Requirements

These scripts depends on boto3 package, the AWS SDK for Python and require Python 2.6+. You can install boto3using yum

$ yum install python2-boto3

or using pip

$ pip install boto3

AWS configuration

Create an Access Key

To use AWS API calls you need to make your account reachable with an Access Account.

See the Security Credentials page for more information on getting your keys. For more information on configuring boto3, check out the Quickstart section in the developer guide.

Configure credentials

You need to set up your AWS security credentials previously created to allow the API calls.

Guided configuration

You can use the AWS CLI to configure aws credentials. In that case you need to install the awscli with yum

$ yum install -y awscli

or pip

$ pip install awscli --upgrade --user

Now run aws configure and fill the fields ACCESS_KEY, SECRETand REGION.

$ aws configure

Your aws profile is ready.

Manual configuration

On Linux environments fill the configuration file at ~/.aws/credentials with your credentials previously made :

$ vi ~/.aws/credentials

[default]
aws_access_key_id = <your access key id>
aws_secret_access_key = <your secret key>

(optionnal) You can also fill the ~/.aws/config file to set your region on default profile

$ vi ~/.aws/config

[default]
region = <your aws region> # e.g. region = eu-central-1

Your aws profile is ready.

Running the scripts

Delete VPCs resources

Beware! You need to provide AWS Access Key with high rights elevation.

Description

Name: delete_vpcs.py Description: Clear non-default resources on the region (from your profile or in parameter of the script). Technical: This script mainly uses boto3.resource class to instanciate AWS entities. Parameters:

• --check : (none) Enable check mode and do not apply deletions
• --region_name <region> : (string) Name of the (only one) AWS Region (e.g. eu-west-1, eu-central-1)

Usage

Run on a specific region (parameter override profile)

$ ./delete_vpcs.py --region_name=eu-central-1

List resources with their owner

Description

Name: list_region_vpc.py Description: List non-default VPCs and instances (for the moment) with their creator in order to trace who created it. Technical: This script mainly uses boto3.resource class to instanciate AWS entities. Parameters:
