Event-based Scripting for Kubernetes.

Brigade: Event-based Scripting for Kubernetes

Script simple and complex workflows using JavaScript. Chain together containers, running them in parallel or serially. Fire scripts based on times, GitHub events, Docker pushes, or any other trigger. Brigade is the tool for creating pipelines for Kubernetes.

• JavaScript scripting
• Project-based management
• Configurable event hooks
• Easy construction of pipelines
• Check out the docs to get started.

The Brigade Technology Stack

• Brigade ❤️ JavaScript: Writing Brigade pipelines is as easy as writing a few lines of JavaScript.
• Brigade ❤️ Kubernetes: Brigade is Kubernetes-native. Your builds are translated into pods, secrets, and services
• Brigade ❤️ Docker: No need for special plugins or elaborate extensions. Brigade uses off-the-shelf Docker images to run your jobs. And Brigade also supports DockerHub webhooks.
• Brigade ❤️ GitHub: Brigade comes with built-in support for GitHub, DockerHub, and other popular web services. And it can be easily extended to support your own services.

Quickstart

The easiest way to get started with Brigade is to install it using Helm:

$ git clone https://github.com/Azure/brigade.git
$ cd brigade
$ helm install --name brigade ./chart/brigade

You will now have Brigade installed.

To create new projects, use the brigade-project Helm chart. While inside the Git repository cloned above, run these commands:

$ helm inspect values ./brigade-project > myvalues.yaml
$ # edit myvalues.yaml
$ helm install --name my-project ./brigade-project -f myvalues.yaml

When editing myvalues.yaml, follow the instructions in that file for configuring your new project. Once you have customized that file, you can install the project based on your new configuration by passing it with -f myvalues.yaml.

Now creating your first brigade.js is as easy as this:

const { events } = require('brigadier')

events.on("exec", (brigadeEvent, project) => {
  console.log("Hello world!")
})

But don't be fooled by its simplicty. Brigade can be used to create complex distributed pipelines. Check out the tutorial for more.

brig: The Brigade client

Brigade is an event-driven system. Brigade projects live inside of your cluster. But it's easy to load and run brigade scripts with the brig client.

Building Brig

$ make bootstrap build-client
$ bin/brig --help

Running a simple Brig script

Assuming you have a project named my/project, you can run a brigade.js file like this:

$ brig run -f brigade.js my/project

This will show you the detailed output of running your project.

We suggest starting with the simple brigade.js script above, then heading over to the docs to learn more.

To see the names of your projects, run brig project list.

Brigade ❤️ Developers

These directions assume you are using minikube for development. For other environments, you must make sure you push the Docker images to the right registry or cluster Docker daemon.

To get started:

• Clone this repo and change directories into it
• Point to MiniKube's Docker environment with eval $(minikube docker-env)
• Run make bootstrap build docker-build to build the source
• Install the Helm chart: helm install -n brigade chart/brigade

Brigade is well-tested on Minikube and Azure Container Services.
