Fix#1 - SECRET_KEY startup validation (config.py, .env):
- App refuses to start if SECRET_KEY is missing, shorter than 32 chars,
or matches a known insecure default value
- .env: replaced hardcoded test key with placeholder + generation hint
Fix#2 - Docker socket proxy (docker-compose.yml):
- Add tecnativa/docker-socket-proxy sidecar
- Only expose required Docker API endpoints (CONTAINERS, IMAGES,
NETWORKS, POST, EXEC); dangerous endpoints explicitly blocked
- Remove direct /var/run/docker.sock mount from main container
- Route Docker API via DOCKER_HOST=tcp://docker-socket-proxy:2375
Fix#3 - Azure AD group whitelist (auth.py, models.py, validators.py):
- New azure_allowed_group_id field in SystemConfig
- After token exchange, verify group membership via Graph API /me/memberOf
- Deny login with HTTP 403 if user is not in the required group
- New Azure AD users now get role 'viewer' instead of 'admin'
Fix#4 - Rate limiting on login (main.py, auth.py, requirements.txt):
- Add slowapi==0.1.9 dependency
- Initialize SlowAPI limiter in main.py with 429 exception handler
- Apply 10 requests/minute limit per IP on /login and /mfa/verify
Socket detection inside Docker returns the container IP (172.18.0.x),
not the host IP. Now:
- install.sh detects host IP via hostname -I and stores in .env
- docker-compose.yml passes HOST_IP to the container
- npm_service.py reads HOST_IP from environment
- Increased SSL cert timeout to 120s (LE validation is slow)
- Added better logging for SSL cert creation/assignment
- README updated with HOST_IP in .env example
