Azure Decommission Old Snapshots

This repository automates the cleanup of outdated Azure snapshots by identifying and listing snapshots older than a specified number of days. It uses Azure Resource Graph queries to fetch snapshot details and logs the results for further processing.

Features

• Identify Azure snapshots older than a specified number of days.
• Fetch subscription IDs dynamically using subscription names.
• Paginated querying for large datasets to handle thousands of snapshots efficiently.
• Logging support for debugging and monitoring.

Prerequisites

1. Python: Ensure Python 3.8+ is installed.
2. Azure CLI: Install and authenticate using the Azure CLI.
3. Azure SDK for Python: Install the required Azure SDK libraries.
4. Environment Variables: Create a .env file with the following variables:
   • AZURE_CLIENT_ID
   • AZURE_TENANT_ID
   • AZURE_CLIENT_SECRET
   • LOGGING_CONFIG=logging-conf.yaml

Installation

1. Clone the repository:

   git clone https://github.com/githubofkrishnadhas/azure-decommision-old-snapshots.git
   cd azure-decommision-old-snapshots

2. Install the required packages:

   poetry install

3. Set up logging configuration:

   Ensure logging-conf.yaml exists in the root directory or provide a custom path via the LOGGING_CONFIG environment variable.

4. Initiate poetry venv

   poetry shell

5. Run the script:

   poetry run python snapshot.py --subscription_name SUBSCRIPTION_NAME --days DAYS --dry_run

• --dry_run: If specified, the script will only log the snapshots that would be deleted without actually deleting them. This is useful for testing and verification before performing the actual deletion.

File Structure

• snapshot.py: Main script for identifying and processing old snapshots.
• resourcegraph.py: Contains functions to query Azure Resource Graph for subscriptions and snapshots.
• setup_logging.py: Configures logging for the application.
• README.md: Documentation for the repository.
