esFrontLine

Limit restful requests to backend ElasticSearch cluster: Queries for the public,

Requirements

Python 2.7 or 3.6.2+
An ElasticSearch cluster to forward queries to

Install

I will assume you have Python installed (if not, here are Windows7 instructions)

pip install esFrontLine

Setup

You must write your own setting.json file with the following properties set:

elasticsearch - (Array of) ElasticSearch nodes
elasticsearch.host - URL of the ElasticSearch node that will accept query requests
elasticsearch.port - port for ES (default = 9200)
flask - flask.run() parameters (default port = 5000)
whitelist - list of indexes that are allowed
users - list of allowed HAWK users, with their linked resources
users.resources - list of indexes the user is allowed
users.hawk - object of Hawk credentials
users.hawk.id - any human readable name to identify the user or application
users.hawk.key - the secret value held by both endpoints and not shared with anyone
users.hawk.algorithm: always "sha256" for now
debug - for debugging

Here is an example of my settings.json file

{
    "elasticsearch":[{
        "host":"http://elasticsearch4.metrics.scl3.mozilla.com",
        "port":9200
    },{
        "host":"http://elasticsearch5.metrics.scl3.mozilla.com",
        "port":9200
    },{
        "host":"http://elasticsearch7.metrics.scl3.mozilla.com",
        "port":9200
    },{
        "host":"http://elasticsearch8.metrics.scl3.mozilla.com",
        "port":9200
    }],
    "flask":{
        "host":"0.0.0.0",
        "port":9292,
        "debug":false,
        "threaded":true,
        "processes":1
    },
    "users": [
      {
        "hawk": {
          "id": "kyle@example.com",
          "key": "secret",
          "algorithm": "sha256"
        },
        "resources": [
          "testing"
        ]
      }
    ],
    "whitelist":["bugs", "org_chart", "bug_summary", "reviews"],
    "debug":{
        "log":[{
            "filename": "./tests/results/logs/app.log",
            "maxBytes": 10000000,
            "backupCount": 200,
            "encoding": "utf8"
        },{
            "stream":"sys.stdout"
        }]
    }

}
