Introduction

Johanna is a collection of boilerplate Python scripts that can do provisioning/deprovisioning of a simple backend system using AWS.

The backend includes below:

• VPC with two public subnets, two private subnets, routing tables, an internet gateway, a nat gateway and an EIP.
• IAM roles for Elastic Beanstalk
• EC2 key pair (SSH key)
• An Elastic Beanstalk application and an environment for Python Django API server

You can do provisioning/deprovisioning/reprovisioning of the whole system or partial at once. Especially, the reprovisioning of Django API server means a 'continuous deployement'.

How To Play

Using Lili(Vagrant provisioning script) is the simplest way to get a playground.

1. follow Lili README manual
2. on Vagrant VM(Ubuntu 16.04)

   1. sudo su

   2. cd /opt/johanna

   3. execute 'conf.py' to configure your aws environment.

      ./conf.py --accesskey YOUR_AWS_ACCESSKEY --secretkey YOUR_AWS_SECRETKEY --region AWS_REGION_NAME --az1 AVAILABILITY_ZONE_1 --az2 AVAILABILITY_ZONE_2 --cname CNAME --db DB_ENGINE --user DB_USER --pw DB_PASSWORD
      

      [Example]

      ./conf.py --accesskey ... --secretkey ... --region ap-northeast-2 --az1 ap-northeast-2a --az2 ap-northeast-2c --cname dv-nova --db mysql --user db-user --pw db-password
      

   4. ./run.py

You can use this on web GUI

Notes

• If you use AWS IAM user credential instead of master account, it must have IAMFullAccess, AWSElasticBeanstalkFullAccess and PowerUserAccess permissions.
