feat(ingress gateway: support configuring limits in ingress-gateway c… by huikang · Pull Request #14749 · hashicorp/consul

huikang · 2022-09-26T14:20:02Z

Description

As a user of ingress gateway, I want to increase the max_connections of the service in the ingress-gateway config entry (link to the detailed description). However, in current implementation, max_coonections can’t be changed and is set to the default value of 1024 by envoy.

This PR adds a new field named Defaults to the ingress-gateway config entry and max_xyz to individual listening services. The new fields allow user to configure the max_xyz of the upstream cluster of a specified service behind the ingress gateway.

updated unit test and integration test
updated external-facing doc

Fixes #13374

Testing & Reproduction steps

A full example is verified in the integration test (test/integration/connect/envoy/case-ingress-gateway-multiple-services/config_entries.hcl).

Kind = "ingress-gateway"
Name = "my-ingress-gateway"

Defaults {
    MaxConnections = 2048          // <----- increase the max_connections of all upstream service instances
}
Listeners = [
 {
   Port = 8082
   Protocol = "http"
   Services = [
     {
        Name = "counting"
        Hosts = ["*"]
        MaxConnections = 5120          // <----- increase the max_connections, overwrite the value in Defaults
     },
     {
       Name = "counting-v2"
       Hosts = ["v2"]
     }
   ]
 }
]

I had some editorial comments we could discuss but overall looks great!

Should we mention the default values?

I would provide a link to these configuration items.

+	MaxConnections        int32
+	MaxPendingRequests    int32
+	MaxConcurrentRequests int32


uint32 would be more accurate per envoy, correct?
