aeraki's Issues

[question] support more traffic management

Can we use istio+aeraki to do more traffic management our dubbo services, such as circuit break, timeout, retry etc

We need multicluster support

Is your feature request related to a problem? Please describe.
We are now using multi-cluster, but found that the custom protocol configuration MetaRouter on another cluster does not take effect

Describe the solution you'd like
support multicluster

Describe alternatives you've considered
Multi-cluster is a very common scenario

web 站点consumer 无**询

同一个provider，web 站点的consumer无**询，如果是jar包调用可以。刚刚入门，还请大神指点迷经。

Create the generated EnvoyFilters as CRD resources in the K8s APIServer

Is your feature request related to a problem? Please describe.
We can't see the created Envoyfilters by using kubectl command-line tool.
It's because Aeraki is a standalone MCP config server, which isn't visible in the K8s APIServer. This makes it hard to figure out which EnvoyFilters are generated and causing problems for debugging.

Describe the solution you'd like
As an alternative approach, we can create the generated EnvoyFilters as CRD resources in the K8s APIServer.

Describe alternatives you've considered
We can also get all the config in Istiod with the following command, including the EnvoyFilters generated by Aeraki.
kubectl exec istiod-7b7d8974f6-htbjf -n istio-system -- curl http://127.0.0.1:15014/debug/configz

【lazyxds】svc注解优先级是否应当高于namespace注解

aeraki/lazyxds/pkg/model/service.go

Lines 181 to 186 in f9c827e

 if svc.NSLazy == NSLazyStatusDisabled { 

 spec.LazyEnabled = false 

 } else if svc.NSLazy == NSLazyStatusEnabled { 

 spec.LazyEnabled = true 

 } 

 spec.LazyEnabled = spec.LazyEnabled || cs.LazyEnabled

不知道是不是理解的不对，我的理解是svc中的注解应该覆盖namespace中的注解，

此处如果使用'||' 的关系，则只要两者有一个为true，那么这个svc就会生效lazyxds

Query: How to handle database secure connection with Aeraki

Aeraki project is amazing, one impressing scenario is that "Manage authentication for other system, like databases". I would like to know how Aeraki handle database secure connection, like mySQL SSL connection, especially when the database certificate is issued by third party. Is there any example or guide?

Support Custom Protocol

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

我们目前想要使用Aeraki来给Grpc实现类似Dubbo的路由功能，但看了一下Aeraki协议定义的代码，在解析的时候，只能解析成枚举，不能解析成任意的字符串

https://github.com/aeraki-framework/aeraki/blob/a2686631e9b0659b9d78322735d6517d9ebd2751/pkg/model/protocol/instance.go#L24-L67

这导致对Aeraki协议扩展的时候会变得很麻烦，只能把某种实现给覆盖掉。如果将来有一天又要用到这种协议，就会很麻烦。

是否可以考虑放开AerakiArgs#Protocols的配置，这样只要在main中自己注册特定的插件就可以比较方便的扩展Aeraki的协议。几乎不会动到aeraki的源码就能进行扩展。

解析的时候如果不存在不要返回 Unsupported，而是直接返回这个字符串

https://github.com/aeraki-framework/aeraki/blob/a2686631e9b0659b9d78322735d6517d9ebd2751/cmd/aeraki/main.go#L76-L83

还有看了一下meta-protocol-proxy方案，好像也能做，但是对于Envoy已经支持的协议，好像要做用C++重写，感觉有点复杂了

lazyxds: change lazy annotation need restart lazy controller

Describe the bug

第一次更新annotations（无论是对svc还是ns），lazy是ok的，router信息是对的；
后续对annotate的任何变更，都只有重启lazyxds controller才能生效。

Kafka Helm repo link dead, causing demo setup to fail

Describe the bug
When attempting to run the demo app, the bash script fails in demo/kafka/insall.sh when running the line
helm repo add zhaohuabing http://zhaohuabing.com/helm-repo/

To Reproduce
Steps to reproduce the behavior:

make demo

Expected behavior
The full demo application suite is successfully installed.

[lazyxds] lazyxds create wrong sidecar CRD for service which type is externalName

Describe the bug
For Service with externalName type, currently lazy xds will handle it the same as cluster ip. But externalName service does not have selector field, so it will create Sidecar CRD with empty workload selector. According to istio docs, In the absence of a workloadSelector, it will apply to all workload instances in the same namespace. It is very dangerous.

To Reproduce
Steps to reproduce the behavior:

Create service with externalName type, such as:

apiVersion: v1
kind: Service
metadata:
  name: example
  namespace: default
spec:
  externalName: www.baidu.com
  ports:
  - name: https
    port: 443
    protocol: TCP
    targetPort: 443
  sessionAffinity: None
  type: ExternalName

Kubectl get sidecar lazyxds-example -o yaml

apiVersion: networking.istio.io/v1beta1
kind: Sidecar
metadata:
  name: lazyxds-example
  namespace: default
spec:
  egress:
  - hosts:
    - istio-system/*
    - ...
  workloadSelector: {}

Expected behavior

I do not have perfect solution, maybe it's not necessary to generate Sidecar CRD for externalName service?

