Fix Zitadel deployment by removing FirstInstance variables

Browse source 
- Remove all ZITADEL_FIRSTINSTANCE_* environment variables
- Fixes migration error: duplicate key constraint violation
- Root cause: Bug in Zitadel v2.63.7 FirstInstance migration
- Workaround: Complete initial setup via web UI
- Upstream issue: https://github.com/zitadel/zitadel/issues/8791

Changes:
- Clean up obsolete documentation (OIDC_AUTOMATION.md, SETUP_GUIDE.md, COLLABORA_SETUP.md)
- Add PROJECT_REFERENCE.md for essential configuration info
- Add force recreate functionality with clean database volumes
- Update bootstrap instructions for web UI setup
- Document one-time manual setup requirement for OIDC automation

Zitadel now deploys successfully and is accessible at:
https://zitadel.test.vrije.cloud

```
## Essential Configuration
### SOPS Age Key
**Location**: `infrastructure/keys/age-key.txt`
**Usage**: Always set before running Ansible:
```bash
export SOPS_AGE_KEY_FILE="../keys/age-key.txt"
```
### Hetzner Cloud Token
**Usage**: Required for dynamic inventory:
```bash
export HCLOUD_TOKEN="MlURmliUzLcGyzCWXWWsZt3DeWxKcQH9ZMGiaaNrFM3VcgnASlEWKhhxLHdWAl0J"
```
### Ansible Paths
**Working Directory**: `infrastructure/ansible/`
**Inventory**: `hcloud.yml` (dynamic, pulls from Hetzner Cloud API)
**Python**: `~/.local/bin/ansible-playbook` (user-local installation)
## Current Deployment
### Client: test
- **Hostname**: test (from Hetzner Cloud)
- **Zitadel**: https://zitadel.test.vrije.cloud
- **Nextcloud**: https://nextcloud.test.vrije.cloud
- **Secrets**: `secrets/clients/test.sops.yaml`
## Common Operations
### Deploy Applications
```bash
cd infrastructure/ansible
export HCLOUD_TOKEN="MlURmliUzLcGyzCWXWWsZt3DeWxKcQH9ZMGiaaNrFM3VcgnASlEWKhhxLHdWAl0J"
export SOPS_AGE_KEY_FILE="../keys/age-key.txt"
# Deploy everything to test client
~/.local/bin/ansible-playbook -i hcloud.yml playbooks/deploy.yml --limit test
# Force recreate Zitadel (clean database)
~/.local/bin/ansible-playbook -i hcloud.yml playbooks/deploy.yml --limit test \
--extra-vars "zitadel_force_recreate=true"
```
### Check Service Status
```bash
# List inventory hosts
export HCLOUD_TOKEN="..."
~/.local/bin/ansible-inventory -i hcloud.yml --list
# Run ad-hoc commands
~/.local/bin/ansible test -i hcloud.yml -m shell -a "docker ps"
~/.local/bin/ansible test -i hcloud.yml -m shell -a "docker logs zitadel 2>&1 | tail -50"
```
### Edit Secrets
```bash
cd infrastructure
export SOPS_AGE_KEY_FILE="keys/age-key.txt"
# Edit client secrets
sops secrets/clients/test.sops.yaml
# View decrypted secrets
sops --decrypt secrets/clients/test.sops.yaml
```
## Architecture Notes
### Service Stack
- **Traefik**: Reverse proxy with automatic Let's Encrypt certificates
- **Zitadel v2.63.7**: Identity provider (OIDC/OAuth2)
- **PostgreSQL 16**: Database for Zitadel
- **Nextcloud 30.0.17**: File sync and collaboration
- **Redis**: Caching for Nextcloud
### Docker Networks
- `traefik`: External network for all web-accessible services
- `zitadel-internal`: Internal network for Zitadel ↔ PostgreSQL
- `nextcloud-internal`: Internal network for Nextcloud ↔ Redis
### Volumes
- `zitadel_zitadel-db-data`: PostgreSQL data
- `zitadel_zitadel-machinekey`: JWT keys for service accounts
- `nextcloud_nextcloud-data`: Nextcloud files and database
## Known Issues
### Zitadel FirstInstance Configuration Bug
**Issue**: ALL `ZITADEL_FIRSTINSTANCE_*` environment variables cause migration errors in v2.63.7:
```
ERROR: duplicate key value violates unique constraint "unique_constraints_pkey"
Errors.Instance.Domain.AlreadyExists
```
**Root Cause**: Bug in Zitadel v2.63.7 FirstInstance migration logic
**Workaround**: Remove all FirstInstance variables; complete initial setup via web UI
**Upstream Issue**: https://github.com/zitadel/zitadel/issues/8791
**Status**: Waiting for upstream fix
### OIDC Automation
**Issue**: Automatic OIDC app provisioning requires manual one-time setup
**Workaround**:
1. Complete Zitadel web UI setup wizard (first access)
2. Create service user with JWT key via web UI
3. Store JWT key in secrets for automated provisioning
**Status**: Manual one-time setup required per Zitadel instance
## Service Credentials
### Zitadel Admin
- **URL**: https://zitadel.test.vrije.cloud
- **Setup**: Complete wizard on first visit (no predefined credentials)
### Nextcloud Admin
- **URL**: https://nextcloud.test.vrije.cloud
- **Username**: admin
- **Password**: In `secrets/clients/test.sops.yaml` → `nextcloud_admin_password`

# Collabora Office Setup
## Password Configuration
Add the following to `secrets/clients/test.sops.yaml`:
```bash
cd infrastructure
export SOPS_AGE_KEY_FILE="$PWD/keys/age-key.txt"
sops secrets/clients/test.sops.yaml
```
Then add this line:
```yaml
collabora_admin_password: <generate-strong-password-here>
```
Replace `<generate-strong-password-here>` with a strong password generated using:
```bash
openssl rand -base64 32 | tr -d "=+/" | cut -c1-32
```
Save and exit. SOPS will automatically re-encrypt the file.
## Features Added
### 1. Collabora Office Container
- Online document editing (Word, Excel, PowerPoint)
- Integrated with Nextcloud via WOPI protocol
- Accessible at: https://office.{client}.vrije.cloud
- Resource limits: 1GB RAM, 2 CPUs
### 2. Separate Cron Container
- Dedicated container for background jobs
- Uses same image as Nextcloud
- Shares data volume
- Runs `/cron.sh` entrypoint
### 3. Two-Factor Authentication
Apps installed:
- `twofactor_totp` - TOTP authenticator apps (Google Authenticator, Authy, etc.)
- `twofactor_admin` - Admin enforcement
- `twofactor_backupcodes` - Backup codes for account recovery
Configuration:
- 2FA enforced for all users
- Users must set up 2FA on first login (after SSO)
### 4. Dual-Cache Strategy
- **APCu**: Local in-memory cache (fast, single-server)
- **Redis**: Distributed cache and file locking (shared across containers)
Configuration:
```php
'memcache.local' => '\\OC\\Memcache\\APCu',
'memcache.distributed' => '\\OC\\Memcache\\Redis',
'memcache.locking' => '\\OC\\Memcache\\Redis',
```
### 5. Maintenance Window
- Set to 2:00 AM for automatic maintenance tasks
- Minimizes user disruption
## Deployment
After adding the Collabora password, redeploy:
```bash
cd infrastructure/ansible
export SOPS_AGE_KEY_FILE="../keys/age-key.txt"
export HCLOUD_TOKEN="..."
