, which you can find on your Agents page within Buildkite.

buildkite-agent start --token

Development

These instructions assume you are running a recent macOS, but could easily be adapted to Linux and Windows.

# Make sure you have go 1.11+ installed.
brew install go

# Download the code somewhere, no GOPATH required
git clone https://github.com/buildkite/agent.git
cd agent

# Create a temporary builds directory
mkdir /tmp/buildkite-builds

# Build an agent binary and start the agent
go build -i -o /usr/local/bin/buildkite-agent .
buildkite-agent start --debug --build-path=/tmp/buildkite-builds --token "abc"

# Or, run the agent directly and skip the build step
go run *.go start --debug --build-path=/tmp/buildkite-builds --token "abc"

Dependency management

We're using Go 1.13+ and Go Modules to manage our Go dependencies. We are keeping the dependencies vendored to remain backwards compatible with older go versions.

If you are using Go 1.11+ and have the agent in your GOPATH, you will need to enable modules via the environment variable:

export GO111MODULE=on

If you introduce a new package:

go get github.com/my/new/package

Then you can write that package to the vendor/ with:

go mod vendor
