Docker Compose with Data Persistence Lab

Orchestrate the complete TaskFlow stack with Docker Compose: frontend, backend, PostgreSQL, and Redis. Implement persistent volumes and verify data survives container restarts.

Lab Overview

Build a production-ready local development environment for TaskFlow using Docker Compose. You'll create a docker-compose.yml file that orchestrates all four services (frontend, backend, database, cache) with proper networking, health checks, and data persistence.

You'll configure named volumes for PostgreSQL and Redis to ensure data survives container restarts, create backup/restore scripts, and modify the Vue.js frontend to display environment information using ConfigMaps.

By the end of this lab, you'll understand:

  • Docker Compose service orchestration
  • Named volumes for data persistence
  • Service dependencies and health checks
  • Docker networking between containers
  • Backup and restore strategies for volumes
  • Environment configuration in multi-service applications
  • Verifying data persistence across container lifecycles

What You'll Learn

Write a Docker Compose file that defines multi-container application services

Add PostgreSQL and Redis services with named volumes for data persistence

Configure service dependencies and health check conditions using depends_on

Verify that data persists across container restarts using Docker volumes

Manage a complete development environment with docker compose up and down
