Enum PullPolicy 

pub enum PullPolicy {
    Always,
    Build,
    Daily,
    Missing,
    Never,
    Refresh,
    Weekly,
    Other(String),
}

Defines the decisions Compose makes when it starts to pull images.

See more: https://docs.docker.com/reference/compose-file/services/#pull_policy

Variants

Always

Compose always pulls the image from the registry.

Build

Compose builds the image. Compose rebuilds the image if it’s already present.

Daily

Compose checks the registry for image updates if the last pull took place more than 24 hours ago.

Missing

Compose pulls the image only if it’s not available in the platform cache. This is the default option if you are not also using the Compose Build Specification. if_not_present is considered an alias for this value for backward compatibility. The latest tag is always pulled even when the missing pull policy is used.

Never

Compose doesn’t pull the image from a registry and relies on the platform cached image. If there is no cached image, a failure is reported.

Refresh

Weekly

Compose checks the registry for image updates if the last pull took place more than 7 days ago.

Trait Implementations

impl Clone for PullPolicy

fn clone(&self) -> PullPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PullPolicy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PullPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PullPolicy

fn eq(&self, other: &PullPolicy) -> 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 PullPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PullPolicy
