# 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)
|
||||
```bash
|
||||
docker compose -f docker-compose.yml up -d
|
||||
```
|
||||
This starts: PostgreSQL, Redis, Keycloak, Consul, Kafka, Prometheus, Grafana, API Gateway
|
||||
|
||||
### 2. Infrastructure + Application Services
|
||||
```bash
|
||||
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)
|
||||
```bash
|
||||
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)
|
||||
```bash
|
||||
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.
