红帽全球峰会第 4 章 Using persistent storage
Managing storage is a distinct problem from managing compute resources. MicroShift uses the Kubernetes persistent volume (PV) framework to allow node administrators to provision persistent storage for a node. Developers can use persistent volume claims (PVCs) to request PV resources without having specific knowledge of the underlying storage infrastructure.
You can use security context constraints (SCCs) to control permissions for the pods in your node. These permissions determine the actions that a pod can perform and what resources it can access. You can use SCCs to define a set of conditions that a pod must run with to be accepted into the system.
For more information see Managing security context constraints.
Only RWO volume mounts are supported. SCC could be blocked if pods are not operating with the SCC contexts.
