Config not loaded properly when instantiating InetUtils in HostInfoEnvironmentPostProcessor

[CC007]

When org.springframework.cloud.client.HostInfoEnvironmentPostProcessor (on line 60) is trying to use the config from spring.cloud.inetutils for the instantiation of org.springframework.cloud.commons.util.InetUtils, the config isn't loaded correctly.

InetUtils in org.springframework.cloud.commons.util.UtilAutoConfiguration doesn't seem to have the same issue, because that one seems to get fully initialized before use.

This leads to a significant startup delay, because I'm using a vEthernet (External switch) adapter from hyper-v to route my internet (this was needed to get LAN IP addresses for my hyper-v VMs).
Adding...

spring:
  cloud:
    inetutils:
      preferred-networks:
        - 192.168

...should have fixed this, but due to the config not getting picked up in the post processor, the startup delay is not fully prevented.

spring-cloud-commons version: 4.0.2
sample project: https://github.com/CodeQualIT/CQITFunctions

[CC007]

For clarification, the delay is caused by a timeout in InetUtils on line 167 in the method convertAddress(...)

hostname = result.get(this.properties.getTimeoutSeconds(), TimeUnit.SECONDS);

Thanks for reporting this @CC007. Will try to get to it this week.

[CC007]

Thanks!

You probably already saw, but the provided git repo is the same as the one from issue spring-cloud/spring-cloud-openfeign#860

If you run it without the "native" profile, you won't have the problems from that issue. That'll make it easier to manage those issues separately.

Hello @CC007. There are many different modules in that repo. I do not see any properties in https://github.com/CodeQualIT/CQITFunctions/tree/master/pocs/boxedhello-project/boxedhello-generated/boxedhello-clients/boxedhello-helloworld-client; or is this a different module that should be used to reproduce it? Could you maybe provide a minimal sample containing only the modules necessary to reproduce the issue, as well as reproduction steps.

[CC007]

I created a new minimalized version of the BoxedHello app.
You can find a minimal sample here: https://github.com/CodeQualIT/CQITFunctions/tree/master/pocs/boxedhello-minimal-project

The application module is here: https://github.com/CodeQualIT/CQITFunctions/tree/master/pocs/boxedhello-minimal-project/boxedhello-minimal-app
The feign client is here: https://github.com/CodeQualIT/CQITFunctions/blob/master/pocs/boxedhello-minimal-project/boxedhello-minimal-app/src/main/java/nl/cqit/function/poc/java/boxedhello/services/helloworld/HelloWorldService.java
The config file with the inetutils config can be found here: https://github.com/CodeQualIT/CQITFunctions/blob/master/pocs/boxedhello-minimal-project/boxedhello-minimal-app/src/main/resources/application.yaml

[CC007]

You can start the app here: https://github.com/CodeQualIT/CQITFunctions/blob/master/pocs/boxedhello-minimal-project/boxedhello-minimal-app/src/main/java/nl/cqit/function/poc/java/boxedhello/Main.java

The endpoint can be called on localhost:8090

Example call:

POST http://localhost:8090/boxedHello
Content-Type: application/json

{
  "firstName": "Olga",
  "lastName": "Maciaszek"
}

This app uses a feign client that connects to the HelloWorld app (https://github.com/CodeQualIT/CQITFunctions/tree/master/pocs/helloworld-project), which can be started here: https://github.com/CodeQualIT/CQITFunctions/blob/master/pocs/helloworld-project/helloworld-generated/helloworld-app/src/main/java/nl/cqit/function/poc/java/helloworld/Main.java

That app listens on localhost:8080

Example call:

POST http://localhost:8080/helloWorld
Content-Type: application/json

{
  "firstName": "Olga",
  "lastName": "Maciaszek"
}

Any progress regarding this issue?

[OlgaMaciaszek]

Hi @CC007 , we will take a look at this issue, but it's not high priority, so it will take us some time to get to it.

[CC007]

Is there any place where I can see the progress and prioritization of these issues?

[OlgaMaciaszek]

Here. If it's assigned to a project, project assignment labels and milestones will be added. Any relevant discussion will also happen here.

[CC007]

Due to startup time being very important for cloud applications that scale down to 0 running instances, this is a blocking issue for me. With that in mind, could you please reconsider the priority?

[CC007]

any updates on this issue?

[OlgaMaciaszek]

Thanks for the sample, @CC007. I was able to reproduce the issue. We'll look into it.

[OlgaMaciaszek]

Config resource application.yaml is not listed in the Environment's property sources during the HostiInfoEnvironmentPostProcessor execution, but is there when UtilAutoConfiguration is instantiated.

[CC007]

Confirmed that I now have a startup time of 0.091s
