Brig: The Brigade CLI

Brig is a command line tool for interacting with Brigade. It allows Brigade users to learn about their projects and builds, and provides a convenient way to execute scripts.

Basic Usage

Creating a project

To create a project with brig, run brig project create and follow the interactive prompts, supplying project name, GitHub repo details (if not derived from project name), optional secrets and optional advanced configuration.

An example setup might look like the following:

$ brig project create
? VCS or no-VCS project? VCS
? Project name brigadecore/empty-testbed
? Full repository name github.com/brigadecore/empty-testbed
? Clone URL (https://github.com/your/repo.git) https://github.com/brigadecore/empty-testbed.git
? Add secrets? No
Auto-generated a Shared Secret: "FweBxcwJvcbTTuW5CquyPtHM"
? Configure GitHub Access? No
? Configure advanced options No

To read more about project configuration, see projects.

Running scripts

Brig has built-in help text that you can access easily by adding -h or --help to any command (e.g. brig -h or brig project -h). One of the most frequent usages of Brig is to send a script to the server.

This example program sends a Brigade JavaScript file to a brigade server.

Example usage:

$ brig run my-org/my-project

The above will load the local ./brigade.js to Brigade and execute it within the project my-org/my-project.

By default, Brig requests that the event exec be run. You can override this by supplying a --event=NAME flag. For example, try executing the following script:

const { events } = require('brigadier');

events.on('exec', () => {
  console.log('Hello from brig!');
});

A more complete example:

$ brig run --file my/brigade.js --namespace my-builds technosophos/myproject

The above looks for ./my/brigade.js and sends it to the Brigade server inside of the Kubernetes my-builds namespace. It executes within the project technosophos/myproject.

The output of the master process is written to STDOUT.

Starting the Brigade web dashboard

Brig comes with a web dashboard, Kashti, which can be launched using the brig dashboard command. The dashboard runs in your Kubernetes cluster, and Brig creates a tunnel, on localhost, then opens the default browser. On top of the global settings of Brig (the Kubernetes context, config, and namespace), the port of the local tunnel and disabling the launch of the default browser can be configured with flags.

$ brig dashboard --help
Flags:
  -h, --help             help for dashboard
      --open-dashboard   open the dashboard in the browser (default true)
      --port int         local port for the Kashti dashboard (default 8081)

$ brig dashboard
Connecting to kashti at http://localhost:8081...
Connected! When you are finished with this session, enter CTRL+C.

Starting the Brigade CLI dashboard

Brig also comes with a CLI dashboard that communicates directly with the Brigade API. This dashboard is an integration of the community project Brigadeterm, and can be launched using the brig term command. The refresh interval of the dashboard can be passed as a flag to the brig term command.

How Brig Works

Brig uses your $KUBECONFIG to find out about your Kubernetes cluster. It then authenticates directly to Kubernetes and interacts with Brigade and Kubernetes APIs.
