Enum google_api_proto::google::container::v1beta1::workload_metadata_config::NodeMetadata

#[repr(i32)]
pub enum NodeMetadata {
    Unspecified = 0,
    Secure = 1,
    Expose = 2,
    GkeMetadataServer = 3,
}

NodeMetadata is the configuration for if and how to expose the node metadata to the workload running on the node.

Variants

Unspecified = 0

Not set.

Secure = 1

Prevent workloads not in hostNetwork from accessing certain VM metadata, specifically kube-env, which contains Kubelet credentials, and the instance identity token.

Metadata concealment is a temporary security solution available while the bootstrapping process for cluster nodes is being redesigned with significant security improvements. This feature is scheduled to be deprecated in the future and later removed.

Expose = 2

Expose all VM metadata to pods.

GkeMetadataServer = 3

Run the GKE Metadata Server on this node. The GKE Metadata Server exposes a metadata API to workloads that is compatible with the V1 Compute Metadata APIs exposed by the Compute Engine and App Engine Metadata Servers. This feature can only be enabled if Workload Identity is enabled at the cluster level.

Implementations

impl NodeMetadata

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of NodeMetadata.

pub fn from_i32(value: i32) -> Option<NodeMetadata>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a NodeMetadata, or None if value is not a valid variant.

impl NodeMetadata

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for NodeMetadata

fn clone(&self) -> NodeMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeMetadata

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

Formats the value using the given formatter.

impl Default for NodeMetadata

fn default() -> NodeMetadata

Returns the “default value” for a type.

impl From<NodeMetadata> for i32

fn from(value: NodeMetadata) -> i32

Converts to this type from the input type.

impl Hash for NodeMetadata

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NodeMetadata

fn cmp(&self, other: &NodeMetadata) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NodeMetadata

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for NodeMetadata

fn partial_cmp(&self, other: &NodeMetadata) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for NodeMetadata

type Error = UnknownEnumValue

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<NodeMetadata, UnknownEnumValue>

Performs the conversion.

impl Copy for NodeMetadata

impl Eq for NodeMetadata

impl StructuralPartialEq for NodeMetadata