ansible-playbook -i hcloud.yml playbooks/deploy.yml
```
## Collabora Configuration in Nextcloud
The automation configures:
- WOPI URL: `https://office.{client}.vrije.cloud`
- WOPI Allowlist: Docker internal networks (172.18.0.0/16, 172.21.0.0/16)
- SSL termination: Handled by Traefik
## Testing
### 1. Test Collabora Office
1. Login to Nextcloud
2. Create a new document (File → New → Document)
3. Should open Collabora Online editor
4. If it doesn't load, check:
- Collabora container is running: `docker ps | grep collabora`
- WOPI URL is configured: `docker exec -u www-data nextcloud php occ config:app:get richdocuments wopi_url`
- Network connectivity between containers
### 2. Test Two-Factor Authentication
1. Login to Nextcloud (via SSO or direct)
2. Should be prompted to set up 2FA
3. Use authenticator app to scan QR code
4. Enter TOTP code to verify
5. Save backup codes
### 3. Test Cron Jobs
Check if cron is running:
```bash
docker logs nextcloud-cron
```
Should see periodic job execution logs.
### 4. Test Caching
Check configuration:
```bash
docker exec -u www-data nextcloud php occ config:list system
```
Should show APCu and Redis configuration.
## Troubleshooting
### Collabora Not Loading
**Symptom**: Blank page or "Failed to load" when creating documents
**Solutions**:
1. Check Collabora is running: `docker ps | grep collabora`
2. Check Collabora logs: `docker logs collabora`
3. Verify WOPI URL: Should be `https://office.{client}.vrije.cloud`
4. Check network allowlist includes Nextcloud container IP
5. Test Collabora directly: Visit `https://office.{client}.vrije.cloud` (should show Collabora page)
### 2FA Not Enforcing
**Symptom**: Users can skip 2FA setup
**Solution**:
```bash
docker exec -u www-data nextcloud php occ config:system:set twofactor_enforced --value="true" --type=boolean
```
### Cron Not Running
**Symptom**: Background jobs not executing
**Solutions**:
1. Check container: `docker ps | grep nextcloud-cron`
2. Check logs: `docker logs nextcloud-cron`
3. Restart: `docker restart nextcloud-cron`
### Cache Not Working
**Symptom**: Slow performance
**Solutions**:
1. Verify APCu is installed: `docker exec nextcloud php -m | grep apcu`
2. Verify Redis connection: `docker exec nextcloud-redis redis-cli ping`
3. Check config: `docker exec -u www-data nextcloud php occ config:list system`
## Security Considerations
### Collabora Admin Password
The Collabora admin interface is protected by username/password:
- Username: `admin`
- Password: Stored in secrets (SOPS encrypted)
- Access: https://office.{client}.vrije.cloud/browser/dist/admin/admin.html
**Recommendation**: Change password after first deployment.
### 2FA Backup Codes
Users receive backup codes when setting up 2FA. These should be:
- Stored securely (password manager or printed)
- Used only if TOTP device is lost
- Regenerated after use
### Network Isolation
Collabora and Nextcloud communicate over Docker internal network:
- Not exposed to public internet
- WOPI protocol secured by allowlist
- SSL termination at Traefik edge
## Performance Tuning
### Collabora Resource Limits
Default: 1GB RAM, 2 CPUs
Adjust in `docker-compose.nextcloud.yml.j2`:
```yaml
deploy:
resources:
limits:
memory: 2g # Increase for heavy usage
cpus: '4' # More CPUs for concurrent users
```
### Nextcloud PHP Memory
Default: 512M
Increase in `defaults/main.yml`:
```yaml
nextcloud_php_memory_limit: "1G"
```
### Redis Memory
Redis uses system memory dynamically. Monitor with:
```bash
docker exec nextcloud-redis redis-cli INFO memory
```

# OIDC/SSO Automation
This document explains the fully automated OIDC/SSO setup between Zitadel and Nextcloud.
## Overview
The infrastructure now supports **fully automated** OIDC application provisioning, eliminating manual configuration steps. This makes the system scalable to dozens or hundreds of servers.
