fallback:
description: |-
Fallback indicates whether the backend is designated as a fallback.
It is highly recommended to configure active or passive health checks to ensure that failover can be detected
when the active backends become unhealthy and to automatically readjust once the primary backends are healthy again.
The overprovisioning factor is set to 1.4, meaning the fallback backends will only start receiving traffic when
the health of the active backends falls below 72%.
type: boolean
tls:
description: |-
TLS defines the TLS settings for the backend.
If TLS is specified here and a BackendTLSPolicy is also configured for the backend, the final TLS settings will
be a merge of both configurations. In case of overlapping fields, the values defined in the BackendTLSPolicy will
take precedence.
properties:
alpnProtocols:
description: |-
ALPNProtocols supplies the list of ALPN protocols that should be
exposed by the listener or used by the proxy to connect to the backend.
Defaults:
1. HTTPS Routes: h2 and http/1.1 are enabled in listener context.
2. Other Routes: ALPN is disabled.
3. Backends: proxy uses the appropriate ALPN options for the backend protocol.
When an empty list is provided, the ALPN TLS extension is disabled.
Defaults to [h2, http/1.1] if not specified.
Typical Supported values are:
- http/1.0
- http/1.1
- h2

caCertificateRefs:
description: |-
CACertificateRefs contains one or more references to Kubernetes objects that
contain TLS certificates of the Certificate Authorities that can be used
as a trust anchor to validate the certificates presented by the backend.
A single reference to a Kubernetes ConfigMap or a Kubernetes Secret,
with the CA certificate in a key named `ca.crt` is currently supported.
If CACertificateRefs is empty or unspecified, then WellKnownCACertificates must be
specified. Only one of CACertificateRefs or WellKnownCACertificates may be specified,
not both.
items:
description: |-
LocalObjectReference identifies an API object within the namespace of the
referrer.
The API object must be valid in the cluster; the Group and Kind must
be registered in the cluster for this reference to be valid.
References to objects with invalid Group and Kind are not valid, and must
be rejected by the implementation, with appropriate Conditions set
on the containing object.

clientCertificateRef:

Note that when a namespace different than the local namespace is specified,
a ReferenceGrant object is required in the referent namespace to allow that
namespace's owner to accept the reference. See the ReferenceGrant

Envoy Gateway will use the HTTP host header value for SNI, when all resources referenced in BackendRefs are:
1. Backend resources that do not set SNI, or
2. Service/ServiceImport resources that do not have a BackendTLSPolicy attached to them
When a BackendTLSPolicy attaches to a Backend resource, the BackendTLSPolicy's Hostname value takes precedence
over this value.
