Compute Engine v1 API - Class BackendServiceTlsSettings (3.31.0)

Reference to the BackendAuthenticationConfig resource from the networksecurity.googleapis.com namespace. Can be used in authenticating TLS connections to the backend, as specified by the authenticationMode field. Can only be specified if authenticationMode is not NONE.

Gets whether the "authentication_config" field is set

Gets whether the "identity" field is set

Gets whether the "sni" field is set

Assigns the Managed Identity for the BackendService Workload.

Use this property to configure the load balancer back-end to use certificates and roots of trust provisioned by the Managed Workload Identity system.

The identity property is the fully-specified SPIFFE ID to use in the SVID presented by the Load Balancer Workload.

The SPIFFE ID must be a resource starting with the trustDomain property value, followed by the path to the Managed Workload Identity.

Supported SPIFFE ID format:

• //<trust_domain>/ns/<namespace>/sa/<subject>

The Trust Domain within the Managed Identity must refer to a valid Workload Identity Pool. The TrustConfig and CertificateIssuanceConfig will be inherited from the Workload Identity Pool.

Restrictions:

• If you set the identity property, you cannot manually set the following fields:
  • tlsSettings.sni
    • tlsSettings.subjectAltNames
    • tlsSettings.authenticationConfig

When defining a identity for a RegionBackendServices, the corresponding Workload Identity Pool must have a ca_pool configured in the same region.

The system will set up a read-onlytlsSettings.authenticationConfig for the Managed Identity.

Server Name Indication - see RFC3546 section 3.1. If set, the load balancer sends this string as the SNI hostname in the TLS connection to the backend, and requires that this string match a Subject Alternative Name (SAN) in the backend's server certificate. With a Regional Internet NEG backend, if the SNI is specified here, the load balancer uses it regardless of whether the Regional Internet NEG is specified with FQDN or IP address and port. When both sni and subjectAltNames[] are specified, the load balancer matches the backend certificate's SAN only to subjectAltNames[].

A list of Subject Alternative Names (SANs) that the Load Balancer verifies during a TLS handshake with the backend. When the server presents its X.509 certificate to the Load Balancer, the Load Balancer inspects the certificate's SAN field, and requires that at least one SAN match one of the subjectAltNames in the list. This field is limited to 5 entries. When both sni and subjectAltNames[] are specified, the load balancer matches the backend certificate's SAN only to subjectAltNames[].
