Container volume information

The items provided in Container Volume are as follows:

ContainerIdContainer ID, a unique identifier for the container. This ID is generated by the container runtime. It is required to identify and manage containers within a cluster.
Pod NameName of the Pod to which the container belongs. In a Kubernetes cluster, multiple containers can run within a Pod. Using the name, it is possible to identify which Pod the container belongs to.
MountTypeVolume-mounted type. However, because tmpfs is a temporary file system that uses memory, it is not displayed in the corresponding Container Volume list.
-bind: It means that a specific directory is mounted on the host.
-volume: It means that a specific file system (e.g. /var/lib/docker/volumes/) managed by Docker is mounted on the host.
SourcePath to the volume on the host. This path indicates where the volume is physically stored.
DriverThis volume driver is used when creating the volume. It determines how to store the data and manage the volume. Currently, this information is primarily provided by the Docker in runtime. Lower-level container runtimes such as containerd and CRI-O do not directly provide these high-level information details. The monitoring dashboard provides a limited amount of volume data through the runtime API.
MountThe path where the volume has been mounted within the container. This path allows the applications within the container to access the data stored on the volume.
Total(Byte)The total capacity of the volume in bytes. This indicates the maximum amount of data that can be stored on the volume.
Used(Byte)The amount of capacity in bytes in use on the volume. This indicates the amount of data stored on the volume.
UsedPercentThe utilization of volume capacity in percentage. This ratio shows the percentage of capacity in use compared to the volume's total capacity. Higher utilization means the volume is running out of space. This can be an important metric for poor performance or risk of data loss.
