helloworld-go : no matches for kind "Function" in version "core.openfunction.io/v1beta1"

[aBreaking]

following hello-world-go, when i exec command

kubectl apply -f function-sample.yaml

An error occurred :

error: unable to recognize "function-sample.yaml": no matches for kind "Function" in version "core.openfunction.io/v1beta1"

can help me?

I just completely installed ofn. and the pods of ofn components were running that i have checked.

The following existing components will be skipped:
 - CertManager
 - IngressNginx
 - Dapr
 - Keda
 - Knative Serving
 - Tekton Pipelines
 - Shipwright
 ✓ Shipwright - Completed!
 ✓ OpenFunction - Completed!
🚀 Completed in 1m9.205258418s.

The ofn installs the latest stable version of OpenFunction (v0.5.0 for now) by default, with the branch of the corresponding sample as release-0.5.

Can you paste the contents of the functions-sample.yaml?

@tpiperatgod

functions-sample.yaml

apiVersion: core.openfunction.io/v1beta1
kind: Function
metadata:
 name: function-sample
spec:
 image: "abreaking/sample-go-func:latest"

and i also used official yaml , also same error occurred.

my minikube version:

minikube v1.23.1

pods of openfunction status is :

root@kube-PC:~# k get pods -n openfunction
NAME READY STATUS RESTARTS AGE
openfunction-controller-manager-5f55b55fcf-vhghn 2/2 Running 4 (15h ago) 18h

Hi, @aBreaking , you should use this yaml file: https://github.com/OpenFunction/samples/blob/release-0.5/functions/Knative/hello-world-go/function-sample.yaml

Note that spec.build.srcRepo.revision needs to be set to "release-0.5"

There should be an exception in the process of building the function image.

Could you please paste the details of the buildruns.shipwright.io resource?

For example:

kubectl get buildruns.shipwright.io

or

kubectl describe buildruns.shipwright.io <name>

If a build failed, the builder CR will be kept. Take a look at the build pod's log to find out the failure reason

Thx @aBreaking , but I still haven't found the exact reason 😂

[tpiperatgod]

OK, while I don't know what causes this exception in your cluster, the problem occurs for the following reason:

The OpenFunction controller creates the builds.shipwright.io resource when it builds the function, and there is an APP_IMAGE parameter (it was present in versions earlier than 0.5) in there that cannot be passed to clusterbuildstrategies.

I have not had this problem so far after verifying it in my cluster, so I can't be sure what is wrong with the configuration.

BUT! There is another way to get a taste of OpenFunction: you can use the ofn demo, like:
ofn demo --auto-prune=false (this command would save the demo env)

See more at: https://github.com/OpenFunction/cli/blob/main/docs/demo.md
