python-aws-terminate-ec2

Used to decommission instances.

Testing in Python virtual environment using python version 3.6

Getting Started

Virtual environment

python3.6 -m venv env source env/bin/activate pip install --upgrade awscli pip install --upgrade pip pip install --upgrade boto3

Environment Variables

To ensure the code can easily be re-used I have set all the key elements as variables. These can also be defined as variables in any automation software.

Key	Value
dry_run	True or False - if yes the code will only check for access
search_tag	Tag to search for instances, e.g. Name
search_value	Value in search_tag to search for instances
snap_prefix	Snapshot description
arole	Role to assume across accounts
accounts	list of accounts to process using above role e.g ['0000000000000','1111111111111','2222222222222222','333333333333333333']

Process Flow

1. For each account listed
2. Retrieve instance details from instances which fulfil the filter rules
3. For each instance
4. Shutdown if running
5. Change EBS deleteontermination to True if False
6. Snapshot EBS volume(s)
7. Terminate Instance(s)

Known issues

None

Completed enhancements

1. Setup to use tags instead of input file
2. Setup to use a role rather than AWS CLI credentials.
3. Configure to use an array of accounts.
4. remove the counts and instead use the cli wait commands (new post code writing)
5. Rewrite in python

Planned enhancements

None presently
