Integration stuck at Building Kit if properties are defined, but the runtime is not

[lsergio]

What happened?

Consider the following Integration:

apiVersion: camel.apache.org/v1
kind: Integration
metadata:
  name: bugproperties
spec:  
  sources:
  - name: main.yaml
    content: |-
      - from:
          uri: rest:get:/demo
          steps:
          - setBody:
              constant: "It worked"
  traits:
    health:
      enabled: true
    camel:
      properties:
      - hello=world

When I apply it to my cluster, the Integrations remains stuck at Building Kit:

k get it
NAME            PHASE          READY   RUNTIME PROVIDER   RUNTIME VERSION   KIT   REPLICAS
bugproperties   Building Kit           quarkus            3.2.3                   

If I include the runtimeVersion at the camel trait:

    camel:
      runtimeVersion: 3.2.3
      properties:
      - hello=world

or remove the trait completely, the integration build finishes successfully.

I checked the operator log and there is no error message related to the trait. Logs look good as usual.

Steps to reproduce

No response

Relevant log output

No response

Camel K version

2.4.0

[squakez]

Can you verify the status of IntegrationKit and Build resources as well? I think that you have some building against the default Camel version (3.8.1 in Camel K 2.4.0) which are failing for some reason. Likely, setting the runtime version would reuse the existing Kit.

[lsergio]

@squakez sure. Here are some more details.

My Integrationplatform is setup so the default runtime is 3.2.3:

  traits:
    builder:
      incrementalImageBuild: true
      nodeSelector:
        kubernetes.io/arch: amd64
    camel:
      runtimeVersion: 3.2.3
    deployment:
      progressDeadlineSeconds: 600
    pull-secret:
      secretName: gcr-json-key

This is the status of the kit, build and Integration:

kubectl get it,ik,build
NAME                                         PHASE          READY   RUNTIME PROVIDER   RUNTIME VERSION   KIT   REPLICAS

And these are the final log messages from the operator:

I'll test with other default runtimes and let you know if the behavior changes.

[lsergio]

Using either runtime 3.8.1 or 3.15.0 as default doesn't change the results.

[lsergio]

Also, I have deleted all the Integration Kits and restarted the operator before each test.

[squakez]

Is there any warning condition in the Integration resource? Can you provide the -o yaml output of that?

[lsergio]

@squakez I did some investigation and have some interesting news:

I changed the operator log level to debug and with that I see these messages in the operator log:

Matching integration
Integration and integration-kit traits do not match
No match found between integration and integrationkit. Resetting integration's integrationkit to empty

I tracked the code and realized this happens when the Matches function on the CamelTrait returns false:

func (t *camelTrait) Matches(trait Trait) bool {
	otherTrait, ok := trait.(*camelTrait)
	if !ok {
		return false
	}
	return otherTrait.RuntimeVersion == t.RuntimeVersion
}

I added some debugging messages and found out that otherTrait.RuntimeVersion is "" and t.RuntimeVersion is "3.15.0", which is set as the default runtime at the Integration Platform.
If I add the runtimeVersion to my Integration, I see both variables match the value I set and the Integrations builds.

Also, I have eventually seen t.RuntimeVersion as 3.8.1, although I haven't identified the specific scenario. Trying to understand why, I found this function:

func determineRuntimeVersion(e *Environment) (string, error) {
	if e.Integration != nil && e.Integration.Status.RuntimeVersion != "" {
		return e.Integration.Status.RuntimeVersion, nil
	}
	if e.IntegrationKit != nil && e.IntegrationKit.Status.RuntimeVersion != "" {
		return e.IntegrationKit.Status.RuntimeVersion, nil
	}
	if e.IntegrationProfile != nil && e.IntegrationProfile.Status.Build.RuntimeVersion != "" {
		return e.IntegrationProfile.Status.Build.RuntimeVersion, nil
	}
	if e.Platform != nil && e.Platform.Status.Build.RuntimeVersion != "" {
		return e.Platform.Status.Build.RuntimeVersion, nil
	}
	return "", errors.New("unable to determine runtime version")
}

and decided to check the locations where it can get the runtime from.
Checking the IntegrationPlatform a see that e.Platform.Status.Build.RuntimeVersion is 3.8.1, even when the trait in the spec says 3.15.0. So that might be the reason I see 3.8.1 every now and then.

Here are the yamls for the platform:
