AWS Docker Config

This tool is designed to deliver an app's configuration from a central config database into the process environment for an app. This tool enables Twelve-Factor style configuration for apps running on EC2.

Install

Setup steps:

• Create DynamoDB table
• Creating IAM Role with access to the DynamoDB table
• Downloading ADF-CONFIG onto the EC2 instance

Database Setup

Create a table named adf-config with a hash key of App and a range key of Value.

IAM Role

Create an IAM role with the following policy:

{
  "Version": "timestamp",
  "Statement": [
    {
      "Action": [
        "dynamodb:Scan"
        "dynamodb:PutItem",
        "dynamodb:DeleteItem"
      ],
      "Sid": "Stmt:timestamp:0",
      "Resource": [
        "*"
      ],
      "Effect": "Allow"
    }
  ]
}

Then be sure to boot your EC2 instances with a role that has this policy.
