Should we enforce BTP setting validation on TCP/UDP route and update the status?

For example, HTTP-related settings such as FaultInjection, Retries, etc., can't be set when the targeting xRoute is TCP/UDP route or the targeting gateway doesn't contain HTTPRoute.

JuniorJPDJ · 2024-03-25T03:18:07Z

Can I also please ask to add TLSRoute support too?

@JuniorJPDJ
This is already included in the current pull request. Once merged, It will be possible to apply BTP either to specific TLS routes or to the entire gateway.

Sounds good to me. Alternatively, we could update the status of each route to indicate which policies from the BTP are in effect, providing clarity to the user on how their route is affected.

Since this functionality isn't available currently, it might be best to introduce it through a separate change.
WDYT?

arkodg · 2024-03-26T04:28:38Z

hey @zhaohuabing we can't enforce validation here, because if the policy is applied to the Gateway, they could apply to HTTPRoutes as well as TCPRoutes

internal/xds/translator/listener.go

arkodg · 2024-03-26T04:36:35Z

internal/xds/translator/testdata/out/xds-ir/listener-tcp-keepalive.clusters.yaml

  outlierDetection: {}
  perConnectionBufferLimitBytes: 32768
  type: EDS
+  upstreamConnectionOptions:


the test is for listener side keep alive, how did this config come here (cluster) ?

The TCP keep-alive setting is specified in the IR, resulting in a keep-alive configuration for the TCP listener cluster. Typically, such settings are adjusted through a traffic policy, i'm not certain if this make sense in this context.

- name: "fourth-listener" address: "0.0.0.0" tcpKeepalive: probes: 10 port: 10083 destination: name: "tcp-route-dest" settings: - endpoints: - host: "1.2.3.4" port: 50000

can you raise a follow up issue for this ?

-	if tcpkeepalive.Probes != nil {
+	if tcpkeepalive.IdleTime != nil {


thanks for catching this

internal/gatewayapi/backendtrafficpolicy.go

+		if t.MergeGateways && gatewayName != policyTarget {
+			continue
+		}
+


you probably also need some code similar to L500-510

// If any of the features are already set, it means that a more specific // policy(targeting xRoute) has already set it, so we skip it. // TODO: zhaohuabing group the features into a struct and check if all of them are set if r.RateLimit != nil || r.LoadBalancer != nil || r.ProxyProtocol != nil || r.HealthCheck != nil || r.CircuitBreaker != nil || r.FaultInjection != nil || r.TCPKeepalive != nil || r.Retry != nil || r.Timeout != nil { continue }

arkodg · 2024-03-26T04:45:56Z

+			continue
+		}
+
+		udp.LoadBalancer = lb


same as above comment

arkodg · 2024-03-26T04:47:30Z

thanks for adding support for this @alexwo !

Should we enforce validation when the target is a xRoute? It would be confusing if HTTP-related setting is configured for TCP/UDP route.

And it would be nice if we could allow users to know which settings in the BTP can be applied to which type of route. Probably add some comments to BTP settings?
