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.

Highlights:

  • 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.

Configuration Options

Set the following environment variables to enable and customize TLS:

Variable
Type
Description

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

Note: Encrypted private keys require the cryptography Python package for decryption.
