CLI: update guide URLs to use the new path structure
the original paths, e.g. /streams.html, do have redirects
in place but it turned out to be a surprisingly fragile
Cloudflare feature when there are hundreds of them,
so we better switch now.

RabbitMQ CLI Tools

Build Status

This repository contains RabbitMQ CLI tools (rabbitmqctl and others).

This generation of CLI tools first shipped with RabbitMQ 3.7.0.

Goals

Team RabbitMQ wanted a set of tools that

  • Was extensible from/with plugins
  • Supported pluggable output formats (in particular machine-friendly ones)
  • Had good test coverage
  • Wasn't as coupled to the server repository
  • Could be used as a low risk vehicle for Elixir evaluation

Supported RabbitMQ Versions

Long lived branches in this repository track the same branch in RabbitMQ core and related repositories. So master tracks master in rabbitmq-server, v3.10.x tracks branch v3.10.x in rabbitmq-server and so on.

Please use the version of CLI tools that come with the RabbitMQ distribution version installed.

Building

Requirements

Building this project requires

  • Erlang/OTP 23.3 (or later)
  • Elixir 1.12.0 (or later).

Command line tools depend on rabbitmq-common. Dependencies are being resolved by erlang.mk

Building Standalone Executables

This repo produces a rabbitmqctl executable which can be used as different tools (rabbitmq-plugins, rabbitmq-diagnostics, rabbitmq-queues, rabbitmq-streams, rabbitmq-upgrade) by copying or symlinking it with different names. Depending on the name, a different set of commands will be loaded and available, including for --help.

To generate the executable, run

make

Usage

rabbitmqctl

See rabbitmqctl help and rabbitmqctl man page for details.

rabbitmq-plugins

See rabbitmq-plugins help and rabbitmq-plugins man page for details.

rabbitmq-diagnostics

See rabbitmq-diagnostics help and rabbitmq-diagnostics man page.

Testing

See CONTRIBUTING.md.

Developing

Adding a New Command

Conventions

RabbitMQ CLI tools use module name conventions to match the command-line actions (commands) to modules. The convention is outlined in the CommandBehaviour module.

Command Module Interface

Each command module must implement the RabbitMQ.CLI.CommandBehaviour behaviour, which includes the following functions:

  • validate(args, opts), which returns either :ok or a tuple of {:validation_failure, failure_detail} where failure detail is typically one of: :too_many_args, :not_enough_args or {:bad_argument, String.t}.

  • merge_defaults(args, opts), which is used to return updated arguments and/or options.

  • run(args, opts), where the actual command is implemented. Here, args is a list of command-specific parameters and opts is a Map containing option flags.

  • usage, which returns a string describing the command, its arguments and its optional flags.

  • banner(args, opts), which returns a string to be printed before the command output.

There are also a number of optional callbacks:

  • switches, which returns command specific switches.
  • aliases, which returns a list of command aliases (if any).
  • formatter: what output formatter should be used by default.
  • usage_additional: extra values appended to the usage output to provide additional command-specific documentation.
  • scopes: what scopes this command appears in. Scopes associate tools (e.g. rabbitmqctl, rabbitmq-diagnostics, rabbitmq-queues, rabbitmq-streams) with commands.
  • distribution: control erlang distribution. Can be :cli (default), :none or {:fun, fun}

Tutorial

We have a tutorial that demonstrates how to add a CLI command that deletes a queue.

Examples

See lib/rabbitmq/cli/ctl/commands/status_command.ex and test/status_command_test.exs for minimalistic but not entirely trivial examples.
