# Keyard #
This project is a implementation of a Service Registry to work with the service discovery system.
# Getting started #
Aswe are not on pypi you need to clone this repo to use it
git clone email@example.com:rzanluchi/keyard.git
pip install .
Probably you want to use a virtualenv
# Configuring #
Keyard uses a json file configuration where you can set and etcd connection or use a in memory store
store_type can be 'etcd' or 'simple'
And to load the config create a python file like this bellow
from keyard import app
from keyard.helpers import config
app = app.create_app()
the create_app prepares all keyard resources and routes
# Running #
You will need some WSGI server like gunicorn
gunicorn your_file:app -b 0.0.0.0:8000
# How to use it? #
Now you have a service running at port 8000 and you have a resource on <host>:8000/keyard where you can perform all the valid operations
## GET ##
A get will return the list of the services available based on the query string parameters
* service_name -> name of the service you want (required)
* version -> version of the service you want (not required)
* load_balancer_strategy -> defines the load balancer strategy on server (not required)(only have 'random' for now)
Not using version will return all matches for the service_name for all version.
Not using load_balancer_strategy will return a list of all location available, using random the server chooses one and return it
## POST ##
A post will register a service on keyard. In the data you need service_name, version and a location. Version is not required and when not passe keyard assumes 1.0
## PUT ##
This method is intended for health_check calls. Health check calls are made to inform keyard that a location is still up.
It uses the same data as post.
## DELETE ##
A delete will remove a location from keyard. Uses the same data as post
# Example #
There is a example app for you to check. Start an etcd application localhost and
gunicorn example.keyard_app:app -b 0.0.0.0:8000
gunicorn example.app2:app -b 0.0.0.0:8002
gunicorn example.app1:app -b 0.0.0.0:8001
That curl should return you "Hello World"
