Description Denis Ollier 2021-08-10 18:47:13 UTC 
Description of problem
----------------------

After creating a HostPathProvisioner CustomResource, the DaemonSet is created by the hostpath-provisioner-operator but hostpath-provisioner Pods are not created.

Analysis
--------

The hostpath-provisioner Pod template has been modified in upstream PR https://github.com/kubevirt/hostpath-provisioner-operator/pull/113.

Among other changes, the Pod is now privileged.

> kind: DaemonSet
> apiVersion: apps/v1
> metadata:
>   name: hostpath-provisioner
>   namespace: openshift-cnv
> spec:
>   [...]
>   template:
>     [...]
>     spec:
>       containers:
>         - name: hostpath-provisioner
>           [...]
>           securityContext:
>             privileged: true
>           [...]

However the SCC has not been updated to allow such privileges

> kind: SecurityContextConstraints
> apiVersion: security.openshift.io/v1
> metadata:
>   name: hostpath-provisioner
> [...]
> allowPrivilegedContainer: false
> [...]
> users:
> - system:serviceaccount:openshift-cnv:hostpath-provisioner-admin
> [...]

Modifying the SCC to allow privileged containers (after scaling down the hostpath-provisioner-operator) fixes the issue.

Version
-------
OCP: 4.9.0-0.nightly
CNV: http://cnv-version-explorer.apps.cnv.engineering.redhat.com/BundleDetails?ver=v4.9.0-89
Comment 1 Denis Ollier 2021-08-12 08:10:32 UTC 
Fixed upstream in https://github.com/kubevirt/hostpath-provisioner-operator/pull/123.

Verified with http://cnv-version-explorer.apps.cnv.engineering.redhat.com/BundleDetails?ver=v4.9.0-99.
Comment 2 Yan Du 2021-08-16 09:36:39 UTC 
The feature should be fully addressed in CNV 4.10, so change the version to 4.10
If the issue can not be reproduced on 4.10, feel free to close it.
Comment 3 Maya Rashish 2021-10-13 09:12:05 UTC 
Verified as already fixed in 4.9.0-99 by Denis Ollier. This means it's in 4.9.0 already.
Comment 4 Maya Rashish 2021-10-13 09:15:32 UTC 
Undoing previous, I didn't realize that cnv-4.9 went backwards and the breakage is now specific to 4.10 and should be fixed in 4.10.
Comment 5 Maya Rashish 2021-10-13 09:21:47 UTC 
Fix for v4.10.0 should be from hostpath-provisioner-operator v4.10.0-4.
