What is Poppy
|
|
============
|
|
|
|
Users have come to expect exceptional speed in their applications, websites, and video experiences. Because of this, using a CDN has become standard for companies, no matter their size.
|
|
|
|
Poppy will take all the guess work out of the CDN market for our users. Poppy will give them a consistently speedy experience from integrated partners, with an easy to use RESTful API.
|
|
|
|
Vendor lock-in to a particular CDN provider is removed by abstracting away the plethora of vendor API's available. This means that a customer only has to integrate with one CDN API, and reap the benefits of using multiple providers.
|
|
|
|
Your content can be distributed to multiple providers seamlessly instead of just one.
|
|
|
|
Running performance benchmarks against each configured CDN provider allows you to simply repoint your DNS at the new provider; and with that simple change you can ensure your application is running using the fastest provider at the time. It will also allow you to handle CDN failures and minimize disruption to your application from CDN outages.

What Poppy is not
|
|
----------------------
|
|
|
|
Poppy does not run its own Edge Cache or POP servers. This is purely a management API to abstract away the myriad of CDN providers on the market.
|
|
|
|
|
|
|
|
Getting Started
|
|
-------------------------------------------
|
|
|
|
**Note:** These instructions are for running a local instance of CDN and
|
|
not all of these steps are required. It is assumed you have `CassandraDB` and `Zookeeper`
|
|
installed and running in a Docker Container.
|
|
|
|
1. From your home folder create the ``~/.poppy`` folder and clone the repo::
|
|
|
|
$ cd
|
|
$ mkdir .poppy
|
|
$ git clone https://github.com/openstack/poppy.git
|
|
|
|
2. Copy the Poppy config files to the directory ``~/.poppy``::
|
|
|
|
$ cp poppy/etc/poppy.conf ~/.poppy/poppy.conf
|
|
$ cp poppy/etc/logging.conf ~/.poppy/logging.conf
|
|
|
|
3. Find the ``[drivers:storage:cassandradb]`` section in
|
|
``~/.poppy/poppy.conf`` and modify the URI to point
|
|
to your local casssandra cluster::
|
|
|
|
[drivers:storage:cassandra]
|
|
cluster = <docker ip>
|
|
keyspace = poppy
|
|
migrations_path = /home/poppy/poppy/storage/cassandra/migrations
|
|
automatic_schema_migration = True #True is recommended for local dev machine
|
|
|
|
|
|
5. For logging, find the ``[DEFAULT]`` section in
|
|
``~/.poppy/poppy.conf`` and modify as desired::
|
|
|
|
log_file = server.log
|
|
|
|
6. Change directories back to your local copy of the repo::
|
|
|
|
$ cd poppy
|
|
|
|
|
|
7. Install general requirements::
|
|
|
|
$ pip install -r requirements/requirements.txt
|
|
|
|
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 .
|
|
|
|
To install additional dependencies, see `Additional Dependencies`_.
|
|
|
|
|
|
8. Install and start cassandra and zookeeper driver::
|
|
|
|
$ pip install docker-compose
|
|
$ docker-compose -f docker/compose/dependencies.yml up -d
|
|
|
|
9. Start poppy task flow worker::
|
|
|
|
$ poppy-worker
|
|
|
|
10. Start the Poppy server::
|
|
|
|
$ poppy-server
|
|
|
|
11. Test out that Poppy is working by requesting the home doc (with a sample project ID)::
|
|
|
|
$ curl -i -X GET -H "X-Project-ID: 000" -H "X-Auth-Token: 000" -H "Content-Type: application/json" http://127.0.0.1:8888/v1.0/
|
|
|
|
You should get an **HTTP 200** along with some headers that will look
|
|
similar to this::
|
|
|
|
HTTP/1.0 200 OK
|
|
Date: Thu, 13 Feb 2014 14:34:21 GMT
|
|
Server: WSGIServer/0.1 Python/2.7.3
|
|
Content-Length: 464
|
|
Content-Type: application/json-home
|
|
Cache-Control: max-age=86400
|
|
|
|
12. To run unit/functional test::
|
|
|
|
$ tox
|
|
|
|
To run a full test suite with api test, you will need to put in correct
|
|
CDN vendor configuration (in ``~/.poppy/poppy.conf``) first, e.g::
|
|
|
|
[drivers:provider:fastly]
|
|
apikey = "<your_fastly_api_key>"
|
|
|
|
Then start a poppy server::
|
|
|
|
$ poppy-server -v
|
|
|
|
And run test suite with api test::
|
|
|
|
$ tox -- --exclude=none
|
|
|
|
|
|
Additional Dependencies
|
|
-----------------------
|
|
|

|
|
------------
|
|
|
|
For Python 2.7::
|
|
|
|
$ sudo apt-get install python-dev
|
|
|
|
For Python 3.4::
|
|
|
|
$ sudo apt-get install python3.4-dev
|
|

Installing Cassandra and Zookeeper Locally
|
|
------------------------------------------
|
|
|
|
We recommend running Cassandra and Zookeeper in a docker container when developing locally.
|
|
|
|
Follow the instuctions in the /poppy/docker/compose/README.md file for running Poppy locally.
|
|
|
|
|
|
Running tests
|
|
-----------------------------
|
|
|
|
First install the additional requirements::
|
|
|
|
$ pip install tox
|
|
|
|
And then run tests::
|
|
|
|
$ tox
|
|
|
|
|
|
.. _`CassandraDB` : http://cassandra.apache.org
|
|
.. _`pyenv` : https://github.com/yyuu/pyenv/
