How to fix no such service: myservice in Docker

services:
  web:              # <-- This is the service name
    container_name: myapp  # <-- This is NOT the service name
    image: nginx

  database:         # <-- Another service name
    image: postgres

# CORRECT - uses service name
docker-compose up web

# WRONG - uses container name
docker-compose up myapp

# Show current directory
pwd

# Check if docker-compose.yml exists here
ls -la docker-compose.yml

# If not found, navigate to the correct directory
cd /path/to/your/project

# For custom-named files
docker-compose -f docker-compose.dev.yml up myservice
docker-compose -f docker-compose.dev.yml logs myservice

# For multiple compose files, specify all of them
docker-compose -f docker-compose.yml -f docker-compose.override.yml up myservice

# List all service names
docker-compose config --services

# Or view the full config
docker-compose config

services:
  WebApp:    # Case matters!
    image: nginx

# WRONG - wrong case
docker-compose up webapp

# CORRECT - matches exactly
docker-compose up WebApp

# Start all services defined in docker-compose.yml
docker-compose up -d

# View logs for all services
docker-compose logs

# Stop all services
docker-compose down
