ec2-boto3-provision

Provision ec2 on-demand or spot instances with python boto3

History

This script was created as I need to migrate a number of boxes from one AWS account to another in a very short time frame. I would have used Ansible but we were limited to pre 2.0 version that didn't support SSO Saml authentication (a requirement of the destination account)

There are a number of other approaches which could be a better solution.

• Terraform
• Cloudformation
• Ansible (needs v2.0+ for SAML)

See Terraform vs Ansible vs Cloudformation

This script reads a simple YAML file containing security group and instance definitions and provisions and tags them.

Authentication

The script assumes you have authenticated with aws and have a local .aws/credentials file

Running the script

$ python2.7 ec2_provision.py --help
usage: ec2_provision.py [-h] [--verbose] [--profile PROFILE] --definitions
                    DEFINITIONS [--add_security_groups] [--add_instances]

EC2 Utilities to manage security groups and instances

    optional arguments:
      -h, --help            show this help message and exit
      --verbose, -v         Verbose Logging

                            EC2 Authentication profile (.aws/credentials)

      --definitions DEFINITIONS, -d DEFINITIONS

                            YAML defintion file with security groups and instances
