✨ Overview

TerraDeploy is a unified multi-cloud infrastructure orchestration and lifecycle platform designed to deploy, manage, and audit resources across Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure.

With an integrated React/Next.js dashboard, secure pipelines, cost breakdown projections, and Open Policy Agent (OPA) validation constraints, TerraDeploy delivers GitOps best practices in one complete codebase.

🚀 Quick Start

📋 Prerequisites

• Terraform (>= 1.5.0)
• Node.js (>= 18.0.0)
• OPA CLI (optional, for local policy verification)

1️⃣ Run Local System Validation

Execute the setup tool to inspect local CLI runtimes and resolve dashboard modules:

chmod +x scripts/*.sh
./scripts/setup.sh

2️⃣ Configure Environment Parameters

Create and populate your variable files inside the environment folders:

• terraform/environments/dev/terraform.tfvars
• terraform/environments/staging/terraform.tfvars
• terraform/environments/prod/terraform.tfvars

3️⃣ Local Plan & Apply

Deploy the development stack locally:

./scripts/deploy.sh --env dev

4️⃣ Boot Web Dashboard Portal

Start the visualization user interface:

cd dashboard
npm run dev

The interface is exposed at http://localhost:3000.

---

🏗️ Cloud Account Setup & Auth

TerraDeploy communicates using native SDK parameters. Export the following keys locally or add them as GitHub Actions Secrets:

AWS Authentication

export AWS_ACCESS_KEY_ID="your-access-key"
export AWS_SECRET_ACCESS_KEY="your-secret-key"
export AWS_DEFAULT_REGION="us-east-1"

GCP Authentication

export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account.json"
export GCP_PROJECT_ID="your-project-id"

Azure Authentication

export ARM_CLIENT_ID="your-app-id"
export ARM_CLIENT_SECRET="your-app-password"
export ARM_SUBSCRIPTION_ID="your-sub-id"
export ARM_TENANT_ID="your-tenant-id"

---

⚙️ Environment Lifecycle

TerraDeploy segregates work environments using hard isolation parameters:

Parameter	Development	Staging	Production
Workspace	dev	staging	prod
Instance Type	t3.micro / e2-micro	t3.small / e2-medium	t3.medium / e2-standard-2
Database	Single Zone (Micro)	Single Zone	Multi-AZ High Availability
Deploy Rule	Local CLI or Push	Automated on Merges	Requires Manual approvals
Force Destroy	Allowed	Restricted	Banned

---

🛡️ Policy as Code & Security Scanning

Governance policies are enforced prior to resource allocation:

1. Public Storage Blocked: Disallows public-read S3 ACL policies.
2. Open Ingress Checked: Blocks exposing port 22 (SSH), 3389 (RDP), and 5432 (Postgres) globally (0.0.0.0/0).
3. IAM Least Privilege: Fails build if wildcard Action: * is coupled with Resource: * in policies.
4. Mandatory Tagging: Validates presence of Environment and Project tags.

Validate policies locally:

./scripts/verify.sh

---

🖥️ Next.js Web Interface

The integrated React Next.js dashboard features:

• State Parsing API: Reads .tfstate files directly to show resource count, IPs, and endpoints.
• Deploy SSE Terminal: Streams deployment outputs from CLI executions directly to the console UI.
• Cost breakdowns: Provides recommendations and burn forecast tracking charts.
• Compliance Panel: Visualizes vulnerabilities found in linter runs.
• Dark Mode Support: Smooth toggles for modern layouts.

---

🧰 Automation Scripts

• scripts/bootstrap.sh: Automatically provisions remote S3 buckets/DynamoDB locks for your state.
• scripts/deploy.sh: Runs local workspace plans, queries OPA policies, and applies infrastructure.
• scripts/destroy.sh: Handles resource terminations with confirmation validation.
• scripts/health-check.sh: Checks live endpoint status via network probes.
• scripts/cleanup.sh: Cleans local file workspace targets.

---

📊 Cost Optimization

TerraDeploy implements cost budgets through Infracost integration. It estimates budget changes on pull requests, compares monthly running costs across environments, and suggests rightsizing for underutilized instances.

---

🩺 Monitoring & Observability

Observability features:

• AWS: CloudWatch log groups and CPU utilization threshold alarms.
• GCP: Project-level logging sinks forwarding audit metrics to Cloud Storage.
• Azure: Log Analytics workspaces unified with Application Insights telemetry.

---

🔒 Security Policy

We enforce strict least-privilege permissions. All code commits should be signed. Dependabot updates libraries weekly, and CodeQL scans workflows for vulnerability alerts. Refer to the security policy document for details.

---

🗺️ Roadmap

• Dynamic Multi-tenant Environments: Launch environments directly from the UI.
• OpenID Connect (OIDC) Setup Helpers: Automatic CLI federation setup script.
• Slack/Teams Notification Routing: Multi-channel alerting integration.

---

❓ FAQ

How do I migrate from local state to remote state?

1. Execute ./scripts/bootstrap.sh --provider aws --env dev to build state storage.
2. Update the backend blocks inside the environment folder.
3. Execute terraform init -migrate-state.

How does the policy check fail the build?

The OPA agent returns a failure exit code if any resource changes violate constraints in infrastructure.rego. This stops the pipeline before terraform apply runs.
