[−][src]Struct bollard::service::TaskSpecPlacement
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.
