The problem was the line below. When I removed trafficRouting, the pod was deployed. Why is that?

trafficRouting:
  plugins:
    argoproj-labs/gatewayAPI:
      httpRoute: argo-rollouts-http-route # our created httproute
      namespace: foobar

Hello

The part that you mention is the part that loads the plugin. And the error you posted shows that the plugin is not loaded.

Possible reasons:

  1. The clusters doesn't have access to the URL you have defined for the plugin
  2. You are trying to load the plugin of a different architecture.

Have you also followed https://rollouts-plugin-trafficrouter-gatewayapi.readthedocs.io/en/latest/installation/ ?

Can you post the argo-rollouts-config please and also mention what type of machine is running Argo Rollouts?

Also the plugin you are trying to load is the latest one for Kubernetes API gateway 1.0+ Are you sure the version of Istio you are running also supports this version?

oliverpark999 commented 6 days ago

Hi!

When I configured the plugin with v0.3.0, the plugin was loaded normally and Replicas also worked.

But here's my question.

My k8s Gateway API is version 1.0.

So all resources are already using gateway.networking.k8s.io/v1.

However, in version v0.4.0, an error message was printed and it did not work properly,

but in version v0.3.0, it worked normally.

Do you know anything about this?

oliverpark999 commented 6 days ago

I read the release notes and it seems that k8s Gateway API v1.0 is supported starting from v0.3.0. Then, is this a bug in v0.4.0?

Philipp-Plotnikov commented 6 days ago

Can you say machine architecture and the plugin that you are trying to download, please ?

oliverpark999 commented 5 days ago

Yes, The hardware architecture of my Kubernetes Node server is x86, and the plugin that caused the error message is gatewayapi-plugin-linux-amd64(v0.4.0).

kostis-codefresh commented 5 days ago

My k8s Gateway API is version 1.0.

What is your Istio version?

When I configured the plugin with v0.3.0, the plugin was loaded normally and Replicas also worked.

But did you enable again the plugin in the Rollout? Because previously you said you removed that part

trafficRouting:
  plugins:
    argoproj-labs/gatewayAPI:
      httpRoute: argo-rollouts-http-route # our created httproute
      namespace: foobar

To the best of my knowledge there are no major API changes between plugin 0.3.0 and 0.4.0

oliverpark999 commented 4 days ago

Istio is version 1.22.3. As you said, I removed trafficRouting and checked that it works. However, I tried several things without stopping the game. That was v0.3.0, and I added trafficRouting again. I also restarted Argo-Rollout Deployment. The result was normal operation as below.
