# Authentik Forward Authentication Deployment Summary
## Overview
Successfully deployed Authentik forward authentication to all NPM-managed domains. All protected sites now require SSO authentication via Authentik before access is granted.
## Deployment Date
2025-11-16
## Architecture
### Components
1. **Authentik Server** (`authentik-server`)
- Port: 9000
- Container: `authentik-server`
- Purpose: Main authentication server
2. **Authentik Proxy Outpost** (`authentik-proxy-outpost`)
- Port: 9001 (HTTP), 9300 (Metrics)
- Container: `authentik-proxy-outpost`
- Purpose: Forward authentication endpoint for NPM
- Network: host mode (to match NPM)
- Image: `ghcr.io/goauthentik/proxy:latest`
3. **Nginx Proxy Manager** (`nginx-proxy-manager`)
- Ports: 80, 81, 443
- Purpose: Reverse proxy with SSL termination
- Forward auth endpoint: `http://192.168.86.149:9001/outpost.goauthentik.io/auth/nginx`
### Authentication Flow
```
1. User → https://home.schweitz.net
2. NPM → auth_request to http://192.168.86.149:9001/outpost.goauthentik.io/auth/nginx
3. Outpost → validates session with Authentik Server (port 9000)
4. If not authenticated:
a. NPM → redirects to /outpost.goauthentik.io/start?rd=https://home.schweitz.net/
b. Outpost → redirects to https://auth.schweitz.net/if/flow/...
c. User → logs in via Google OAuth
d. Authentik → sets session cookie
e. Redirect → back to https://home.schweitz.net/
5. If authenticated:
a. Request passes through with user headers
```
## Protected Domains
All NPM proxy hosts now require authentication:
1. **192.168.86.149** - Direct IP access
2. **amp.schweitz.net** - AMP Server
3. **cloud.schweitz.net** - Nextcloud
4. **code.schweitz.net** - VS Code Server
5. **git.schweitz.net** - Gitea
6. **home.schweitz.net** - Home Assistant/Dashboard
7. **media.schweitz.net** - Media Server
8. **tatlock.schweitz.net** - Tatlock Services
9. **tower-of-joy** - Tower of Joy Services
### Excluded Domains
- **auth.schweitz.net** - Authentik itself (cannot protect the auth provider)
## Configuration Details
### Authentik Proxy Provider
- **Name**: `npm-forward-auth-provider`
- **ID**: 2
- **Mode**: `forward_single`
- **External Host**: `https://auth.schweitz.net`
- **Token Validity**: 480 minutes (8 hours)
- **Session Duration**: 480 minutes (8 hours)
- **Rolling Expiration**: Active (sessions extend on use)
### Authentik Outpost

- **Container**: `authentik-proxy-outpost`
- **Listen**: `0.0.0.0:9001` (HTTP), `0.0.0.0:9300` (metrics)
### NPM Configuration
Each protected proxy host has this advanced nginx configuration:
```nginx
# Authentik Forward Authentication
# Send authentication requests to Authentik
auth_request /outpost.goauthentik.io/auth/nginx;
# Preserve authentication cookies
auth_request_set $auth_cookie $upstream_http_set_cookie;
add_header Set-Cookie $auth_cookie;
# Get user information from Authentik
auth_request_set $authentik_username $upstream_http_x_authentik_username;
auth_request_set $authentik_groups $upstream_http_x_authentik_groups;
auth_request_set $authentik_email $upstream_http_x_authentik_email;
auth_request_set $authentik_name $upstream_http_x_authentik_name;
auth_request_set $authentik_uid $upstream_http_x_authentik_uid;
# Pass user info to backend
proxy_set_header X-authentik-username $authentik_username;
proxy_set_header X-authentik-groups $authentik_groups;
proxy_set_header X-authentik-email $authentik_email;
proxy_set_header X-authentik-name $authentik_name;
proxy_set_header X-authentik-uid $authentik_uid;
# On authentication failure, redirect to Authentik login
error_page 401 = @authentik_proxy_signin;
location @authentik_proxy_signin {
internal;
add_header Set-Cookie $auth_cookie;
return 302 /outpost.goauthentik.io/start?rd=$scheme://$http_host$request_uri;
}
# Authentik authentication endpoint
location /outpost.goauthentik.io {
proxy_pass http://192.168.86.149:9001/outpost.goauthentik.io;
proxy_set_header X-Original-URL $scheme://$http_host$request_uri;
proxy_pass_request_body off;
proxy_set_header Content-Length "";
proxy_set_header Host $host;
}
```
## Deployment Steps Taken
### 1. Created Proxy Provider
```bash
docker exec core-api /venv/bin/python /app/setup_authentik_forward_auth.py
```
- Created `npm-forward-auth-provider` proxy provider (ID: 2)
- Created `NPM Forward Auth` application (slug: `npm-forward-auth`)
- Updated embedded outpost to include provider
