Story 7.4: Docker and Deployment

Metadata

• Story ID: 7.4
• Title: Docker and Deployment
• Epic: 7 - Testing, Documentation & CI/CD
• Status: Pending
• Priority: High
• Estimated Time: 6-8 hours
• Dependencies: All previous epics

Goal

Create production-ready Docker images and comprehensive deployment guides.

Description

This story creates multi-stage Dockerfiles, Docker Compose files, and deployment guides for various platforms.

Deliverables

1. Docker Images

• Create multi-stage Dockerfile:
  • Build stage with Go
  • Runtime stage (distroless)
  • Health checks
  • Proper layer caching

2. Docker Compose

• Create docker-compose.yml for development:
  • Platform service
  • PostgreSQL
  • Redis
  • Kafka (optional)
• Create docker-compose.prod.yml for production

3. Deployment Guides

• docs/deployment/kubernetes.md:
  • Kubernetes manifests
  • Helm chart (optional)
  • Service definitions
  • ConfigMap and Secret management
• docs/deployment/docker.md:
  • Docker Compose deployment
  • Environment variables
  • Volume mounts
• docs/deployment/cloud.md:
  • AWS/GCP/Azure deployment notes
  • Managed service integration
  • Load balancer configuration

4. Developer Experience

• Create Makefile with common tasks:
  • make dev - Start dev environment
  • make test - Run tests
  • make lint - Run linters
  • make generate - Generate code
  • make docker-build - Build Docker image
  • make migrate - Run migrations
• Add development scripts:
  • scripts/dev.sh - Start all services
  • scripts/test.sh - Run test suite
  • scripts/seed.sh - Seed test data
• Create .env.example with all config variables

Acceptance Criteria

• Docker images build and run successfully
• Docker Compose works for development
• Deployment guides are tested
• New developers can set up environment in <30 minutes

Files to Create/Modify

• Dockerfile - Multi-stage build
• docker-compose.yml - Development compose
• docker-compose.prod.yml - Production compose
• docs/deployment/ - Deployment guides
• Makefile - Enhanced with more commands
• scripts/ - Development scripts
