Enum UsernsModeArg 

pub enum UsernsModeArg {
    NoMap,
    KeepId,
    Auto,
}

Rootless user-namespace mapping strategy (--userns).

Docker/Podman-compatible names for the mapping written via /etc/subuid.

Variants

NoMap

Map container root (0) to the calling user only. Historic Nucleus behavior; workloads that refuse euid 0 (e.g. PostgreSQL) cannot run.

KeepId

Map the calling user’s uid/gid to itself; container root maps into the delegated subuid range (Podman --userns=keep-id). Recommended for bind-mounted host files owned by the user.

Auto

Map container root to the calling user and 1..N into the subuid range (Podman/Docker rootless default). Workloads run as their image uid.

Trait Implementations

impl Clone for UsernsModeArg

fn clone(&self) -> UsernsModeArg

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for UsernsModeArg

impl Debug for UsernsModeArg

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UsernsModeArg

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UsernsModeArg

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for UsernsModeArg

impl PartialEq for UsernsModeArg

fn eq(&self, other: &UsernsModeArg) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UsernsModeArg

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for UsernsModeArg

impl ValueEnum for UsernsModeArg

fn value_variants<'a>() -> &'a [Self]

All possible argument values, in display order.

fn to_possible_value<'a>(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