## How It Works
### 1. Automated OIDC App Creation
When deploying a new client, the Ansible playbook automatically:
1. **Authenticates with Zitadel** using admin credentials
2. **Creates OIDC application** via Zitadel Management API
3. **Retrieves client credentials** (client ID and secret)
4. **Configures Nextcloud** with the OIDC provider
### 2. Zero Manual Steps
The entire SSO setup happens automatically during deployment:
```bash
ansible-playbook -i hcloud.yml playbooks/deploy.yml
```
No need to:
- Login to Zitadel console
- Manually create OIDC apps
- Copy/paste client credentials
- Configure Nextcloud manually
### 3. Scalability
This automation makes it trivial to deploy **dozens of servers**:
```yaml
# terraform.tfvars
clients = {
client1 = { ... }
client2 = { ... }
client3 = { ... }
# Add as many as needed!
}
```
Each client gets:
- Its own Zitadel instance
- Its own Nextcloud instance
- Automatic OIDC configuration
- Unique credentials
## Technical Implementation
### Components
1. **`get_admin_token.sh`**: Authenticates with Zitadel using admin credentials
2. **`create_oidc_app.py`**: Creates OIDC app via Zitadel Management API
3. **`oidc-apps.yml`**: Ansible task orchestrating the automation
4. **`nextcloud/oidc.yml`**: Configures Nextcloud with OIDC provider
### Authentication Flow
```
1. Ansible → get_admin_token.sh → Zitadel OAuth2
2. Receives → JWT access token
3. Ansible → create_oidc_app.py → Zitadel Management API
4. Creates → OIDC application
5. Returns → Client ID + Client Secret
6. Ansible → Nextcloud occ command
7. Configures → OIDC provider
```
### API Endpoints Used
- **Token**: `POST https://{domain}/oauth/v2/token`
- **Projects**: `POST https://{domain}/management/v1/projects/_search`
- **Create App**: `POST https://{domain}/management/v1/projects/{id}/apps/oidc`
### Security Considerations
- Admin credentials are stored in **encrypted SOPS secrets**
- Access tokens are **ephemeral** (generated per-deployment)
- Client secrets are **never logged** (no_log: true)
- API calls use **HTTPS only**
## Configuration Options
### Zitadel OIDC App Settings
The automation creates apps with these settings:
```yaml
- Response Type: Authorization Code
- Grant Types: Authorization Code, Refresh Token
- App Type: Web Application
- Auth Method: Client Secret Basic
- Token Type: JWT
- Role Assertions: Enabled
- UserInfo Assertions: Enabled
```
### Nextcloud OIDC Provider
Configured with:
```yaml
- Provider Name: Zitadel
- Client ID: <auto-generated>
- Client Secret: <auto-generated>
- Discovery URI: https://{domain}/.well-known/openid-configuration
```
## Testing
After deployment, verify SSO works:
1. Visit: `https://nextcloud.{client}.vrije.cloud`
2. Click "Login with SSO" or "Zitadel"
3. Redirected to Zitadel login
4. Enter Zitadel credentials
5. Redirected back to Nextcloud (logged in)
## Troubleshooting
### OIDC App Not Created
Check Ansible output for errors in:
- `Get admin access token for API calls`
- `Create OIDC application for Nextcloud`
Common issues:
- Admin password incorrect
- Zitadel API not accessible
- Network connectivity issues
### Nextcloud OIDC Not Configured
Check if credentials were passed:
- `nextcloud_oidc_client_id` should be defined
- `nextcloud_oidc_client_secret` should be defined
Verify in Nextcloud:
```bash
docker exec -u www-data nextcloud php occ user_oidc:provider
```
### SSO Login Fails
Check redirect URI matches exactly:
```
https://nextcloud.{client}.vrije.cloud/apps/user_oidc/code
```
Check Zitadel application settings:
- Redirect URIs configured correctly
- Grant types include Authorization Code
- Application is active (not disabled)
## Future Enhancements
Potential improvements:
1. **Service Account**: Use dedicated service account instead of admin
2. **Token Caching**: Cache access tokens to reduce API calls
3. **Multi-App Support**: Automate Collabora, OnlyOffice, etc.
4. **Role Mapping**: Sync Zitadel roles to Nextcloud groups
5. **User Provisioning**: Auto-create users on first SSO login
