27.15.3. 배포 예

CSI 구성 요소가 실행될 새 프로젝트와 구성 요소를 실행할 새 서비스 계정을 생성합니다. 명시적 노드 선택기는 마스터 노드에서도 CSI 드라이버와 함께 Daemonset을 실행하는 데 사용됩니다.

# oc adm new-project csi --node-selector=""
Now using project "csi" on server "https://example.com:8443".

# oc create serviceaccount cinder-csi
serviceaccount "cinder-csi" created

# oc adm policy add-scc-to-user privileged system:serviceaccount:csi:cinder-csi
scc "privileged" added to: ["system:serviceaccount:csi:cinder-csi"]

이 YAML 파일을 적용하여 CSI 드라이버와 함께 외부 CSI 연결 및 프로비저너 및 DaemonSet을 사용하여 배포를 생성합니다.

# This YAML file contains all API objects that are necessary to run Cinder CSI
# driver.
#
# In production, this needs to be in separate files, e.g. service account and
# role and role binding needs to be created once.
#
# It serves as an example of how to use external attacher and external provisioner
# images that are shipped with OpenShift Container Platform with a community CSI driver.
