CLI tool for publishing and subscribing to RabbitMQ.

Install

Install Cargo (Rust).

$ brew install rust

Install rabbiteer.

$ cargo install rabbiteer

Command format

The command has two "modes", publish and subscribe.

$ rabbiteer [general opts] publish/subscribe [specific opts]

General options

$ rabbiteer --help
...
OPTIONS:
    -h, --host <host>            RabbitMQ host [default: 127.0.0.1]
    -p, --password <password>    Password to authenticate with [default: guest]
    -P, --port <port>            Port to connect to [default: 5672]
    -U, --url <url>              AMQP connection url (amqp://user:pass@host:port/vhost)
    -u, --user <user>            User to authenticate with [default: guest]
    -v, --vhost <vhost>          Virtual host [default: ]

Environment variables

AMQP_URL

The connection string can be set using the AMQP_URL environment variable.

$ export AMQP_URL="amqp://joe:secret@myspecialhost/somevhost"
$ rabbiteer subscribe -e ttninjs-batch

CONF file

The connection can be specified in a JSON file pointed out by CONF environment variable.

$ cat conf-localhost.json
{
    "amqp": {
        "connection": {
            "host": "localhost",
            "vhost": "docker",
            "login": "admin",
            "password": "admin"
        }
    }
}
$ export CONF=conf-localhost.json
$ rabbiteer subscribe -e ttninjs-batch

Publish

Publishing pushes data from stdin or a file to an exchange.

$ rabbiteer publish --help
...
FLAGS:
    --rpc        Publish as RPC with replyTo and wait for reply.
OPTIONS:
    -c, --content-type <content_type>    Content type such as application/json. Inferred from filename if
                                         possible.
    -e, --exchange <exchange>            Exchange to publish to [default ]
    -f, --file <file>                    Filename (- is stdin) [default: -]
    -H, --header <header>...             Header on the form "My-Header: Value"
    -r, --routing-key <routing_key>      Routing key [default: ]
    -z, --priority <priority>            Priority
    -t, --rpctimeout <rpctimeout>        RPC timeout in milliseconds

Example

From stdin

Provide the content-type as arg.

$ echo "{\"panda\":true}" | \
    rabbiteer -u admin -p admin -v prod publish -e myexchange -c application/json

From a file

Content-type is inferred if possible.

$ rabbiteer -u admin -p admin -v prod publish -e myexchange -H "batch: true" -f ./foo.json

Supports RabbitMQ style RPC

Using the replyTo header.

$ CONF=conf.json rabbiteer publish -e myservice -r somecall --rpc -f ./foo.json

Calls myservice/somecall using the contents of file foo.json and sets up a replyTo header and waits the the rpc reply. The reply will be printed to stdout.

Subscribe

Subscribing binds an anonymous queue to an exchange and listens to messages pushed to that exchange. The messages can either be dumped to stdout or as files to a directory.

$ rabbiteer subscribe --help
...
FLAGS:
    -i, --info       Include delivery info (and headers).
OPTIONS:
    -e, --exchange <exchange>          Exchange to subscribe to
    -o, --output <output>              Output directory (- is stdout) [default: -]
    -r, --routing-key <routing_key>    Routing key [default: #]

Example

To stdout

Outputs the body of each message to stdout. Makes no conversion of the body. If the body is binary, you will see gibberish in the terminal.

$ rabbiteer -u admin -p admin -v prod subscribe -e myexchange
...
With delivery info

-i means we make a JSON wrapping of the message so we can include some basic information about the delivery.

This always produces a JSON structure. When the body is binary (as indicated by content_type), the data is base64 encoded and when the type is text/..., we output it as a JSON string.

The format is:

{
    "deliver":{
        "consumer_tag":"amq.ctag-Tjxx5Qy5zAr0o_yiLOsNEg",
        "delivery_tag":1,
        "redelivered":false,
        "exchange":"myexchange",
        "routing_key":"text"
    },
    "props":{
        "content_type":"application/json",
        "headers":{
            "backendUpdate":false,
            "batch":false,
            "index":"dist-text",
            "oper":"index"
        }
    },
    "data": "body"
}
$ rabbiteer -u admin -p admin -v prod subscribe -e myexchange -i
...

To a directory

With -o the body of each individual message is output to a separate file. The header fileName can be supplied by the sender, in which case that file is (over-)written.

$ rabbiteer -u admin -p admin -v prod subscribe -e myexchange -o /tmp
...