### 2. Enabled Forward Auth on NPM Hosts
```bash
docker exec core-api /venv/bin/python /app/enable_npm_forward_auth.py
```
- Added forward auth configuration to all 9 NPM proxy hosts
- Initially pointed to `http://192.168.86.149:9000` (incorrect)
### 3. Created Proxy Outpost
```bash
python3 -c "..." # Created outpost via Authentik API
```
- Created `npm-forward-auth-outpost` (ID: `5fbba1f4-e50f-4d3f-94e8-8d9f30bf7a51`)
- Authentik auto-created container via Docker service connection
- Retrieved token from auto-created container environment variables
### 4. Deployed Proxy Outpost Container
```bash
docker run -d \
--name authentik-proxy-outpost \
--restart unless-stopped \
--network host \
-e AUTHENTIK_HOST=http://192.168.86.149:9000 \
-e AUTHENTIK_TOKEN=aVJXnn3I44NhTYRYxGtbP3kJLEKQrTEMwu9IPVrhzN3NZV4vakgztcEf2L44 \
-e AUTHENTIK_LISTEN__HTTP=0.0.0.0:9001 \
-e AUTHENTIK_LISTEN__METRICS=0.0.0.0:9300 \
ghcr.io/goauthentik/proxy:latest
```
### 5. Updated NPM Hosts to Port 9001
```bash
docker exec core-api /venv/bin/python /app/fix_port_to_9001.py
```
- Updated all 9 hosts to point to `http://192.168.86.149:9001` instead of port 9000
## Verification
### Testing Forward Auth
```bash
# Test ping endpoint
curl http://192.168.86.149:9001/outpost.goauthentik.io/ping
# Expected: 204 No Content
# Test unauthenticated request
curl -I http://home.schweitz.net
# Expected: 302 redirect to /outpost.goauthentik.io/start?rd=...
```
### Logs
```bash
# Outpost logs
docker logs authentik-proxy-outpost
# Authentik server logs
docker logs authentik-server
# NPM logs
docker logs nginx-proxy-manager
```
## Token & Session Management
### Token Validity
- **Initial validity**: 480 minutes (8 hours)
- **Rolling expiration**: Token stays active on use
- **Idle timeout**: 8 hours after last activity
- **Explicit logout**: Token invalidated immediately at https://auth.schweitz.net/if/user/#/settings
### Session Behavior
- **Single login** protects all domains under `*.schweitz.net`
- **Cookie domain**: Shared across all sites (set by individual domain)
- **Persistent**: Survives browser restarts until expiration/logout
- **Secure**: HTTPS-only, HttpOnly flag set
## User Management
### Adding Users
1. Go to https://auth.schweitz.net/if/admin/
2. Navigate to **Directory** → **Users**
3. Click **Create** → **Create and enroll user**
4. Enter user details
5. Send enrollment invite
### Current Access Control
**All authenticated users** can access all protected sites. To restrict:
1. Go to https://auth.schweitz.net/if/admin/#/core/applications
2. Select **NPM Forward Auth** application
3. Go to **Policy / Group / User Bindings**
4. Add specific users or groups
## Troubleshooting
### Check Outpost Status
```bash
docker ps | grep authentik-proxy-outpost
docker logs authentik-proxy-outpost --tail 50
```
### Check Authentik Server
```bash
docker logs authentik-server --tail 50 | grep -i outpost
```
### Test Endpoints
```bash
# Ping (should return 204)
curl -I http://192.168.86.149:9001/outpost.goauthentik.io/ping
# Auth endpoint (needs proper headers from nginx)
curl -I http://home.schweitz.net
```
### Common Issues
1. **502 Bad Gateway**: Outpost not running or not reachable
- Check: `docker ps | grep authentik-proxy-outpost`
- Fix: Restart outpost container
2. **Redirect Loop**: Misconfigured nginx or outpost
- Check: NPM advanced config points to port 9001
- Check: Outpost logs for errors
3. **Session Expires Too Quickly**: Token validity too short
- Check: Provider token_validity setting (should be 480 minutes)
## Automation Scripts
### Enable Forward Auth on New Sites
```python
from src.clients.npm_client import get_npm_client
npm = get_npm_client()
proxy = await npm.create_proxy_host(
domain_names=["newsite.schweitz.net"],
forward_host="backend-container",
forward_port=8080,
ssl_enabled=True
)
await npm.enable_authentik_forward_auth(proxy["id"])
```
### Bulk Operations
```bash
# Enable on all hosts
docker exec core-api /venv/bin/python /app/enable_npm_forward_auth.py
# Update to port 9001
docker exec core-api /venv/bin/python /app/fix_port_to_9001.py
```
## Security Considerations
1. ✓ **HTTPS Required**: All sites use SSL termination at NPM
2. ✓ **Secure Cookies**: HttpOnly and Secure flags prevent XSS/MITM
3. ✓ **Token Rotation**: Tokens extend on activity for security
4. ✓ **Audit Logging**: Authentik logs all authentication events
5. ⚠ **MFA**: Not yet enabled (future enhancement)
