Cats Love Money 🐈‍⬛

Set of scripts to terminate various GCP resources to save cash and cats.

Currently we support deleting:

• Cloud Composer instances
• GKE clusters
• Cloud Compute instances
• Cloud Compute disks
• Cloud Dataproc clusters

The script by default deletes all resources older than one day. If you want to exclude the resource from being deleted you need to set a please-do-not-kill-me label on it.

Usage

Triggering manually

To use this tool manually do:

pip install -r requirements.txt
python main.py

Scheduling on GCP

You may consider deploying this script as a cloud function that will be then triggered on schedule using cloud scheduler. To do this execute:

TOPIC="delete_gcp_resources"
gcloud pubsub topics create "${TOPIC}"

gcloud functions deploy delete_gcp_resources \
    --runtime="python38" \
    --trigger-topic="${TOPIC}" \
    --timeout="500s"

gcloud scheduler jobs create pubsub delete_gcp_resources \
    --schedule="0 2 * * *" \
    --topic="${TOPIC}"
    --message-body="trigger"

or simply do

./deploy.sh

We are using Pub/Sub instead of http trigger as cloud workflows seems to have some hard times with permissions when invoking cloud functions.
