Red Hat OpenShift Development I: Introduction to Containers with Podman
Containers use a copy-on-write (COW) file system.
Containers use a thin runtime layer, which is ephemeral by default.
You can mount volumes and bind mounts to persist container data.
Some workloads, such as databases, might experience performance problems with the COW file system.
You can use Podman volumes to avoid using the COW file system.
