This is the official Cloud Foundry CLI (cf) version 9, a Go-based command-line tool for managing Cloud Foundry platforms. It provides a comprehensive set of commands for interacting with Cloud Controller (V2 and V3 APIs), UAA for authentication, networking policies, routing, and service brokers. The CLI supports application lifecycle management (push, scale, restart, logs), organization and space management, service instance and broker management, security groups, quotas, buildpacks, domains, routes, and plugins. The architecture follows a layered pattern: commands (in `command/v7/` and legacy `cf/commands/`) delegate to an actor layer (`actor/v7action/`, `actor/v7pushaction/`) which in turn uses API clients (`api/cloudcontroller/ccv3/`, `api/uaa/`, `api/cfnetworking/`, `api/router/`). HTTP clients are wrapped with middleware for authentication, retry, and logging. The codebase is heavily tested with unit tests (using counterfeiter fakes) and integration tests (Ginkgo/Gomega) that run against live or simulated CF environments. Key entry points include `main.go` which dispatches to either the V7 command parser or legacy V2 parser. The V7 commands are registered in `command/common/command_list_v7.go` and each command embeds a `BaseCommand` that provides shared setup (UI, config, actors). The push workflow is particularly complex, involving manifest parsing, resource matching, package creation, staging, and deployment via an event-driven pipeline in `actor/v7pushaction/`. External dependencies include Cloud Controller API, UAA, Log Cache, Networking Policy API, and Routing API. The CLI also supports a plugin system via RPC. The codebase is actively maintained with recent commits and CI workflows, though it carries legacy V2 code that is being gradually replaced by the V7 architecture.

This repository contains the source documentation for the Cloud Foundry Developer Guide, published at https://docs.cloudfoundry.org/devguide/. It consists of Markdown files with ERB templating (.html.md.erb) that generate static HTML documentation covering Cloud Foundry application deployment, management, and troubleshooting topics. The documentation is organized into sections such as deploy-apps, services, and capi, detailing workflows like cf push, manifest usage, service binding, routing, logging, and deployment strategies. The architecture relies on ERB templating for reusable components (partials) and follows a static site generation model. Key entry points include index.html.md.erb and section indexes like deploy-apps/index.html.md.erb. The documentation references external dependencies such as the Cloud Foundry CLI, CAPI V3 API, and BOSH properties, but does not contain executable code itself. It serves as a reference for developers interacting with the Cloud Foundry platform-as-a-service. While the documentation exhibits good organizational patterns and reuse of templated snippets, it shows signs of maintenance lag. The repository appears stale with no evidence of recent commits (last commit date provided is implausibly future-dated), and content risks drifting from the active Cloud Foundry platform due to version-specific references (e.g., cf CLI v8, deprecated stacks) and experimental features. However, the source structure demonstrates solid documentation engineering practices through modular partials and consistent formatting.
