DevOps Platform Monorepo

This monorepo is a structured workspace for my continuous learning and experimentation in DevOps, Platform & Cloud Infrastructure.

Each major component in the repository is scoped to an area of practice and includes (or will include) its own README for detailed usage, configuration, and implementation notes.

---

Projects

GitHub Actions

Path: .github/workflows
Workflow automation for CI/CD pipelines. Demonstrates selective workflow triggering based on modified files in a commit.

---

Infrastructure as Code (Terraform)

AWS

Path: infra-as-code/providers/aws/modules

• eks.tf: EKS cluster provisioning
• vpc.tf: Custom VPC definition
• ebs.tf, iam.tf, karpenter.tf, metrics-server.tf, s3-state.tf: Supporting infrastructure modules

GCP

Path: infra-as-code/providers/gcp/modules

• gke.tf: GKE production-grade cluster
• Modules for networking, bastion, firewall rules, NAT, Traefik, Cloud Armor, service accounts

Azure

Path: infra-as-code/providers/azure/modules

• aks.tf: AKS cluster provisioning
• Modules for PostgreSQL, App Gateway, VNet, DNS zones, and storage

Templates for Environments

Path: infra-as-code/environments

• azure-template/: Base backend and main Terraform configs
• gcp-template/: Similar structure for GCP deployments

---

Kubernetes / Helm Microservices

Path: kubernetes/helm

• Parent Helm chart (Chart.yaml)
• Microservice subcharts:
  • kafka, opensearch, postgresql, rabbitmq, redis, tika
• Shared chart templates (_*.tpl) for deployments, services, configmaps, etc.
• Global templates: global-ingress.yaml, openshift-routes.yaml, secrets.yaml
• Test manifest: tests/test-connection.yaml

This structure supports consistent Helm chart composition across services using DRY principles.

---

Scripts

Path: scripts

• utils.sh: Shared utility functions
• format_all.sh: Format source code
• lint_all.sh: Run linters on the repository
• test_args.sh: Validate utils.sh argument handling
• clean_local_docker.sh: Cleanup script for Docker
• tunnel_service.sh: Port forwarding or tunneling logic
• wait_for_pod.sh: Waits for a Kubernetes pod to be ready
• migrate_repo.sh: Misc support script for repository migration
• site_status.sh: Checks the status of a site or service

---

Tools

Path: tools

Slack Alert

Path: tools/slack_alert
Sends Slack notifications from CI/CD pipelines for build status or other triggers.

Tavisod

Path: tools/tavisod
Python package for fetching secrets from Google Secret Manager.

• Python module under tavisod/
• setup.py and tests included

Google SQL Migrator

Path: tools/google_sql_migrator
Transfers data between Google Cloud SQL instances using local Postgres and Docker.

• Includes Dockerfile, database scripts, CLI, and requirements

Resources Calculator

Path: tools/resources
Calculates chart resource usage (calc_chart_resources.py).

Vulnerabilities Report

Path: tools/vulnerabilities
Scripted vulnerability scanner and report generator with PDF and HTML template output.

---

Miscellaneous

• git.config: Git configuration used locally
• requirements.txt: Python dependencies for repo-wide tools
• zshrc: Custom shell configuration

---

External Projects

These are other repositories I maintain separately from this monorepo you can find on my GitHub

---

Notes

• Each directory is self-contained and designed for modular usage or reuse.
• Terraform code follows provider/environment separation for flexibility.
• Scripts and tools are aligned with real-world DevOps automation tasks.
