Shell Scripts for GCP Resource Management

This directory contains individual shell scripts for creating and managing single resources in Google Cloud Platform (GCP) using the gcloud command-line interface (CLI).

Directory Structure

The scripts are organized by resource type:

• aim: Scripts for Identity and Access Management (IAM)
• google-kubernetes: Scripts for Google Kubernetes Engine (GKE)
• load_balancer: Scripts for creating and managing load balancers
• net: Scripts for networking resources (VPC, firewall rules, etc.)
• sql: Scripts for Cloud SQL instances
• storage: Scripts for Cloud Storage buckets
• vm: Scripts for Compute Engine virtual machines

Usage

Most scripts can be executed directly after setting the necessary environment variables. For example:

# Set required environment variables
export SERVICE_ACCOUNT_NAME="your-service-account@your-project.iam.gserviceaccount.com"
export KEY="ssh-rsa AAAA..."

# Run a script
cd vm
./create_vm.sh

Common Environment Variables

Many scripts require the following environment variables:

• SERVICE_ACCOUNT_NAME: The email address of the service account to use
• KEY: Your SSH public key for VM access
• USER: Your username for SSH access

Notes

• These scripts are designed for demonstration and learning purposes
• Always review scripts before running them in a production environment
• Some scripts may need modification to work with your specific GCP project configuration