## Monitoring
### Health Checks
```bash
# Authentik server
curl http://192.168.86.149:9000/-/health/live/
# Proxy outpost
curl http://192.168.86.149:9001/outpost.goauthentik.io/ping
# Metrics
curl http://192.168.86.149:9300/metrics
```
### Authentik Admin Dashboard
- **URL**: https://auth.schweitz.net/if/admin/
- **Events**: System → Events (view login attempts, failures)
- **Active Sessions**: System → Tokens
- **Outpost Status**: System → Outposts
## Future Enhancements
1. **Multi-Factor Authentication**: Enable TOTP/SMS for high-security sites
2. **Per-Site Access Control**: Different user groups for different domains
3. **Rate Limiting**: Prevent brute force attacks
4. **IP Whitelisting**: Allow certain IPs without auth
5. **API Key Support**: Service-to-service authentication
6. **Integration with Core API**: Expose auth status via REST API

## Notes
- The embedded Authentik outpost (ID: `fbbefe20-b2e1-4706-8533-7bfece51989c`) is for Authentik's own web UI, not for external forward auth
- Forward auth requires a separate proxy outpost container listening on its own port (9001)
- The outpost automatically created by Authentik via Docker service connection had the wrong port configuration
- We manually deployed the outpost with correct settings using `docker run`
- NPM uses host network mode, so the outpost must also use host mode or be accessible via host IP:port
- Token keys are only visible once during creation in the Authentik UI; we retrieved it from the auto-created container's environment variables
## Completion Status
✅ **COMPLETE** - All protected sites now require Authentik authentication

# Authentik Forward Authentication Configuration
## Overview
All NPM-managed domains now use Authentik for centralized Single Sign-On (SSO) authentication. When users access any protected site, they are automatically redirected to Authentik for login, then returned to their original destination.
## Authentication Flow
1. **User accesses protected site** (e.g., https://portainer.schweitz.net)
2. **NPM checks authentication** via Authentik forward auth
3. **If not authenticated**: Redirect to https://auth.schweitz.net/outpost.goauthentik.io/start
4. **User logs in** with Google (via Authentik)
5. **Authentik sets session cookie** (8-hour validity)
6. **Redirect back** to originally requested URL
7. **Subsequent requests**: Automatically authenticated (no login required)
## Token & Session Configuration
### Token Validity
- **Initial validity**: 8 hours (480 minutes)
- **Activity-based extension**: Token stays active on use (rolling expiration)
- **Idle timeout**: 8 hours after last activity
- **Explicit logout**: Token invalidated immediately
### Session Behavior
- **Single login** protects all domains under `*.schweitz.net`
- **Cookie domain**: Shared across all sites
- **Persistent**: Survives browser restarts (until expiration/logout)
- **Secure**: HTTPS-only, HttpOnly flag set
## Protected Domains
The following domains are protected with Authentik forward auth:
1. **192.168.86.149** - Direct IP access
2. **amp.schweitz.net** - AMP Server
3. **cloud.schweitz.net** - Nextcloud
4. **code.schweitz.net** - VS Code Server
5. **git.schweitz.net** - Gitea
6. **home.schweitz.net** - Home Assistant/Dashboard
7. **media.schweitz.net** - Media Server
8. **tatlock.schweitz.net** - Tatlock Services
9. **tower-of-joy** - Tower of Joy Services
### Unprotected Domains
- **auth.schweitz.net** - Authentik itself (cannot protect the auth provider)
## User Management
### Adding Users
1. Go to https://auth.schweitz.net/if/admin/
2. Navigate to **Directory** → **Users**
3. Click **Create** → **Create and enroll user**
4. Enter user details
5. Send enrollment invite (they'll set up Google OAuth)
### User Access Control
Currently, **all authenticated users** can access protected sites. To restrict access:
1. Go to https://auth.schweitz.net/if/admin/#/core/applications
2. Select **NPM Forward Auth** application
3. Go to **Policy / Group / User Bindings**
4. Add specific users or groups
### Group-Based Access (Future)
You can create groups and assign different access levels:
- `admin` - Full access to all sites
- `family` - Access to media, home
- `developers` - Access to code, git
## Logout
Users can log out at: https://auth.schweitz.net/if/user/#/settings
Click **Sign Out** to invalidate the session across all protected sites.
## Technical Implementation
### Authentik Components
1. **Proxy Provider** (`npm-forward-auth-provider`)
- Mode: `forward_single`
- External Host: `https://auth.schweitz.net`
- Token Validity: 480 minutes
2. **Application** (`NPM Forward Auth`)
- Links provider to user interface
- Accessible at: https://auth.schweitz.net
3. **Outpost** (`authentik Embedded Outpost`)
- Handles authentication requests from NPM
- Endpoint: `http://authentik-server:9000/outpost.goauthentik.io`
### NPM Configuration
Each proxy host has advanced nginx configuration:
```nginx
# Forward auth to Authentik
auth_request /outpost.goauthentik.io/auth/nginx;
# Preserve cookies
auth_request_set $auth_cookie $upstream_http_set_cookie;
add_header Set-Cookie $auth_cookie;
# Extract user info
auth_request_set $authentik_username $upstream_http_x_authentik_username;
auth_request_set $authentik_groups $upstream_http_x_authentik_groups;
auth_request_set $authentik_email $upstream_http_x_authentik_email;
# Pass to backend
proxy_set_header X-authentik-username $authentik_username;
proxy_set_header X-authentik-email $authentik_email;
# Redirect on auth failure
error_page 401 = @authentik_proxy_signin;
location @authentik_proxy_signin {
return 302 /outpost.goauthentik.io/start?rd=$scheme://$http_host$request_uri;
}
# Auth endpoint
location /outpost.goauthentik.io {
proxy_pass http://authentik-server:9000/outpost.goauthentik.io;
proxy_set_header X-Original-URL $scheme://$http_host$request_uri;
proxy_pass_request_body off;
}
```
## Backend Application Integration
Protected applications receive user information via headers:
- `X-authentik-username` - Username
- `X-authentik-email` - Email address
- `X-authentik-groups` - Comma-separated groups
- `X-authentik-name` - Full name
- `X-authentik-uid` - Unique user ID
Applications can use these headers for:
- Displaying user info
- Audit logging
- Role-based access control
- Personalization
## Troubleshooting
### User Can't Log In
1. **Check Authentik status**: `docker ps | grep authentik`
2. **Check Authentik logs**: `docker logs authentik-server`
3. **Verify Google OAuth**:
- Go to https://auth.schweitz.net/if/admin/#/core/sources
- Ensure Google source is enabled
4. **Check user exists**:
- Go to https://auth.schweitz.net/if/admin/#/identity/users
- Verify user account is active
### Redirect Loop
If users get stuck in a redirect loop:
1. **Clear browser cookies** for `*.schweitz.net`
2. **Check NPM config**: Ensure `/outpost.goauthentik.io` location exists
3. **Restart NPM**: `docker restart npm`
4. **Check outpost**: Verify provider is assigned to outpost
### 502 Bad Gateway
If auth requests fail:
1. **Check Authentik container**: `docker ps | grep authentik`
2. **Verify network**: Ensure NPM can reach `authentik-server:9000`
3. **Check NPM logs**: `docker logs npm`
### Session Expires Too Quickly
If users are logged out unexpectedly:
1. **Check token validity**: Should be 480 minutes (8 hours)
2. **Verify rolling expiration**: Active use should extend session
3. **Check system time**: Ensure Docker host time is correct
## Automation
### Adding Forward Auth to New Sites
When creating new proxy hosts via core-api:
```python
from src.clients.npm_client import get_npm_client
npm = get_npm_client()
# Create proxy host
proxy = await npm.create_proxy_host(
domain_names=["newsite.schweitz.net"],
forward_host="backend-container",
forward_port=8080,
ssl_enabled=True
)
# Enable forward auth
await npm.enable_authentik_forward_auth(proxy["id"])
```
### Bulk Enable/Disable
To enable on all hosts:
```bash
docker exec core-api /venv/bin/python /app/enable_npm_forward_auth.py
```
## Security Considerations
1. **HTTPS Required**: Forward auth should only be used with HTTPS
2. **Secure Cookies**: HttpOnly and Secure flags prevent XSS/MITM
3. **Token Rotation**: Tokens are rotated on activity for security
4. **Audit Logging**: Authentik logs all authentication events
5. **MFA Support**: Can be enabled in Authentik for additional security
## Monitoring
### Check Authentication Status
```bash
# Check Authentik health
curl http://authentik-server:9000/-/health/live/
# Check active sessions (in Authentik admin)
# https://auth.schweitz.net/if/admin/#/events/log
```
### Monitor Failed Attempts
Go to **System** → **Events** in Authentik admin to see:
- Failed login attempts
- Successful authentications
- Token expirations
- Policy violations
## Future Enhancements
1. **Per-Site Access Control**: Different user groups for different domains
2. **Multi-Factor Authentication**: SMS/TOTP for high-security sites
3. **Rate Limiting**: Prevent brute force attacks
4. **IP Whitelisting**: Allow certain IPs without auth
5. **API Key Support**: Service-to-service authentication

# OIDC Authentication Configuration
## Overview
Core-API has been configured with OIDC authentication support using Authentik as the identity provider. This provides secure authentication for infrastructure management endpoints.
## Current Status
**OIDC is currently DISABLED** (`oidc_enabled=false` in config.py)
This allows:
- Internal services to access the API without authentication
- Direct API access from the Docker network
- Backward compatibility with existing integrations
## Authentik Configuration
### Provider Details
- **Provider Name**: `core-api-provider`
- **Provider ID**: `1`
- **Client ID**: `core-api`
- **Client Secret**: `WfsY0iIVOmO1wvXn1u8jwa08eiQsn2yVf9toBwVyEqps3M98nOZwJMgDOqH5PNZGM6wIxKTwlwYemtaOUg9u5bocd0EqShyoe4yhBQq4SDd0svyArILHZeGHFVEqUi4d`
- **Issuer**: `https://auth.schweitz.net/application/o/core-api/`
### Application Details
- **Application Name**: `Core API`
- **Slug**: `core-api`
- **Launch URL**: `http://localhost:8083/docs`
### Redirect URIs
- `http://localhost:8083/docs/oauth2-redirect`
- `https://core-api.schweitz.net/docs/oauth2-redirect`
- `http://192.168.86.149:8083/docs/oauth2-redirect`
## Enabling OIDC Authentication
When ready to enable OIDC authentication for external access:
### 1. Update core-api Configuration
In `/home/jpmschweitzer/Projects/portainer-core/services/core-api/src/config.py`:
```python
# OIDC Authentication (Authentik)
oidc_enabled: bool = True # Change from False to True
oidc_issuer: str = "https://auth.schweitz.net/application/o/core-api/"
oidc_audience: str = "core-api"
oidc_client_secret: str = "WfsY0iIVOmO1wvXn1u8jwa08eiQsn2yVf9toBwVyEqps3M98nOZwJMgDOqH5PNZGM6wIxKTwlwYemtaOUg9u5bocd0EqShyoe4yhBQq4SDd0svyArILHZeGHFVEqUi4d"
```
### 2. Restart core-api
```bash
docker restart core-api
```
### 3. Test Authentication
1. Visit: http://localhost:8083/docs
2. Click the "Authorize" button
3. Log in with Google via Authentik
4. Access protected endpoints
## Protected Endpoints
When OIDC is enabled, the following endpoints require admin authentication:
### Infrastructure Management (Write Operations)
- `POST /infrastructure/services` - Deploy stack
- `PUT /infrastructure/services/{name}` - Update stack
- `DELETE /infrastructure/services/{name}` - Delete stack
- `POST /infrastructure/proxy` - Create proxy host
- `POST /infrastructure/services/{name}/stop` - Stop service
- `POST /infrastructure/services/{name}/start` - Start service
### Monitoring Management
- `POST /infrastructure/monitors` - Create monitor
- `PUT /infrastructure/monitors/{monitor_id}` - Update monitor
- `DELETE /infrastructure/monitors/{monitor_id}` - Delete monitor
### Read Endpoints (Public)
All GET endpoints remain publicly accessible:
- `/health` - Health check
- `/infrastructure/health` - Infrastructure health
- `/infrastructure/services` - List services
- `/infrastructure/ports` - List ports
- `/infrastructure/domains` - List domains
- `/infrastructure/monitors` - List monitors
## Internal Network Access
**Important**: After enabling OIDC for external users, internal services still need unrestricted access.
### Future Enhancement Options
1. **Network-based Authentication**
- Check if request originates from `docker-dataplane` network
- Allow requests from internal IPs without auth
- Require OIDC only for external requests
2. **Service Accounts**
- Create machine tokens for internal services
- Use Bearer token authentication for service-to-service calls
- Keep OIDC for user authentication
3. **NPM Proxy Layer**
- External domain (https://core-api.schweitz.net) → Requires Authentik SSO
- Internal access (http://core-api:8083) → No authentication
## Admin Groups
Users must be members of one of these Authentik groups to access protected endpoints:
- `admin`
- `authentik Admins`
Configure user group membership in Authentik admin panel:
https://auth.schweitz.net/if/admin/#/identity/users
## Authentik Management
- **Admin Panel**: https://auth.schweitz.net/if/admin/
- **Applications**: https://auth.schweitz.net/if/admin/#/core/applications
- **Providers**: https://auth.schweitz.net/if/admin/#/core/providers
## API Token Management
The Authentik API token used for automation is stored in:
`/home/jpmschweitzer/Projects/portainer-core/services/core-api/src/credentials.py`
```python
AUTHENTIK_CORE_API_TOKEN = "peXM0EzDv2Wiwycbfm3cE5O44IMAOR8ntUwKVP977yFvVopCzDlKY8tymlMM"
```
To create additional tokens: https://auth.schweitz.net/if/admin/#/identity/tokens
## Security Considerations
1. **Client Secret**: Stored in config.py (gitignored), consider moving to environment variable
2. **Token Validation**: Tokens are validated using JWKS from Authentik
3. **Token Expiry**: Access tokens valid for 60 minutes, refresh tokens for 30 days
4. **SSL**: All production endpoints should use HTTPS (via NPM)
5. **Admin Access**: Restrict admin group membership carefully
## Troubleshooting
### Login Issues
- Check Authentik service status: `docker ps | grep authentik`
- Check Authentik logs: `docker logs authentik-server`
- Verify redirect URIs match exactly in Authentik provider config
### Token Validation Errors
- Verify OIDC issuer URL is correct
- Check core-api logs: `docker logs core-api`
- Ensure Authentik is accessible from core-api container
### Permission Denied (403)
- Verify user is member of `admin` group in Authentik
- Check user claims in JWT token at https://jwt.io

## Progress Log
### 2025-11-15 - 21:20 CET
**[Completed]** Shared Infrastructure Architecture
- ✅ Designed shared PostgreSQL + Redis architecture
- ✅ Created `SHARED_INFRASTRUCTURE_ARCHITECTURE.md` documentation
- ✅ Created separate stacks for modularity:
- `postgres-shared.yml` (centralized database)
- `redis-shared.yml` (centralized cache)
- `authentik-shared.yml` (using shared backends)
- ✅ Generated secure credentials (all passwords 32-byte random)
- ✅ Created unified `docker-dataplane` network
- ✅ Created PostgreSQL init script for multi-database setup
- ✅ Created environment files:
- `.env.postgres` (PostgreSQL + app DB passwords)
- `.env.authentik-shared` (Authentik config)
**Architecture Benefits:**
- Resource savings: ~400MB RAM per service using shared infrastructure
- Centralized backups and monitoring
- Easier maintenance and upgrades
- Modular deployment (PostgreSQL and Redis as separate stacks)
**[Next]** Deploy shared infrastructure, then Authentik
---
## Next: Create Authentik Stack
Creating `stacks/authentik.yml` with:
- authentik-server
- authentik-worker
- PostgreSQL database
- Redis cache
Expected resources: ~500MB RAM, 1.5 CPU, 5GB storage
---
## Notes
- **Architecture Decision:** FastAPI native OIDC for core-api (not NPM forward auth)
- **Out of Scope:** Infrastructure tools, data providers, local services
- **Security:** All passwords/secrets via environment variables, not committed to git
