Zaqar

Message queuing service for OpenStack. To find more information read our wiki.

Running a local Zaqar server with MongoDB

Note: These instructions are for running a local instance of Zaqar and not all of these steps are required. It is assumed you have MongoDB installed and running.

1. From your home folder create the ~/.zaqar folder and clone the repo:

   $ cd
   $ mkdir .zaqar
   $ git clone https://github.com/openstack/zaqar.git

2. Copy the Zaqar config files to the directory ~/.zaqar:

   $ cp zaqar/etc/zaqar.conf.sample ~/.zaqar/zaqar.conf
   $ cp zaqar/etc/logging.conf.sample ~/.zaqar/logging.conf

3. Find [drivers] section in ~/.zaqar/zaqar.conf and specify to use mongodb storage:

   storage = mongodb

   Then find the [drivers:storage:mongodb] section and modify the URI to point to your local mongod instance:

   uri = mongodb://$MONGODB_HOST:$MONGODB_PORT

   By default, you will have:

   uri = mongodb://127.0.0.1:27017

4. For logging, find the [DEFAULT] section in ~/.zaqar/zaqar.conf and modify as desired:

   log_file = server.log

5. Change directories back to your local copy of the repo:

   $ cd zaqar

6. Run the following so you can see the results of any changes you make to the code without having to reinstall the package each time:

   $ pip install -e .

7. Start the Zaqar server with logging level set to INFO so you can see the port on which the server is listening:

   $ zaqar-server -v

8. Test out that Zaqar is working by creating a queue:

   $ curl -i -X PUT http://127.0.0.1:8888/v1/queues/samplequeue -H
   "Content-type: application/json"

You should get an HTTP 201 along with some headers that will look similar to this:

HTTP/1.0 201 Created
Date: Fri, 25 Oct 2013 15:34:37 GMT
Server: WSGIServer/0.1 Python/2.7.3
Content-Length: 0
Location: /v1/queues/samplequeue

Running tests

First install additional requirements:

pip install tox

And then run tests:

tox -e py27

You can read more about running functional tests in separate TESTS_README.
