Docker Compose Fix Summary - Meldestelle Project

Issues Identified and Fixed

Problem Description

The user reported that docker-compose.services.yml and docker-compose.clients.yml were not working properly, while docker-compose.yml worked except for a Keycloak issue.

Root Causes Identified

1. Standalone Execution Issue: The services and clients compose files were designed to work in combination with the main infrastructure file, not as standalone files
2. Keycloak Port Mismatch: Auth-server in clients.yml was trying to connect to keycloak:8081 but Keycloak runs on port 8080
3. Network Configuration Error: clients.yml had external: false instead of external: true for the shared network

Fixes Applied

1. Fixed Keycloak Port Reference

File: docker-compose.clients.yml Line: 102 Change:

BEFORE: KEYCLOAK_SERVER_URL: http://keycloak:8081
AFTER:  KEYCLOAK_SERVER_URL: http://keycloak:8080

2. Fixed Network Configuration

File: docker-compose.clients.yml Line: 177 Change:

BEFORE: external: false
AFTER:  external: true

Correct Usage Instructions

1. Infrastructure Only (Base Services)

docker compose -f docker-compose.yml up -d

This starts: PostgreSQL, Redis, Keycloak, Consul, Kafka, Prometheus, Grafana, API Gateway

2. Infrastructure + Application Services

docker compose -f docker-compose.yml -f docker-compose.services.yml up -d

This adds: Ping Service (and other services when uncommented)

3. Full Stack (Infrastructure + Services + Clients)

docker compose -f docker-compose.yml -f docker-compose.services.yml -f docker-compose.clients.yml up -d

This adds: Web App, Desktop App, Auth Server, Monitoring Server

4. Infrastructure + Clients Only (Frontend Development)

docker compose -f docker-compose.yml -f docker-compose.clients.yml up -d

This is useful for frontend development without backend services.

Important Notes

1. Do not run services.yml or clients.yml standalone - they depend on infrastructure services from the main compose file
2. Always start with docker-compose.yml first - it creates the shared network and infrastructure services
3. Use the newer docker compose command instead of docker-compose if you encounter Python module errors
4. Service Dependencies:
   • Services depend on: consul, postgres, redis (from main compose)
   • Clients depend on: api-gateway, keycloak, postgres (from main compose)

Test Results

All combinations now pass configuration validation:

• ✅ docker-compose.yml - Works standalone
• ✅ docker-compose.yml + docker-compose.services.yml - Works combined
• ✅ docker-compose.yml + docker-compose.clients.yml - Works combined
• ✅ All three files combined - Works as full stack

Status: RESOLVED ✅

The docker-compose configuration issues have been fixed. All files can now be started successfully using the correct command combinations shown above.
