Fields

constraints: Option<Vec<String>>

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.

preferences: Option<Vec<TaskSpecPlacementPreferences>>

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

max_replicas: Option<i64>

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

platforms: Option<Vec<Platform>>

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.

Trait Implementations

impl Clone for TaskSpecPlacement

fn clone(&self) -> TaskSpecPlacement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TaskSpecPlacement

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

Formats the value using the given formatter.

impl Default for TaskSpecPlacement

fn default() -> TaskSpecPlacement

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TaskSpecPlacement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TaskSpecPlacement

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

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.
