A rootless Podman container needs to access a host directory. Due to user namespace mapping, file ownership appears different inside the container. Which flag can be added to the mount to adjust UID/GID mapping behavior if supported?

Trap 1: podman run -v /host/path:/container/path:ns

'ns' is not a volume mount flag.

Trap 2: podman run -v /host/path:/container/path:uid=root

uid=root is not a valid suffix option.

Trap 3: podman run -v /host/path:/container/path:map

'map' is not a valid volume suffix flag.

A
podman run -v /host/path:/container/path:ns
Why wrong: 'ns' is not a volume mount flag.
B
podman run -v /host/path:/container/path:uid=root
Why wrong: uid=root is not a valid suffix option.
C
podman run -v /host/path:/container/path:U
The 'U' flag recursively changes ownership of the volume to match the user running the container.
D
podman run -v /host/path:/container/path:map
Why wrong: 'map' is not a valid volume suffix flag.

A rootless Podman container needs to access a host directory. Due to user namespace mapping, file ownership appears different inside the container. Which flag can be added to the mount to adjust UID/GID mapping behavior if supported?

An administrator runs a container with a SELinux-relabeled host directory mount using the Z option, but multiple containers need to share write access to this exact same volume. Which option should be used instead?

An engineer needs to inspect the low-level configuration details, mount points, and driver options of a named volume named 'app_vol'. Which command provides this information in JSON format?

Where are Podman named volumes typically stored on the host file system by default for a non-root user?

A developer wants to mount a host directory into a container with read-only permissions to prevent accidental data modification. Which volume option flag achieves this?

An administrator needs to create a persistent storage area managed completely by Podman that does not rely on a specific host directory path. Which command should be used?

How can an administrator remove all unused, dangling Podman volumes that are not currently attached to any container?

A Podman secret named 'db_password' has been created. How is this secret made accessible inside a running container?

How can an administrator remove an existing Podman secret named 'old_secret'?

Which command lists all named volumes currently managed by Podman?

Which flag is used with 'podman run' to create an ephemeral, writable container layer scratchpad that is automatically destroyed when the container stops?

A container needs to read a secret named 'api_key' injected as a file at '/run/secrets/api_key'. What is the default destination path inside the container when mounting a secret without specifying a target?

An administrator wants to create a named volume using a specific volume driver instead of the default local driver. Which flag should be used with 'podman volume create'?

Which subcommand deletes one or more specific named volumes?
