# Build and Usage Instructions
|
|
# ===================================================================
|
|
# Build with default parameters:
|
|
# docker build -t meldestelle/web-app:latest -f dockerfiles/clients/web-app/Dockerfile .
|
|
#
|
|
# Build with custom parameters:
|
|
# docker build -t meldestelle/web-app:latest \
|
|
# --build-arg NODE_VERSION=20.11.0 \
|
|
# --build-arg CLIENT_PATH=client/web-app \
|
|
# --build-arg CLIENT_MODULE=client:web-app \
|
|
# -f dockerfiles/clients/web-app/Dockerfile .
|
|
#
|
|
# Run standalone:
|
|
# docker run -p 3001:80 --name web-app meldestelle/web-app:latest
|
|
#
|
|
# Run with API backend:
|
|
# docker run -p 3001:80 --link api-gateway:api-gateway --name web-app meldestelle/web-app:latest
|
|
#
|
|
# Access application:
|
|
# http://localhost:3001
|
|
# http://localhost:3001/health (health check)
|
|
#
|
|
# Development with hot-reload (use docker-compose.override.yml instead)
|
|
#
|
|
# Optimization improvements:
|
|
# - Added Node.js v20.11.0 for optimal Kotlin/JS compatibility
|
|
# - Parametrized build arguments for better maintainability
|
|
# - Enhanced npm and Node.js environment variables
|
|
# - Improved error handling with --stacktrace and --debug flags
|
|
# - npm cache management for better performance
