I tried to run go mod tidy (and to remove it manually) but somehow I was not able to remove this import:
$ go mod tidy
go: finding module for package sigs.k8s.io/sig-storage-lib-external-provisioner/controller/metrics

thanks for this PR, the main topic for v.1.13.0 is fixing all the storage provsioiner legacy debt, and this is a good start.
for this this PR to be tested, we would need to rebuild the Dockerfile and make sure it still works
do you mind building the storage docker file locally and test it locally and paste the output of it with the new storage provisioners?

Hm, the failures seem unrelated to me. Is there a way to retrigger them? |

Hey @johscheuer I think the test failures are unrelated -- this LGTM |

This PR updates the https://sigs.k8s.io/sig-storage-lib-external-provisioner to version v5.0.0 to support Kubernetes 1.18 properly (1.18 support was introduces in
5.0.0). The new version of the lib automatically tries to use leader-election, I added an extraRole+RoleBindingfor the RBAC. For the most use-cases the old version will work but if a controller/operator changes thePVCobject the storage provisioner will fail with the following error message:E0630 10:20:08.514160 1 reflector.go:205] k8s.io/minikube/vendor/github.com/r2d4/external-storage/lib/controller/controller.go:411: Failed to list *v1.PersistentVolumeClaim: v1.PersistentVolumeClaimList: Items: []v1.PersistentVolumeClaim: v1.PersistentVolumeClaim: ObjectMeta: v1.ObjectMeta: readObjectFieldAsBytes: expect :kubectl get storageclassng 912 ...:{},"k:{\"... at {"kind":"PersistentVolumeClaimList","apiVersion":"v1","metadata":{"selfLink":"/api/v1/persistentvolumeclaims","resourceVersion":"1509"},"items":[{"metadata":{"name":"controller-sqlite","namespace":"default","selfLink":"/api/v1/namespaces/default/persistentvolumeclaims/controller-sqlite","uid":"95f218fc-6cee-4fc0-99e7-d0508f698ede","resourceVersion":"1509","creationTimestamp":"2020-06-30T10:15:54Z","annotations":{"volume.beta.kubernetes.io/storage-provisioner":"k8s.io/minikube-hostpath"},"ownerReferences":[{"apiVersion":"iofog.org/v2","kind":"ControlPlane","name":"iofog","uid":"13202d97-bd76-4a01-ba58-c9a0cf43ff21","controller":true,"blockOwnerDeletion":true}],"finalizers":["kubernetes.io/pvc-protection"],"managedFields":[{"manager":"iofog-operator","operation":"Update","apiVersion":"v1","time":"2020-06-30T10:15:54Z","fieldsType":"FieldsV1","fieldsV1":{"f:metadata":{"f:ownerReferences":{".":{},"k:{\"uid\":\"13202d97-bd76-4a01-ba58-c9a0cf43ff21\"}":{".":{},"f:apiVersion":{},"f:blockOwnerDeletion":{},"f:controller":{},"f:kind":{},"f:name":{},"f:uid":{}}}},"f:spec":{"f:accessModes":{},"f:resources":{"f:requests":{".":{},"f:storage":{}}},"f:volumeMode":{}},"f:status":{"f:phase":{}}}},{"manager":"kube-controller-manager","operation":"Update","apiVersion":"v1","time":"2020-06-30T10:15:54Z","fieldsType":"FieldsV1","fieldsV1":{"f:metadata":{"f:annotations":{".":{},"f:volume.beta.kubernetes.io/storage-provisioner":{}}}}}]},"spec":{"accessModes":["ReadWriteOnce"],"resources":{"requests":{"storage":"1Gi"}},"storageClassName":"standard","volumeMode":"Filesystem"},"status":{"phase":"Pending"}}]}With the new version of the lib everything works as expected.
