ExFlag

Goals:

• Retrieve a value from a server for a known key with optional host parameters
• This may include host name, environment, version, etc...
• Value is an atom (on / off, a / b / c, etc)

Non-Goals (right now)

• Provide offline storage / caching of keys

python server

#!/usr/bin/python3

from flask import Flask, request


app = Flask(__name__)
@app.route("/flags", methods=['POST'])
def get_flag():
    r_body = request.get_json()
    print(r_body)
    flag_key = r_body["key"]
    options = r_body["opts"]
    env = options.get("environment")

    if env == "production":
        return "{\"value\": \"on\"}", 200
    else:
        return "{\"value\": \"off\"}", 200
