Project history

Apache Brooklyn's root README describes the platform as a system that supports blueprints in YAML or Java, deploys them to many clouds and target environments, monitors deployments, maintains a live model, and runs autonomic policies to keep applications healthy.

The CLI client is a separate Apache Brooklyn sub-project, written in Go. Its README says the repository contains the CLI client for Apache Brooklyn and can be built directly with Maven or inside Docker.

Official CLI docs describe `br` as a Brooklyn command-line client application. The command set covers login, deploying YAML blueprints, listing applications, reading sensors and config, invoking effectors, catalog operations, activity logs, policies, entity trees, and version checks against a running Brooklyn server.

Adoption history

Brooklyn's packaging history reflects a classic Apache server-plus-client split. The official docs list platform-specific CLI downloads for Windows, Linux, and OS X, and also note that the client binaries are included inside the Apache Brooklyn distribution under `bin/brooklyn-client-cli/`.

Homebrew packages only the CLI formula as `apache-brooklyn-cli`, exposing the `br` executable for users who want to operate a Brooklyn server without installing the full distribution locally.

How it is used

The basic workflow is `br login <URL> [username [password]]`, followed by commands such as `br deploy`, `br application`, `br catalog`, `br sensor`, `br effector`, and `br config`. The official docs note that username and password can be omitted when connecting to a localhost server with no security enabled.

The CLI is not the Brooklyn server itself. It is a remote-control tool for a running Brooklyn instance, so its package value is in scripting, automation, and inspecting cloud application state from a terminal.

Why package nerds care

The package is interesting because it is a narrow client extracted from a larger Java-based Apache platform. Installing a small Go CLI through Homebrew gives operators the useful terminal surface of Brooklyn without pulling in the full server runtime.

It also shows the older Apache cloud-management era in package form: YAML blueprints, jclouds-style locations, application trees, effectors, sensors, catalog items, and server-side config exposed through one `br` command.

Timeline

• 2014: Apache Brooklyn NOTICE files identify Apache Software Foundation copyright beginning in 2014.
• 2019: Official CLI reference source in brooklyn-docs records `br` command documentation metadata.
• 2020: Brooklyn docs build metadata shows the published GitBook-era latest docs and CLI pages.
