Enum Resolution

Resolution determines how the proxy will resolve the IP addresses of the network endpoints associated with the service, so that it can route to one of them. The resolution mode specified here has no impact on how the application resolves the IP address associated with the service. The application may still have to use DNS to resolve the service to an IP so that the outbound traffic can be captured by the Proxy. Alternatively, for HTTP services, the application could directly communicate with the proxy (e.g., by setting HTTP_PROXY) to talk to these services.

Fields

Name	Description
Dns	Attempt to resolve the IP address by querying the ambient DNS, asynchronously. If no endpoints are specified, the proxy will resolve the DNS address specified in the hosts field, if wildcards are not used. If endpoints are specified, the DNS addresses specified in the endpoints will be resolved to determine the destination IP address. DNS resolution cannot be used with Unix domain socket endpoints.
DnsRoundRobin	Attempt to resolve the IP address by querying the ambient DNS, asynchronously. Unlike DNS, DNSROUNDROBIN only uses the first IP address returned when a new connection needs to be initiated without relying on complete results of DNS resolution and connections made to hosts will be retained even if DNS records change frequently eliminating draining connection pools and connection cycling. This is best suited for large web scale services that must be accessed via DNS. The proxy will resolve the DNS address specified in the hosts field, if wildcards are not used. DNS resolution cannot be used with Unix domain socket endpoints.
None	Assume that incoming connections have already been resolved (to a specific destination IP address). Such connections are typically routed via the proxy using mechanisms such as IP table REDIRECT/ eBPF. After performing any routing related transformations, the proxy will forward the connection to the IP address to which the connection was bound.
Static	Use the static IP addresses specified in endpoints (see below) as the backing instances associated with the service.
