## Overview

This repository is a platform-engineering bootcamp: engineers provision cloud environments, deploy sample workloads, then explore their monitoring dashboards. The README documents the GCE web server and startup-installed monitoring tools, GKE sample applications, and GCP-native/Grafana dashboards for GCE, GKE, and Cloud Run. The tree also includes a separate GCE SRE-terminal example and Terraform-managed development VM. Source sampling was limited to the web page script, so links among unsampled deployment and dashboard files are shown only where documented or directly indicated by their roles.

Main entry points: [`gce/vm_debian/create_instance.sh`](https://github.com/jaichenchlani/sre_bootcamp/blob/master/gce/vm_debian/create_instance.sh) (Create Debian VM), [`iac/dev/compute_instance.tf`](https://github.com/jaichenchlani/sre_bootcamp/blob/master/iac/dev/compute_instance.tf) (Development VM config), [`gce/vm_debian/webserver_app/index.html`](https://github.com/jaichenchlani/sre_bootcamp/blob/master/gce/vm_debian/webserver_app/index.html) (Apache web app), [`gce/vm_debian/startup_script.sh`](https://github.com/jaichenchlani/sre_bootcamp/blob/master/gce/vm_debian/startup_script.sh) (VM startup setup)
