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

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

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"

apiVersion: core.openfunction.io/v1alpha2
kind: Function

spec:
  version: "v1.0.0"
  image: "openfunctiondev/sample-go-func:v0.5"

    builder: openfunction/builder-go:v0.4.0-1.15
    env:
      FUNC_NAME: "HelloWorld"

      revision: "release-0.5"

@tpiperatgod hi , i can apply yaml successful, but the BUILDSTATE of function-sample is UndefinedParameter, see:

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

[tpiperatgod]

and could you pls paste the details of the builds.shipwright.io resource builder-gjkgr-build-8zd57?

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

The components in your cluster look correct, can you delete the function and apply the following configuration? Pls let me know if this works properly...

apiVersion: core.openfunction.io/v1alpha2
kind: Function
metadata:
  name: function-demo
spec:
  version: "v1.0.0"
  image: "abreaking/sample-go-func:v0.5"
  imageCredentials:
    name: push-secret
  port: 8080
  build:
    builder: openfunction/builder-go:v0.4.0-1.15
    env:
      FUNC_NAME: "HelloWorld"
      FUNC_TYPE: "http"
    srcRepo:
      revision: "release-0.5"
      url: "https://github.com/OpenFunction/samples.git"
      sourceSubPath: "functions/Knative/hello-world-go"
  serving:
    runtime: Knative

@tpiperatgod unfortunately, still the same error 😶

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)
