Fields

constraints: Option<Vec<String, Global>>

An array of constraint expressions to limit the set of nodes where a task can be scheduled. Constraint expressions can either use a match (==) or exclude (!=) rule. Multiple constraints find nodes that satisfy every expression (AND match). Constraints can match node or Docker Engine labels as follows:

node attribute	matches	example
node.id	Node ID	node.id==2ivku8v2gvtg4
node.hostname	Node hostname	node.hostname!=node-2
node.role	Node role (manager/worker)	node.role==manager
node.platform.os	Node operating system	node.platform.os==windows
node.platform.arch	Node architecture	node.platform.arch==x86_64
node.labels	User-defined node labels	node.labels.security==high
engine.labels	Docker Engine’s labels	engine.labels.operatingsystem==ubuntu-14.04

engine.labels apply to Docker Engine labels like operating system, drivers, etc. Swarm administrators add node.labels for operational purposes by using the node update endpoint.

max_replicas: Option<i64>

Maximum number of replicas for per node (default value is 0, which is unlimited)

platforms: Option<Vec<Platform, Global>>

Platforms stores all the platforms that the service’s image can run on. This field is used in the platform filter for scheduling. If empty, then the platform filter is off, meaning there are no scheduling restrictions.

preferences: Option<Vec<TaskSpecPlacementInlineItemPreferencesInlineItem, Global>>

Preferences provide a way to make the scheduler aware of factors such as topology. They are provided in order from highest to lowest precedence.

Trait Implementations

impl Clone for TaskSpecPlacementInlineItem

fn clone(&self) -> TaskSpecPlacementInlineItem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TaskSpecPlacementInlineItem

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskSpecPlacementInlineItem

fn deserialize<__D>(
    __deserializer: __D
) -> Result<TaskSpecPlacementInlineItem, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl PartialEq<TaskSpecPlacementInlineItem> for TaskSpecPlacementInlineItem

fn eq(&self, other: &TaskSpecPlacementInlineItem) -> 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 Serialize for TaskSpecPlacementInlineItem

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

Serialize this value into the given Serde serializer.
