Phoenix now supports Transport Layer Security (TLS) for both HTTP and gRPC connections, enabling encrypted communication and optional mutual TLS (mTLS) authentication. This enhancement provides a more secure foundation for production deployments.
Secure HTTP & gRPC Connections: Phoenix can now serve over HTTPS and secure gRPC.
Flexible TLS Configuration: TLS settings are managed via environment variables.
Optional Client Verification: Support for mTLS with configurable client certificate validation.
Improved Testing: TLS-aware infrastructure added to integration tests.
Better Visibility: Server startup logs now display TLS status.
Set the following environment variables to enable and customize TLS:
PHOENIX_TLS_ENABLED
boolean
Enable or disable TLS (true
/false
)
PHOENIX_TLS_CERT_FILE
string
Path to TLS certificate file
PHOENIX_TLS_KEY_FILE
string
Path to private key file
PHOENIX_TLS_KEY_FILE_PASSWORD
string
Password for encrypted private key file
PHOENIX_TLS_CA_FILE
string
Path to CA certificate (for client verification)
PHOENIX_TLS_VERIFY_CLIENT
boolean
Enable client cert verification
