podman-system-reset - Reset storage back to initial state
podman system reset [options]
podman system reset removes all pods, containers, images and volumes.
This command must be run before changing any of the following fields in the containers.conf or storage.conf files: driver, static_dir, tmp_dir or volume_path.
podman system reset reads the current configuration and attempts to remove all of the relevant configurations. If the administrator modified the configuration files first, podman system reset might not be able to clean up the previous storage.
Do not prompt for confirmation
Print usage statement
If the user ran rootless containers without having the fuse-overlayfs program installed, podman defaults to the vfs storage in their home directory. If they want to switch to use fuse-overlay, they must install the fuse-overlayfs package. The user needs to reset the storage to use overlayfs by default. Execute podman system reset as the user first to remove the VFS storage. Now the user can edit the /etc/containers/storage.conf to make any changes if necessary. If the system's default was already overlay, then no changes are necessary to switch to fuse-overlayfs. Podman looks for the existence of fuse-overlayfs to use it when set in the overlay driver, only falling back to vfs if the program does not exist. Users can run podman info to ensure Podman is using fuse-overlayfs and the overlay driver.
