cfengine 0.9.0

Human-oriented CLI for interacting with CFEngine tools

CFEngine command line interface (CLI)

A CLI for humans to interact with CFEngine, enabling downloading and installing packages, building policy sets, deploying, and enforcing policy. It is practically a wrapper around our other tools, like cf-agent, cf-hub, cf-remote and cfbs.

Warning: This is an early version. Things might be missing or changed. Proceed with caution and excitement.

Installation

Install using pip:

pip install cfengine

Usage

Run the CFEngine agent - evaluate and enforce policy

cfengine run

CFEngine CLI help

cfengine help

Print CFEngine CLI version

cfengine run

Automatically format source code

cfengine format

Check for errors in source code

cfengine lint

Note that since we use a different parser than cf-agent / cf-promises, they are not 100% in sync. cf-agent could point out something as a syntax error, while cfengine lint does not and vice versa. We aim to make the tree-sitter parser (used in this tool) more strict in general, so that when cfengine lint is happy with your policy, cf-agent will also accept it. (But the opposite is not a goal, that cfengine lint must accept any policy cf-agent would find acceptable).

Build a policy set

cfengine build

(This is equivalent to running cfbs build).

Supported platforms and versions

This tool will only support a limited number of platforms, it is not intended to run everywhere CFEngine runs. Currently we are targeting:

• Officially supported versions of macOS, Ubuntu, and Fedora.
• Officially supported versions of Python.

It is not intended to be installed on all hosts in your infrastructure. CFEngine itself supports a wide range of platforms, but this tool is intended to run on your laptop, your workstation, or the hub in your infrastructure, not all the other hosts.

Backwards compatibility

This CLI is entirely intended for humans. If you put it into scripts and automation, expect it to break in the future. In order to make the user experience better, we might add, change, or remove commands. We will also be experimenting with different types of interactive prompts and input.
