[kubebuilder] `sh: controller-gen: command not found`

[katt-999]

Hello,

While using kubebuilder extension, I've encountered that issue :

local: which kubebuilder
 → /opt/homebrew/bin/kubebuilder
kubebuilder is present: /opt/homebrew/bin/kubebuilder

local: controller-gen rbac:roleName=manager-role crd webhook paths="./..." output:crd:artifacts:config=config/crd/bases;controller-gen object:headerFile="hack/boilerplate.go.txt" paths="./...";
 → sh: controller-gen: command not found
 → sh: controller-gen: command not found
Traceback (most recent call last):
  /Users/<anon-data>/development/kubernetes/<anon-data>/test-operator/Tiltfile:91:12: in <toplevel>
  /Users/<anon-data>/Library/Application Support/tilt-dev/tilt_modules/github.com/tilt-dev/tilt-extensions/kubebuilder/Tiltfile:55:10: in kubebuilder
Error in local: command "controller-gen rbac:roleName=manager-role crd webhook paths=\"./...\" output:crd:artifacts:config=config/crd/bases;controller-gen object:headerFile=\"hack/boilerplate.go.txt\" paths=\"./...\";" failed.
error: exit status 127

On my side, the problem come from the controller-gen binary is in current_path/bin :

On kubebuilder tiltfile, we can see controller-gen is invoked directly.

    def manifests():
        return 'controller-gen ' + CONTROLLERGEN

    def generate():
        return 'controller-gen object:headerFile="hack/boilerplate.go.txt" paths="./...";'

I tried this and it worked :

    def manifests():
        return 'bin/controller-gen ' + CONTROLLERGEN

    def generate():
        return 'bin/controller-gen object:headerFile="hack/boilerplate.go.txt" paths="./...";'

I don't know if that behaviour is specific to my environment, but maybe it can be great to if needed to specify the controller-gen binary path like :

def kubebuilder(DOMAIN, GROUP, VERSION, KIND, IMG='controller:latest', CONTROLLERGEN='rbac:roleName=manager-role crd webhook paths="./..." output:crd:artifacts:config=config/crd/bases;', DISABLE_SECURITY_CONTEXT=True, BIN_PATH=""):
...
    def manifests():
        return os.path.join(BIN_PATH, 'controller-gen ') + CONTROLLERGEN

    def generate():
        return os.path.join(BIN_PATH, 'controller-gen ') + 'object:headerFile="hack/boilerplate.go.txt" paths="./...";'
...   

So we can invoked kubebuilder like this and work like a charm 💫 :

kubebuilder('netbox.airnity.io', 'extras', 'v1alpha1', 'CustomField', BIN_PATH="bin/") 

Also, I don't work with kubebuilder directly, but with operator-sdk, maybe that plugin can also have a compability by using 'operator-sdk' commands instead of 'kubebuilder' (args seems the same)

Cheers, Guillaume
