RDS

Option to create RDS at

application launch:

String dbName =

System.getProperty("RDS_DB_NAME");

String userName = System.getProperty("RDS_USERNAME");

String password = System.getProperty("RDS_PASSWORD");

String hostname = System.getProperty("RDS_HOSTNAME");

String port = System.getProperty("RDS_PORT");

Grab connection details for use:

import os

if 'RDS_HOSTNAME' in os.environ:

DATABASES = {

'default': {

'ENGINE': 'django.db.backends.mysql',

'NAME': os.environ['RDS_DB_NAME'],

'USER': os.environ['RDS_USER'],

'PASSWORD’: os.environ['RDS_PASSWORD'],

'HOST': os.environ['RDS_HOSTNAME'],

'PORT': os.environ['RDS_PORT'],

}

}

Grab connection details from os.environ’s

commands:

syncdb:

command: "django-admin.py syncdb --noinput"

leader_only: true

option_settings:

"aws:elasticbeanstalk:application:python:environment":

DJANGO_SETTINGS_MODULE: "mysite.settings"

"aws:elasticbeanstalk:container:python":

WSGIPath: "mysite/wsgi.py"

Add “.ebextensions” directory Add “python.config” file

commands:

syncdb:

command: "django-admin.py syncdb --noinput"

option_settings:

"aws:elasticbeanstalk:application:python:environment":

DJANGO_SETTINGS_MODULE: "mysite.settings"

"aws:elasticbeanstalk:container:python":

WSGIPath: "mysite/wsgi.py"

RDS populated from Django model (use Django Evolution etc to upate when model changes)

production:

adapter: mysql2

encoding: utf8

database: <%= ENV['RDS_DB_NAME'] %>

username: <%= ENV['RDS_USERNAME'] %>

password: <%= ENV['RDS_PASSWORD'] %>

host: <%= ENV['RDS_HOSTNAME'] %>

port: <%= ENV['RDS_PORT'] %>

Update database.yml to include generated RDS details:

# Configure third-party service credentials

# Run rake tasks before an application deployment

container_commands:

01deploy:

command: rake my_deployment_tasks

# in environment variables:

option_settings:

- option_name: AIRBRAKE_API_KEY

value: MYAPIKEY

Add “.ebextensions” directory Add “.config” file

# Configure third-party service credentials

# Run rake tasks before an application deployment

container_commands:
