|
* Overview
|
|
|
|
Branch: ~production/security-and-config~
|
|
|
|
This branch addresses critical security issues identified during the production deployment on b612.asteroid.radio and implements a comprehensive configuration system.
|
|
|
|
* Changes Made
|
|
|
|
** Configuration System (~config.lisp~) - NEW FILE
|
|
|
|
Centralized configuration management system with:
|
|
|
|
- Class-based configuration: ~asteroid-config~ class with all configuration parameters
|
|
- Environment variable loading: All config loaded from environment variables
|
|
- Sensible defaults: Development-friendly defaults for local testing
|
|
- Validation: Warns about missing critical configuration (passwords, TLS)
|
|
- Security: Passwords never hardcoded, must be set via environment
|
|
|
|
*** Key Configuration Parameters
|
|
|
|
- Server settings (port, paths)
|
|
- Icecast credentials (user, password)
|
|
- Database backend selection (i-lambdalite or PostgreSQL)
|
|
- PostgreSQL connection details
|
|
- TLS/HTTPS configuration
|
|
- Stream management settings
|
|
|
|
** Configuration Template (~config.template.env~) - NEW FILE
|
|
|
|
Documented template for environment configuration with:
|
|
|
|
- Complete list of all environment variables
|
|
- Security notes and production checklist
|
|
- Examples for development and production
|
|
- Docker networking guidance
|
|
- Backup recommendations
|
|
|
|
** Removed Hardcoded Credentials - SECURITY FIX
|
|
|
|
Eliminated hardcoded Icecast admin password from codebase.
|
|
|
|
*** Files Modified
|
|
|
|
- ~asteroid.lisp~ - Line 814: Now uses ~(config-icecast-admin-password *config*)~
|
|
- ~frontend-partials.lisp~ - Lines 7-8: Now uses config system
|
|
|
|
*** Before
|
|
#+BEGIN_SRC lisp
|
|
:basic-authorization '("admin" "asteroid_admin_2024")
|
|
#+END_SRC
|
|
|
|
*** After
|
|
#+BEGIN_SRC lisp
|
|
:basic-authorization (list (config-icecast-admin-user *config*)
|
|
(config-icecast-admin-password *config*))
|
|
#+END_SRC
|
|
|
|
** Configuration Initialization
|
|
|
|
*** Files Modified
|
|
|
|
- ~asteroid.asd~ - Added ~config.lisp~ to system components (loaded early)
|
|
- ~asteroid.lisp~ - Replaced ~defparameter~ with config system initialization
|
|
- ~*server-port*~ → ~(config-server-port *config*)~
|
|
- ~*music-library-path*~ → ~(config-music-library-path *config*)~
|
|
- ~*supported-formats*~ → ~(config-supported-formats *config*)~
|
|
- ~*stream-base-url*~ → ~(config-stream-base-url *config*)~
|
|
|
|
* TODO Items Addressed
|
|
|
|
** DONE Problem 4: Templates no longer advertise default admin password
|
|
** DONE Server runtime configuration: All configuration parameterized and loaded from environment
|
|
** TODO Problem 3: Database backend selection implemented (PostgreSQL support ready, migration needed)
|
|
|
|
* Production Deployment Issues (From b612.asteroid.radio Test)
|
|
|
|
** Critical Security (Must fix before public launch)
|
|
|
|
- [ ] *Problem 1*: Fix Liquidsoap telnet binding (currently exposed on external interface)
|
|
- Issue: ~telnet asteroid.radio 1234~ works from anywhere
|
|
- Fix: Bind to localhost only in Docker config
|
|
|
|
- [ ] *Problem 2*: Fix Icecast external binding
|
|
- Issue: Icecast binding to 0.0.0.0
|
|
- Fix: Bind to localhost only, use HAproxy to proxy
|
|
|
|
- [ ] *Problem 5*: Set up TLS/Let's Encrypt with HAproxy
|
|
|
|
** Infrastructure
|
|
|
|
- [ ] *Problem 3*: Complete PostgreSQL migration
|
|
- [ ] Create ~.env~ file from template for production
|
|
- [ ] Test configuration loading on production server
|
|
|
|
** Features
|
|
|
|
- [ ] *Problem 6*: Admin interface improvements (deactivate users, permissions)
|
|
- [ ] *Problem 7*: User profile pages
|
|
- [ ] *Problem 8*: Stream management for Admins/DJs
|
|
- [ ] *Problem 9*: Fix "Scan Library" feature
|
|
|
|
** UI Bugs (From Production Test)
|
|
|
|
- [ ] Logout kills the player
|
|
- [ ] Admin → Home navigation loses player widget in non-frameset mode
|
|
|
|
* Deployment Instructions
|
|
|
|
** For Development
|
|
|
|
1. Copy configuration template:
|
|
#+BEGIN_SRC bash
|
|
cp config.template.env .env
|
|
#+END_SRC
|
|
|
|
2. Edit ~.env~ with your settings (at minimum, set passwords)
|
|
|
|
3. Source the environment:
|
|
#+BEGIN_SRC bash
|
|
source .env
|
|
#+END_SRC
|
|
|
|
4. Build and run:
|
|
#+BEGIN_SRC bash
|
|
make clean && make
|
|
./asteroid
|
|
#+END_SRC
|
|
|
|
** For Production (b612.asteroid.radio)
|
|
|
|
1. *CRITICAL*: Set all passwords via environment variables:
|
|
#+BEGIN_SRC bash
|
|
export ICECAST_ADMIN_PASSWORD="your-secure-password"
|
|
export POSTGRES_PASSWORD="your-secure-password"
|
|
#+END_SRC
|
|
|
|
2. Configure production settings:
|
|
#+BEGIN_SRC bash
|
|
export ASTEROID_STREAM_URL="http://asteroid.radio:8000"
|
|
export ASTEROID_DB_BACKEND="postgresql"
|
|
export ASTEROID_TLS_ENABLED="true"
|
|
export ASTEROID_TLS_CERT="/path/to/cert.pem"
|
|
export ASTEROID_TLS_KEY="/path/to/key.pem"
|
|
#+END_SRC
|
|
|
|
3. Fix Docker networking (see Docker section below)
|
|
|
|
4. Build and deploy
|
|
|
|
* Docker Configuration Changes Needed
|
|
|
|
** Liquidsoap (Problem 1)
|
|
|
|
Edit ~docker/docker-compose.yml~ or Liquidsoap config:
|
|
|
|
#+BEGIN_SRC yaml
|
|
ports:
|
|
- "127.0.0.1:1234:1234" # Bind telnet to localhost only
|
|
#+END_SRC
|
|
|
|
** Icecast (Problem 2)
|
|
|
|
Edit ~docker/docker-compose.yml~:
|
|
|
|
#+BEGIN_SRC yaml
|
|
ports:
|
|
- "127.0.0.1:8000:8000" # Bind to localhost only
|
|
#+END_SRC
|
|
|
|
Then use HAproxy to proxy external requests to localhost:8000
|
|
|
|
** Note from Production Test
|
|
|
|
Fade confirmed that setting ~ASTEROID_STREAM_URL~ as environment variable works perfectly:
|
|
- Set to ~http://asteroid.radio:8000~
|
|
- System immediately picked it up
|
|
- Stream worked correctly
|
|
|

* Testing
|
|
|
|
After applying these changes:
|
|
|
|
** Test configuration loading
|
|
#+BEGIN_SRC lisp
|
|
(asteroid::config-summary)
|
|
#+END_SRC
|
|
|
|
** Test Icecast status (should fail if password not set)
|
|
#+BEGIN_SRC bash

|
curl http://localhost:8080/api/asteroid/icecast-status
|
|
#+END_SRC
|
|
|
|
** Set password and test again
|
|
#+BEGIN_SRC bash
|
|
export ICECAST_ADMIN_PASSWORD="your-password"
|
|
# Restart asteroid
|
|
curl http://localhost:8080/api/asteroid/icecast-status
|
|
#+END_SRC
|
|

#+BEGIN_QUOTE
|
|
"I stood up asteroid on b612. It even worked(ish). I didn't leave it running
|
|
because there are gaping security holes in it that need to be ironed out."
|
|
|
|
"The templates with the default passwords for sure need changing. We shouldn't
|
|
announce the login and password information for the default admin user when we
|
|
deploy to prod."
|
|
#+END_QUOTE
|
|
|
|
* Next Steps
|
|
|
|
1. Test build with new configuration system
|
|
2. Fix Docker port bindings (localhost only)
|
|
3. Check templates for password displays
|
|
4. Complete PostgreSQL migration
|
|
5. Set up TLS with Let's Encrypt
|
|
6. Fix UI navigation bugs
|
|
7. Deploy to production
