Database Operations

PostgreSQL Access

# Connect to database
docker compose exec postgres psql postgresql://app_user:pass12345@127.0.0.1:5432/app_db

# Connect to PostgreSQL directly
docker compose exec postgres psql -U $POSTGRES_USER -d $POSTGRES_DB

# Run SQL file
docker compose exec -T postgres psql -U $POSTGRES_USER -d $POSTGRES_DB -f /docker-entrypoint-initdb.d/your_script.sql

# Create database backup
docker compose exec -T postgres pg_dump -U $POSTGRES_USER $POSTGRES_DB > backup.sql

Redis Operations

# Connect to Redis CLI
docker compose exec redis redis-cli -a $REDIS_PASSWORD

# Monitor Redis in real-time
docker compose exec redis redis-cli -a $REDIS_PASSWORD monitor

# Redis info and stats
docker compose exec redis redis-cli -a $REDIS_PASSWORD info

Monitoring Tools

Access Monitoring Interfaces

# PgAdmin (http://localhost:8080)
# Redis Commander (http://localhost:8081)

# Start only monitoring services
docker compose --profile monitoring up pgadmin redis-commander -d

Maintenance and Cleanup

Data Management

# Backup volumes
tar -czf backup_$(date +%Y%m%d).tar.gz data/

# Restore volumes
tar -xzf backup_20231201.tar.gz

# Clean up unused volumes
docker volume prune

System Cleanup

# Remove all containers, networks, and images
docker compose down --rmi all --volumes

# Remove unused Docker objects
docker system prune

# Remove specific volumes
docker volume rm $(docker compose config --volumes)

Development and Debugging

Debug Commands

# Shell access to containers
docker compose exec postgres bash
docker compose exec redis sh

# View specific service logs with timestamps
docker compose logs -f --timestamps postgres

# Check service health
docker compose exec postgres pg_isready -U $POSTGRES_USER

# Test Redis connection
docker compose exec redis redis-cli -a $REDIS_PASSWORD ping

Configuration Validation

# Validate compose file
docker compose config

# Dry run to see what would be created
docker compose up --dry-run

# List all services
docker compose config --services

Service-Specific Management

PostgreSQL Maintenance

# Check PostgreSQL configuration
docker compose exec postgres cat /bitnami/postgresql/conf/postgresql.conf

# Restart PostgreSQL with new config
docker compose restart postgres

# Check connection count
docker compose exec postgres psql -U $POSTGRES_USER -d $POSTGRES_DB -c "SELECT count(*) FROM pg_stat_activity;"

Redis Maintenance

# Flush Redis database
docker compose exec redis redis-cli -a $REDIS_PASSWORD FLUSHALL

# Save Redis data to disk
docker compose exec redis redis-cli -a $REDIS_PASSWORD SAVE

# Get Redis memory info
docker compose exec redis redis-cli -a $REDIS_PASSWORD INFO MEMORY

Quick Reference - Common Workflows

Development Startup

# 1. Start all services
docker compose up -d

# 2. Start monitoring tools
docker compose --profile monitoring up -d

# 3. Verify services
docker compose ps

Production-like Setup

# Start core services only (no monitoring)
docker compose up -d postgres redis

# Check health status
docker compose ps

Emergency Recovery

# Stop everything
docker compose down

# Restart with clean state (preserves data)
docker compose up --profile monitoring -d

# If having issues, rebuild
docker compose up -d --build
