|
# EXAMPLE: Load Balancing with Multiple Container Replicas
|
|
# ==============================================================================
|
|
#
|
|
# WHAT THIS DEMONSTRATES:
|
|
# - Multiple container replicas behind a single domain
|
|
# - Round-robin load balancing across replicas
|
|
# - Domain redirect functionality
|
|
# - Custom port configuration
|
|
#
|
|
# REQUIREMENTS (run these first):
|
|
# ```bash
|
|
# # No special requirements - this example runs on localhost:19901
|
|
# ```
|
|
#
|
|
# HOW TO START:
|
|
# ```bash
|
|
# docker compose -f docker-compose-multi-containers.yml up -d
|
|
# ```
|
|
#
|
|
# HOW TO VERIFY IT'S WORKING:
|
|
# ```bash
|
|
# # Test load balancing - hostname should alternate between containers
|
|
# curl -H "Host: www.helloworld.com" localhost:19901
|
|
# # Expected: Container ID (e.g., f6d8d45b7411)
|
|
# curl -H "Host: www.helloworld.com" localhost:19901
|
|
# # Expected: Different container ID (e.g., 59b213cb8592)
|
|
#
|
|
# # Test domain redirect
|
|
# curl -I -H "Host: google.helloworld.com" localhost:19901
|
|
# # Expected: HTTP/1.1 301 Moved Permanently, Location: www.google.com/

# # URL: http://localhost:1936
|
|
# # Username: admin
|
|
# # Password: password
|
|
# # You should see 2 backend servers
|
|
# ```
|
|
#
|
|
# CLEAN UP:
|
|
# ```bash
|
|
# docker compose -f docker-compose-multi-containers.yml down
|
|
# ```
