Values

passthrough → const TlsMode

The SNI string presented by the client will be used as the match criterion in a VirtualService TLS route to determine the destination service from the service registry.

simple → const TlsMode

Secure connections with standard TLS semantics.

mutual → const TlsMode

Secure connections to the downstream using mutual TLS by presenting server certificates for authentication.

autoPassthrough → const TlsMode

Similar to the passthrough mode, except servers with this TLS mode do not require an associated VirtualService to map from the SNI value to service in the registry. The destination details such as the service/subset/port are encoded in the SNI value. The proxy will forward to the upstream (Envoy) cluster (a group of endpoints) specified by the SNI value. This server is typically used to provide connectivity between services in disparate L3 networks that otherwise do not have direct connectivity between their respective endpoints. Use of this mode assumes that both the source and the destination are using Istio mTLS to secure traffic. In order for this mode to be enabled, the gateway deployment must be configured with the ISTIO_META_ROUTER_MODE=sni-dnat environment variable.

istioMutual → const TlsMode

Secure connections from the downstream using mutual TLS by presenting server certificates for authentication. Compared to Mutual mode, this mode uses certificates, representing gateway workload identity, generated automatically by Istio for mTLS authentication. When this mode is used, all other fields in TLSOptions should be empty.
