type Trait

type Trait struct {
	traitv1.Trait `property:",squash" json:",inline"`
	// Enables automatic configuration of the trait.
	Auto *bool `property:"auto" json:"auto,omitempty"`
	// When this flag is active, the operator analyzes the source code to add dependencies required by delegate endpoints.
	// E.g. when using `master:lockname:timer`, then `camel:timer` is automatically added to the set of dependencies.
	// It's enabled by default.
	IncludeDelegateDependencies *bool `property:"include-delegate-dependencies" json:"includeDelegateDependencies,omitempty"`
	// Name of the configmap that will be used to store the lock. Defaults to "<integration-name>-lock".
	// Name of the configmap/lease resource that will be used to store the lock. Defaults to "<integration-name>-lock".
	ResourceName *string `property:"resource-name" json:"resourceName,omitempty"`
	// Type of Kubernetes resource to use for locking ("ConfigMap" or "Lease"). Defaults to "Lease".
	ResourceType *string `property:"resource-type" json:"resourceType,omitempty"`
	// Label that will be used to identify all pods contending the lock. Defaults to "camel.apache.org/integration".
	LabelKey *string `property:"label-key" json:"labelKey,omitempty"`
	// Label value that will be used to identify all pods contending the lock. Defaults to the integration name.
	LabelValue *string `property:"label-value" json:"labelValue,omitempty"`

The Master trait allows to configure the integration to automatically leverage Kubernetes resources for doing leader election and starting *master* routes only on certain instances.

It's activated automatically when using the master endpoint in a route, e.g. `from("master:lockname:telegram:bots")...`.

NOTE: this trait adds special permissions to the integration service account in order to read/write configmaps and read pods. It's recommended to use a different service account than "default" when running the integration.
