How to Delete All Resources in GCP Using Script with Logging | Complete DevOps Guide by Eduarn

 

Managing cloud resources efficiently is a critical skill in today’s DevOps world. While creating infrastructure using automation tools is common, cleaning up resources properly is equally important to avoid unnecessary costs.

In Google Cloud Platform, there is no single command to delete all running services. However, with the right scripting approach, you can automate the cleanup process safely.

At Eduarn.com, we train professionals on real-world Cloud, DevOps, and AI scenarios, and this is one of the most practical scripts used in training labs and enterprise environments.

---

🔍 Why Resource Cleanup Matters

Failing to delete unused resources can lead to:

❌ Unexpected billing
❌ Security risks
❌ Resource sprawl
❌ Compliance issues

👉 Automating cleanup ensures cost optimization and governance

---

🧑‍💻 Prerequisites

Before running the script:

• Install Google Cloud SDK
• Authenticate:

gcloud auth login

• Ensure you have Owner or sufficient IAM permissions

---

🧾 Complete GCP Cleanup Script (With Logging)

This script deletes major resources and logs actions for tracking:

#!/bin/bash

PROJECT_ID="your-project-id"
LOG_FILE="gcp_cleanup.log"

echo "Starting cleanup for project: $PROJECT_ID" | tee -a $LOG_FILE
gcloud config set project $PROJECT_ID

echo "Deleting Compute Engine instances..." | tee -a $LOG_FILE
gcloud compute instances list --format="value(name,zone)" | while read NAME ZONE; do
  echo "Deleting VM: $NAME in $ZONE" | tee -a $LOG_FILE
  gcloud compute instances delete $NAME --zone=$ZONE --quiet
done

echo "Deleting Cloud Storage buckets..." | tee -a $LOG_FILE
for BUCKET in $(gcloud storage buckets list --format="value(name)"); do
  echo "Deleting bucket: $BUCKET" | tee -a $LOG_FILE
  gcloud storage buckets delete $BUCKET --quiet
done

echo "Deleting BigQuery datasets..." | tee -a $LOG_FILE
for DATASET in $(bq ls --format=prettyjson | jq -r '.[].datasetReference.datasetId'); do
  echo "Deleting dataset: $DATASET" | tee -a $LOG_FILE
  bq rm -r -f -d $PROJECT_ID:$DATASET
done

echo "Deleting Cloud SQL instances..." | tee -a $LOG_FILE
for SQL_INSTANCE in $(gcloud sql instances list --format="value(name)"); do

🔐 Owner Logging & Audit Benefits

This script includes logging using:

tee -a gcp_cleanup.log

Benefits:

• Track who deleted what
• Maintain audit trail
• Useful for compliance & enterprise governance
• Debug failed deletions

---

⚠️ Important Considerations

• Ensure you have Owner or Admin role
• Some resources (like VPCs, firewall rules) may need additional handling
• Always test in a non-production environment first

---

💡 Pro Tip from Eduarn.com

👉 If your goal is to delete everything quickly:

gcloud projects delete PROJECT_ID

Top Terraform + GCP Interview Questions (With Detailed Answers, Code & Use Cases) By EduArn

 

Mastering Terraform on Google Cloud Platform is not just about theory—it’s about real implementation.

At eduarn.com, we train learners using hands-on cloud labs + real enterprise scenarios across DevOps, AI, and Cloud.

---

🔹 1. What is Terraform? (Deep Answer + Use Case)

Terraform is a declarative Infrastructure as Code (IaC) tool. You define what infrastructure you want, and Terraform figures out how to create it.

✅ Use Case:

Provision a VM for a training lab automatically for 50 students.

resource "google_compute_instance" "vm" {
  name         = "training-vm"
  machine_type = "e2-medium"
  zone         = "us-central1-a"

  boot_disk {
    initialize_params {
      image = "debian-cloud/debian-11"
    }
  }

  network_interface {
    network = "default"
    access_config {}
  }
}

---

🔹 2. What is Terraform State? Why is it Critical?

Terraform state (terraform.tfstate) tracks:

• What resources exist
• Their configuration
• Their current status

⚠️ Problem Without State:

Terraform may recreate resources → data loss risk

✅ Best Practice (Remote State in GCP):

terraform {
  backend "gcs" {
    bucket  = "my-terraform-state-bucket"
    prefix  = "training/env"
  }
}

👉 Used in teams to avoid conflicts + enable locking

---

🔹 3. count vs for_each (With Real Scenario)

❌ count (index-based)

resource "google_storage_bucket" "buckets" {
  count = 3
  name  = "bucket-${count.index}"
}

✅ for_each (preferred)

variable "users" {
  default = ["user1", "user2"]
}

resource "google_storage_bucket" "buckets" {
  for_each = toset(var.users)
  name     = "bucket-${each.key}"
}

👉 Use Case:
Creating lab resources per student with unique names.

---

🔹 4. What are Modules? (Enterprise Use)

Modules = reusable Terraform code blocks.

✅ Example:

module "vm" {
  source = "./modules/vm"
  name   = "trainer-vm"
}

👉 Use Case at eduarn.com:

• Reusable modules for:
  • VM labs
  • IAM setup
  • Networking

👉 Reduces duplication across corporate batches

---

🔹 5. IAM Role Assignment (Real Scenario)

🎯 Requirement:

Assign “viewer” role to all students in a batch.

resource "google_project_iam_binding" "students" {
  project = "my-project"
  role    = "roles/viewer"

  members = [
    "user:user1@gmail.com",
    "user:user2@gmail.com"
  ]
}

👉 Use Case:

• Controlled access to labs
• Avoid giving admin permissions

---

🔹 6. Service Accounts (Important in DevOps)

Service accounts are used by applications—not humans.

resource "google_service_account" "app" {
  account_id   = "app-sa"
  display_name = "App Service Account"
}

👉 Use Case:

• CI/CD pipelines
• Automation scripts

---

🔹 7. Variables & Dynamic Config

variable "machine_type" {
  default = "e2-medium"
}

machine_type = var.machine_type

👉 Use Case:

• Same code for dev, test, prod
• Change config without rewriting code

---

🔹 8. Outputs (Important in Automation)

output "vm_ip" {
  value = google_compute_instance.vm.network_interface[0].access_config[0].nat_ip
}

👉 Use Case:

• Share VM IP with learners
• Integrate with LMS

---

🔹 9. Dependency Handling

resource "google_compute_instance" "vm" {
  depends_on = [google_service_account.app]
}

👉 Ensures:

• Service account created before VM

---

🔹 10. Workspaces (Multi Environment)

terraform workspace new dev
terraform workspace new prod

👉 Use Case:

• Separate environments for:
  • Training
  • Demo
  • Production

---

🔹 11. Secret Management (Critical)

❌ Avoid:

password = "123456"

✅ Use:

• Environment variables
• Secret Manager

👉 Prevents security risks

---

🔹 12. Real Training Use Case (End-to-End)

At eduarn.com, we use Terraform to:

✔️ Create 50+ users
✔️ Assign IAM roles
✔️ Provision lab VMs
✔️ Share access instantly

👉 Result:

• Lab ready in < 1 hour
• Zero manual effort
• Consistent environment
