It seems that Kong will have an implementation for the Kubernetes Gateway API https://gateway-api.sigs.k8s.io/implementations/#kong

So Kong support might be available after implementing #1438

[borkke]

I found out about this open issue only after we did the implementation where we have Kong as ingress controller (without Kuma) and our services are deployed with:

• service
• service-preview
• ingress
• ingress-preview
• rollout (tested canary and blue-green)
• and hpa

I was very surprised when I saw that Kong is not on the supported list but my setup works perfectly fine. So, I'm wondering am I missing something here?

I was even able to run canary and blue-green example first with Nginx being my ingress then I just switched to Kong ingress and it worked fine.

• kong -> 2.7.0
• rollouts -> 1.1.0

@borkke Do you mind sharing an example of how you got it all set up, please? I'm making research if this is a viable option as of today and it would help a lot to have something to look at. Thanks

Here are few notes what I did:

• Used minikube
• Enabled nginx ingress using minikube minikube addons enable ingress
• Checked out rollouts-demo
• Added all URLs to my host file (canary.dev.argoproj.io, canary-preview.dev.argoproj.io, blue-green-preview.dev.argoproj.io, blue-green.dev.argoproj.io) to point to my minikube instance
• tried these two examples blue/green and canary

The examples worked fine. Then I uninstalled nginx ingress and installed Kong ingress and everything worked fine as before. This should be enough I think:

minikube addons disable ingress
helm install kong kong/kong --set proxy.type=NodePort

I tried canary example and it worked just fine. This is the only diff that I have locally:

I did have small issue and I think it's probably my local Kong configuration. The Location HTTP header was not picked up and I worked around this by using Header Editor and with that the example worked as expected.

Also, we currently have ArgoCD/Rollout/Kong on EKS with working canary and blue/green deployments.

@mykyta-batalov Just checking in... Did you have any progress regarding this?

[PhilippPlotnikov]

Hi, I have implemented Gateway API support. Can someone review it ?
#2004
It should solve the problem with Kong and Kuma

[github-actions]

This issue is stale because it has been open 60 days with no activity.

[lucasoarruda]
