nithin-bose/ec2-auto-scaler

An auto-scaling alternative to elastic load balancer in EC2 for web applications using HAProxy

Requirements

You need to have HAProxy installed.

• Ubuntu

    $ sudo apt-get install haproxy
  

Installation

$ git clone git@github.com:nithinbose87/ec2-auto-scaler.git && cd ec2-auto-scaler
$ python setup.py install

Configuration

By default ec2-auto-scaler uses the example/config.ini file or use --config option to specify the config file.

Usage

ec2-auto-scaler is designed to run as a daemon from the load balancer itself.

To start daemon:

$ python ec2-auto-scaler.py start

To stop daemon:

$ python ec2-auto-scaler.py stop

To restart daemon:

$ python ec2-auto-scaler.py restart

To know the status:

$ python ec2-auto-scaler.py status

scaling_interval in the main section of the config file can be used to set the freequency of scaling checks.

For example, to run every 5 minutes, set scaling_interval as follows:

[main]
scaling_interval: 300
