Fail to install tf-operator in minikube because of the version of kubectl/kustomize

[pingsutw]

Try to use kubectl kustomize "github.com/kubeflow/tf-operator.git/manifests/overlays/standalone?ref=master" | kubectl apply -f - to install tf-oepator, and I met below erorr

(base) ➜  overlays git:(master) kubectl kustomize "github.com/kubeflow/tf-operator.git/manifests/overlays/standalone?ref=master" | kubectl apply -f -

Error: rawResources failed to read Resources: Load from path ../../base failed: '../../base' must be a file (got d='/tmp/kustomize-102836278/manifests/base')

Thanks for the issue, we will have a look asap

Cannot reproduce it here.

I am using 1.21, maybe I should try 1.19

[pingsutw]

I also try 1.16, 1,17. Both versions don't work for me.

@gaocegege It's not related to the Kubernetes version.
Upgrading kubectl to v1.21.0 solved the issue.

Refer to https://stackoverflow.com/questions/67071962/kubectl-apply-k-throws-error-rawresources-failed-to-read-resources-load-from

[gaocegege]

Interesting. Maybe we should add doc for it.

The version of the kustomize in different kubectl varies. This is kind of tricky and we should probably consider the compatibility later

1.19
https://github.com/kubernetes/kubernetes/blob/3e061debee7ceed92b2bf15a3b472c603e206b0c/go.mod#L141

1.20
https://github.com/kubernetes/kubernetes/blob/b9d77cc50b8d24422f2018ebe5b63e1d1b94236b/go.mod#L535

I didn't notice 1.19 and 1.20 are still using kustomize v2.0.x. The major reason kustomize doesn't work is only bases can refer to outside paths. See more details here. kubernetes-sigs/kustomize#776 (comment)
