Demo Repository: DevOps and SRE Showcase

Welcome to my demo repository! This repository serves as a showcase of my capabilities in the DevOps and Site Reliability Engineering (SRE) skillset. It demonstrates the deployment and orchestration of a Rust microservice in a cloud environment on Google Cloud Platform (GCP), incorporating various DevOps practices.

Repository Structure

• src directory: Contains the source code of a microservice written in Rust.

• terraform directory: Includes Terraform (HCL) code responsible for creating a cloud environment on Google Cloud. This environment comprises a Google Cloud project, a GKE (Google Kubernetes Engine) cluster, and a Google Container Registry.

• helm directory: Hosts a local Helm chart used to package the Rust microservice from the src directory.

• helm-values directory: Stores all the values files for Helm charts deployed via the Terraform Helm provider.

• .github/workflows directory: Houses various GitHub Actions workflows for automating tasks such as deploying infrastructure (via Terraform), creating and pushing Docker images to DockerHub, and deploying the application via Helm.

• DOCKERFILE: Contains the necessary information to package the application into a Docker container.

Showcase Overview

This demo illustrates a Rust microservice running on a GKE cluster created through Terraform. The infrastructure includes Service Mesh capabilities via Istio and Observability capabilities through Prometheus and Grafana monitoring tools.

Key Components

• Rust Microservice: The core functionality resides in the src directory, showcasing the implementation of a microservice using Rust.

• Terraform Infrastructure: The terraform directory demonstrates the infrastructure-as-code approach, creating a GCP project, a GKE cluster, and a Google Container Registry to host the microservice's Docker image.

• Helm Chart: The helm directory contains a local Helm chart, providing a convenient way to package, configure, and deploy the Rust microservice.

• GitHub Actions: Automation workflows in the .github/workflows directory showcase continuous integration and deployment practices. Actions include deploying infrastructure, building and pushing Docker images, and deploying the application via Helm.

DevOps Capabilities

• Service Mesh (Istio): The GKE cluster is configured with Istio for Service Mesh capabilities, enabling advanced traffic management, security, and observability.

• Observability (Prometheus and Grafana): Prometheus and Grafana are integrated to provide monitoring and observability insights into the microservice and infrastructure.