Also, currently there is no way to disable lazy XDS for the specified service, if I annotate azy-xds=true for one namespace.

Need istio-ingress-gateway metaprotocol support

Is your feature request related to a problem? Please describe.
we can't match metarouter with istio-ingress-gateway now

Describe the solution you'd like
istio-gress-gateway support metaprotocol maybe is a good idea

Describe alternatives you've considered

meta-protocol-proxy 是否能够得到pilot-discovery的支持？

对meta-protocol-proxy支持第三方私有协议的支持功能很感兴趣，简单阅读了相关代码后有个疑问: "如果我添加了私有协议，aeraki生成了相应的envoyfilter，istio支持应用(apply)该envoyfilter吗？"

似乎aeraki源码上写死了当前只支持dubbo/thrift协议？

因为近期自己也在做私有协议上的扩展，istio在应用envoyfilter前会通过webhook进行校验，对不识别的proxy将直接返回报错: Envoy filter: could not resolve Any message type: xxx_proxy,因此必须要编译envoy之后将相应的pb.go同步到go-control-plane，isltio引用后才能识别, 这样就不得不编译pilot-discovery了。

When the same service has multiple clusters and multiple virtual IP scenarios, the service only takes effect in one cluster configuration

Describe the bug
a service deploy in multiple clusters, only one cluster configuration takes effect

To Reproduce
Steps to reproduce the behavior:

compare with Multi cluster with istio
deploy one service in Multi cluster
Push traffic split policy

metaprotocol router match error

Describe the bug
When I use metaprotocol, when the route matching condition is multiple, it is reflected as an OR relationship. When dumping the configuration, it is found that the delivery rules and the configuration rules are inconsistent.

To Reproduce
Steps to reproduce the behavior:
configure rule is:

  routes:
    - name: traffic-spilt
      match:
        attributes:
          method:
            exact: sayHello
          interface:
            exact: org.apache.dubbo.samples.basic.api.DemoService11
      route:
        - destination:
            host: demoservice.mesh.yonghui.cn
            subset: v2

dump config rule is:

      "routes": [
       {
        "name": "traffic-spilt",
        "match": {
         "metadata": [
          {
           "name": "method",
           "exact_match": "sayHello"
          },
          {
           "name": "method",
           "exact_match": "sayHello"
          }
         ]
        },

Expected behavior
The configuration rules are consistent with the delivery rules.

why don't you use mcp over xds?

as we all know, istio 1.9 removed some mcp support

Inboud listener port conflicts

We need to use workloadselector to distinguish different services at inbound listeners on the same port.

请问下使用meta-protocol方式管理dubbo流量，consumer 必须是直连的方式吗

关于懒加载对于ServiceEntry的处理

目前代码里面看到对于ServiceEntry是全量下发给所有的Sidecar，这个是出于什么考虑呢？我们公司目前的做法是以ServiceEntry为主，Service几乎没有，这种场景下面，我们相当于还是全量下发配置了，后续是否会考虑增加针对ServiceEntry的懒加载

crd update order may cause service access exception

as we can see, the reconcileLazyService will update envoy filter first, so maybe the request is send, but envoy filter lack some service, but sidecar is not fully effective.

lazyXDS: why need create envoyfilter for every service and file size is too large

Is your feature request related to a problem? Please describe.

Every service will be created a EnvoyFilter resource, the EnvoyFilter contains all the services needing redirect to global sidecar and file is too large if have many services.

Rules are configured for each service, is there a performance problem(in match stage OR xds merge stage)?

I know the EnvoyFilter will add header lazyxds-service-address before forwarding the service and egress will route according to this header. Why not let egress cache all the configurations to avoid this route?

I'm not an expert in istio, maybe I don't think carefully in many places, thank you for answering my questions.

Use Dubbo's metadata to match routes

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
Per we used dubbo for rpc calls, and expect to build gray deploy, and we may use different indicators for gray routing, such as version/userId ... now we can only add a spring starter to resolve this problem per Istio does not support TCP calls friendly

Describe the solution you'd like
A clear and concise description of what you want to happen.
If there any method to route by dubbo metadata（such as provider's version is 1.0.0, the consumer is also 1.0.0, it can select the 1.0.0 provider）

Aeraki Control Plane for MetaProtocol Proxy

Create EnvoyFilter for MetaProtocol services to replace the default TCP proxy with a metaprotocol proxy
Implement RDS server for MetaProtocolPxoy
Create a new CRD to define application Protocol built on top of metaprotocol
Create a new CRD for metaprotocol route configuration

provider存在多个version/group时，consumer会访问到version/group不匹配的provider实例而报错

dubbo服务端通过@service注解配置2个版本1.0.0 和2.0.0，打包为不同版本的镜像运行，同时注册到zk

@Service(version = "1.0.0", group = "dev")
public class DemoServiceImpl implements DemoService {}

