GCP Organization Cleaner

GCP Organization Cleaner is a command-line tool designed to help you purge all resources within a GCP organization. Its ultimate goal is to support the cleanup of E2E test deployments.

Features

Deletes:

• custom roles
• firewall policies
• folders
• log sinks
• organization policies
• projects
• secure tags

Prerequisites

• Python 3.x
• Virtual Environment: Create and activate a virtual environment:

python3 -m venv ~/.envs/gcp-org-cleaner
source ~/.envs/gcp-org-cleaner/bin/activate
pip install -r requirements.txt

• Authentication: Ensure that your environment is authenticated to use the Google Cloud SDK. You can achieve this by running gcloud auth application-default login.
• Permissions: The user or service account running the script needs at least the following permissions at the organization level:
  • roles/compute.securityAdmin (For deleting firewall policies)
  • roles/logging.admin (For deleting log sinks)
  • roles/orgpolicy.policyAdmin (For deleting organization policies)
  • roles/resourcemanager.folderAdmin (For listing resources in folders)
  • roles/resourcemanager.organizationAdmin (For deleting projects and other organization-level resources)
  • roles/resourcemanager.tagAdmin (For deleting secure tags)
  • roles/iam.roleAdmin (For deleting custom roles)
  • roles/cloudasset.viewer (For searching resources using Cloud Asset Inventory)

Grant your Organization Administrator user the required permissions by running the following commands:

# set variable for current logged in user
export CURRENT_USER=$(gcloud config list --format 'value(core.account)')

# find and set your org id
gcloud organizations list
export ORG_ID=123456

# set needed roles
export ROLES="roles/compute.securityAdmin roles/logging.admin roles/orgpolicy.policyAdmin roles/resourcemanager.folderAdmin roles/resourcemanager.organizationAdmin roles/resourcemanager.tagAdmin roles/iam.roleAdmin roles/cloudasset.viewer"

for role in $ROLES; do
  gcloud organizations add-iam-policy-binding $ORG_ID \
    --member user:$CURRENT_USER --role $role --condition None
done

python main.py <organization_id> [options]

Delete only organization policies and log sinks (dry-run):

python main.py <organization_id> --dry-run --only-orgpolicies --only-logsinks

Delete log sinks, with exceptions:

python main.py <organization_id> --exclude-log-sinks=<sink1,sink2> --only-logsinks

Exclude specific custom roles

python main.py <organization_id> --exclude-custom-roles='organizations/123456789/roles/CustomRole1,organizations/123456789/roles/CustomRole2' --only-customroles

Exclude specific projects

python main.py <organization_id> --exclude-projects='project-1,project-2' --only-projects
