TAK Base Infrastructure

Modern AWS CDK v2 infrastructure for Team Awareness Kit (TAK) deployments

Overview

The Team Awareness Kit (TAK) provides Fire, Emergency Management, and First Responders an operationally agnostic tool for improved situational awareness and a common operational picture.

This repository deploys the foundational AWS infrastructure required for a complete TAK server deployment, including networking, compute, storage, and security services - all while using free and open source software.

It is specifically targeted at the deployment of TAK.NZ via a CI/CD pipeline. Nevertheless others interested in deploying a similar infrastructure can do so by adapting the configuration items.

Architecture Layers

This base infrastructure is the foundation of additional higher level layers, each deployed as a separate stack from its own repository. BaseInfra must be deployed first - every other layer imports its outputs via CloudFormation exports.

For the full layer diagram and deployment order across all TAK.NZ repositories, see the TAK.NZ organization overview. That diagram is maintained in one place so it stays current as layers are added - it lists BaseInfra (this repo), AuthInfra, TakInfra, CloudTAK, MediaInfra, and UtilsInfra, in deployment order.

Quick Start

Prerequisites

• AWS Account with configured credentials
• Public Route 53 hosted zone (e.g., tak.nz)
• Node.js and npm installed
• ECS Service-Linked Role: aws iam create-service-linked-role --aws-service-name ecs.amazonaws.com (first time only)
• For CI/CD deployment: See AWS & GitHub Setup Guide for multi-account OIDC configuration

Installation & Deployment

# 1. Install dependencies
npm install

# 2. Bootstrap CDK (first time only)
npx cdk bootstrap --profile your-aws-profile

# 3. Deploy development environment
npm run deploy:dev

# 4. Deploy production environment  
npm run deploy:prod

Infrastructure Resources

Networking

• VPC with IPv4/IPv6 dual-stack support
• Subnets - Public and private across 2 Availability Zones
• NAT Gateways - Environment-specific (1 for dev, 2 for prod)
• VPC Endpoints - S3 Gateway + Interface endpoints (prod only)

Compute & Storage

• ECS Cluster - Fargate-enabled for containerized applications
• S3 Bucket - Configuration storage with KMS encryption
• KMS Key & Alias - Application-specific encryption

Security & DNS

• ACM Certificate - Wildcard SSL covering multiple subdomains:
  • Main domain (e.g., tak.nz)
  • Wildcard (e.g., *.tak.nz)
  • Map services (e.g., *.map.tak.nz)
• Security Groups - Restrictive access controls
• IAM Policies - Least-privilege access patterns

Available Environments

Environment	Stack Name	Description	Domain
dev-test	TAK-Dev-BaseInfra	Cost-optimized development	dev.tak.nz
prod	TAK-Prod-BaseInfra	High-availability production	tak.nz

Development Workflow

New NPM Scripts (Enhanced Developer Experience)

# Development and Testing
npm run dev                    # Build and test
npm run test:watch            # Run tests in watch mode
npm run test:coverage         # Generate coverage report

# Environment-Specific Deployment
npm run deploy:dev            # Deploy to dev-test
npm run deploy:prod           # Deploy to production
npm run synth:dev             # Preview dev infrastructure
npm run synth:prod            # Preview prod infrastructure

# Infrastructure Management
npm run cdk:diff:dev          # Show what would change in dev
npm run cdk:diff:prod         # Show what would change in prod
npm run cdk:bootstrap         # Bootstrap CDK in account

Configuration System

The project uses AWS CDK context-based configuration for consistent deployments:

• All settings stored in cdk.json under context section
• Version controlled - consistent deployments across team members
• Runtime overrides - use --context flag for one-off changes
• Environment-specific - separate configs for dev-test and production

Configuration Override Examples

# Override domain name for custom deployment
npm run deploy:dev -- --context r53ZoneName=custom.tak.nz

# Deploy production with different VPC CIDR
npm run deploy:prod -- --context vpcCidr=10.5.0.0/20

# Use single NAT gateway instead of redundant setup for cost savings
npm run deploy:prod -- --context enableRedundantNatGateways=false

# Deploy with explicit environment type
npx cdk deploy --context envType=dev-test
npx cdk deploy --context envType=prod

Getting Help

Common Issues

• Route53 Hosted Zone - Ensure your domain's hosted zone exists before deployment
• AWS Permissions - CDK requires broad permissions for CloudFormation operations
