Where Is the Data Generated by a Container Stored If No Cloud Storage Is Mounted?

If no EVS disk or other cloud storage is mounted, the application data is stored in the physical machine disks of the container. Each pod can be allocated with a maximum of 20 GB disk of the CPU host or 20-GB disk of the GPU host for data storage. If the node is a dedicated node, the storage space can be adjusted based on customer requirements.

To ensure data security, the container engine obtains a virtual disk from devicemapper when creating a container. Other container engines cannot access the virtual disk of this container.
