Summary
Self-hosted customers often use organization-signed certificates which are not supported when using
rustls-tls(unlikenative-tlswhich picks up system SSL environment variables). This change adds support for custom CA certificates and optionally disabling TLS verification entirely.We read these environment variables directly from the OS rather than through connector configuration, as TLS settings are primarily an infrastructure concern.
Environment Variables
GRAPHQL_CA_CERT_FILEGRAPHQL_CA_CERT_DIR.pem,.crt,.cer)GRAPHQL_INSECURE_SKIP_TLS_VERIFYtrueor1to disable TLS verification (dangerous, for dev/testing only)Notes:
GRAPHQL_CA_CERT_FILEandGRAPHQL_CA_CERT_DIRcan be used together (certificates are combined)GRAPHQL_INSECURE_SKIP_TLS_VERIFYtakes precedence and skips all CA cert logic when enabledChanges
