Кажется, у меня проблема с развертыванием rook ceph в кластере k8s на fedora-coreos. Я надеюсь, что кто-то может помочь мне решить проблему, у меня есть Google, но я не могу найти решение для этого. Ниже мой кластер ямл и ошибка. Я использовал стандартные common.yaml и operator.yaml перед развертыванием пользовательского cluster.yaml. Спасибо
cluster-h2.yaml:
#################################################################################################################
# Define the settings for the rook-ceph cluster with common settings for a production cluster.
# All nodes with available raw devices will be used for the Ceph cluster. At least three nodes are required
# in this example. See the documentation for more details on storage settings available.
# For example, to create the cluster:
# kubectl create -f common.yaml
# kubectl create -f operator.yaml
# kubectl create -f cluster.yaml

# The container image used to launch the Ceph daemon pods (mon, mgr, osd, mds, rgw).
# v13 is mimic, v14 is nautilus, and v15 is octopus.
# RECOMMENDATION: In production, use a specific version tag instead of the general v14 flag, which pulls the latest release and could result in different
# versions running within the cluster. See tags available at https://hub.docker.com/r/ceph/ceph/tags/.
# If you want to be more precise, you can always use a timestamp tag such ceph/ceph:v14.2.5-20190917
# This tag might not contain a new Ceph version, just security fixes from the underlying operating system, which will reduce vulnerabilities
image: ceph/ceph:v14.2.8
