When I try to setup kubeflow with minikube on my local desktop(Ubuntu 20.0.4) and run kubectl create -f bootstrapper.yaml according to this official document, I got the AlreadyExists following error.

Error from server (AlreadyExists): error when creating
"bootstrapper.yaml": namespaces "kubeflow-admin" already exists Error
from server (AlreadyExists): error when creating "bootstrapper.yaml":
persistentvolumeclaims "kubeflow-ksonnet-pvc" already exists [unable
to recognize "bootstrapper.yaml": no matches for kind
"ClusterRoleBinding" in version "rbac.authorization.k8s.io/v1beta1",
unable to recognize "bootstrapper.yaml": no matches for kind
"StatefulSet" in version "apps/v1beta2"]

After deleting namespace and persistent volume and run the same command, then I got this version error messages.

namespace/kubeflow-admin created
persistentvolumeclaim/kubeflow-ksonnet-pvc created unable to recognize
"bootstrapper.yaml": no matches for kind "ClusterRoleBinding" in
version "rbac.authorization.k8s.io/v1beta1" unable to recognize
"bootstrapper.yaml": no matches for kind "StatefulSet" in version
"apps/v1beta2"

Thus, I changed versions for ClusterRoleBinding and StatefulSet to v1 according to this, then I got this error.

persistentvolumeclaim/kubeflow-ksonnet-pvc created
statefulset.apps/kubeflow-bootstrapper created Error from server
(AlreadyExists): error when creating "bootstrapper.yaml":
clusterrolebindings.rbac.authorization.k8s.io "kubeflow-cluster-admin"
already exists

So, I also delete the clusterrolebindings kubeflow-cluster-admin and rerun kubectl create -f bootstrapper.yaml. Then, I got expected result.

namespace/kubeflow-admin created
clusterrolebinding.rbac.authorization.k8s.io/kubeflow-cluster-admin created
persistentvolumeclaim/kubeflow-ksonnet-pvc created
statefulset.apps/kubeflow-bootstrapper created

I checked the existence of namespaces to be created by kubectl get ns, then

NAME                   STATUS   AGE
default                Active   8h
kube-node-lease        Active   8h
kube-public            Active   8h
kube-system            Active   8h
kubeflow-admin         Active   60s
kubernetes-dashboard   Active   8h

But, I got No resources found in kubeflow namespace. by kubectl -n kubeflow get svc

I already checked this post. I waited long but I don't get any results.

I run docker images then there is no gcr.io/kubeflow-images-public/bootstrapper:v0.2.0. Thus it seems bootstrap failed.

Summary

• This document is deprecated. I realized the version of this site was v0-2.

• I followed this Japanese document. hack/setup-kubeflow.sh is an installation tool. This is not mentioned in the kubeflow/manifests repository. This was the breakthrough for me.

• I read this document carefully. And I found the there was prerequisite for compatibility and tools I installed did not follow the requirements.

• Succeeded versions and branch I tried.

Ubuntu 20.0.4 minikube v1.26.1
kustomize v3.2.0
kubectl v1.21.14
kubeflow/manifests v1.6-branch
