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:

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?

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 :

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

Can you paste the information about the inventory of components in the current cluster? The inventory file is located in the ~/.ofn/ directory by default, with a name such as *-inventory.yaml.

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)

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

@tpiperatgod ok , thanks very much for your time, the demo I will try it later . and let me try out shipwright-io, or maybe the issue is belongs shipwright-io.

Hi @aBreaking , you can join our community group chat 😄

@tpiperatgod ok , thanks very much for your time, the demo I will try it later . and let me try out shipwright-io, or maybe the issue is belongs shipwright-io.

Deleting Shipwright and then install it using ofn could solve the problem