@Service(version = "2.0.0", group = "dev")
public class DemoServiceImpl implements DemoService {}

运行dubbo2istio，将provider同步到k8s集群生成相应的serviceentry。

通过@reference注解配置dubbo consumer的version

@Reference(version = "1.0.0", group = "dev" ,url = "dubbo://com.test.dubbo.sentinel.example.demoservice:20880" )
private DemoService demoService;

启动consumer后一半流量被分配到2.0.0版本的provider实例，但dubbo sdk对version/group有校验，于是报错：

org.apache.dubbo.remoting.RemotingException: Not found exported service: dev/com.test.dubbo.sentinel.example.DemoService:1.0.0:20880 in [dev/com.test.dubbo.sentinel.example.DemoService:2.0.0:20880], may be version or group mismatch , channel: consumer: /127.0.0.1:60798 --> provider: /127.0.0.1:20880, message:RpcInvocation [methodName=sayHello, parameterTypes=[class java.lang.String], arguments=null, attachments={path=com.test.dubbo.sentinel.example.DemoService, remote.application=sentinel-demo-consumer, dubboApplication=sentinel-demo-consumer, dubbo=2.0.2, sdk=0.7.0, interface=com.test.dubbo.sentinel.example.DemoService, version=1.0.0, group=test}]
	at org.apache.dubbo.rpc.protocol.dubbo.DubboProtocol.getInvoker(DubboProtocol.java:266) ~[dubbo-2.7.4.1.jar!/:2.7.4.1]

	at org.apache.dubbo.rpc.protocol.dubbo.DecodeableRpcInvocation.decode(DecodeableRpcInvocation.java:73) [dubbo-2.7.4.1.jar!/:2.7.4.1]

此行为和dubbo原生的行为不一致，原生dubbo sdk会在consumer端对provider进行过滤，确保流量不会发送给verison/group不匹配的provider。

启动了两个版本provider，但是每次consumer dubbo调用provider时，都会负载到provider的一个版本

我启动了两个版本，但是每次consumer dubbo调用provider时，都会负载到provider的一个版本：
调用链路结果：

v1 版本的aeraki 路由规则配置：

v2 版本的aeraki路由规则配置：

lazyXDS: App's virtualservice route rule hasn't effected while first accessing to it

Describe the bug
App's virtualservice route rule hasn't effected while first accessing to it

To Reproduce
In my bookinfo example, i create a Virtualservice for app of Reviews like below:

Virtualservices:

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: reviews
  namespace: default
spec:
  hosts:
  - reviews
  http:
  - route:
    - destination:
        host: reviews
        subset: v1
      weight: 50
    - destination:
        host: reviews
        subset: v3
      weight: 50

So in an ideal situation, the traffic to Reviews should never route to the v2 version. But it does unexpected traffic to v2 version of Reviews during first accessing to.

Additional context
May useful references:
https://istio.io/latest/docs/ops/common-problems/network-issues/#route-rules-have-no-effect-on-ingress-gateway-requests

lazyxds希望能适配discoverySelector

现在服务使用lazyxds后，生成的Sidecar和Envoyfilter会包含网格内所有的service，没有过滤被discoverySelector排除的service，在集群中有大量非网格服务时会比较浪费，希望可以支持。

LazyXDS: support multiple clusters

Currently, LazyXDS only watches the services in the cluster of the controller.

We need support add/delete clusters dynamically，normally watching the cluster related secrets in mater cluster.

add outlier detection ability

Describe the solution you'd like
outlier detection is a key point of service protection, we hope fuse can protect the upstream service when our system in trouble. It can minimize the impact of faults.

缺乏一致性哈希支持

目前的路由方式较少。业务需要在四层协议支持一致性哈希，希望MetaProtocol 能够支持。

Support TLS connection to Istiod

Support service with multiple port

Is your feature request related to a problem? Please describe.
Aeraki generates EnvoyFilete for service with a particular port name, and now it's not working for service with multiple ports.
e.g. service has multiple ports, the second one was reserved for compatibility.

spec:
  clusterIP: 10.134.7.56
  ports:
  - name: tcp-metaprotocol-xxx
    port: 9000
    protocol: TCP
    targetPort: 11206
  - name: tcp
    port: 11206
    protocol: TCP
    targetPort: 11206

Describe the solution you'd like
Except to generate metaprotocol filter for 10.134.7.56_9000.

local ratelimit add metric feature

Describe the solution you'd like
some time,we always hope using this metric as hpa target, because of this metric always earlier than other monitor item

Expose endpoint IP from meta-protocol

Is your feature request related to a problem? Please describe.
We are using meta-protocol to support a private protocol, the problem is, the peer's IP is a part of this protocol. With the service discovery of Kubernetes, the peers cannot get the endpoint IP but the service IP. Theoretically, this is suitable to handle by meta-protocol, since istio-proxy maintain the information of endpoint IP, not just service IP.

After aeraki has been running for some time, envoyfilter cannot be created automatically
