Engine

Engine Properties describes the configuration options available in the MATRIXX Engine sub-chart.

Table 1. Engine Properties
Property	Description
engine.connections.activemq.host	The host name to use when connecting to ActiveMQ. The default value is `activemq-1`.
engine.connections.activemq.port	The port to use when connecting to ActiveMQ. The default value is `61616`.
engine.remoteConfigurationUrl	(Optional) The URL from which Engine configuration can be downloaded at start-up.
engine.serviceAnnotations.processing	A dictionary of annotations added to the TCP and UPD Services created for the Engine Processing Service. The value for each annotation can include resolvable Helm expressions. For more information, see the discussion about annotations in Kubernetes documentation. Note: These annotations are only used by the Service templates for the Engine Operator due to certain limitations. These may be removed in a future release in favor of the `global.topology.domains[x].subdomains[y].engines[z].processing.serviceAnnotations` property.
engine.serviceAnnotations.publishing	A dictionary of annotations added to the TCP and UPD Services created for the Engine Publishing Service. The value for each annotation can include resolvable Helm expressions. For more information, see the discussion about annotations in Kubernetes documentation. Note: These annotations are only used by the Service templates for the Engine Operator due to certain limitations. These might be removed in a future release in favor of the `global.topology.domains[x].subdomains[y].engines[z].publishing.serviceAnnotations` property.
engine.serviceAnnotations.checkpointing	A dictionary of annotations added to the TCP and UPD Services created for the Engine Checkpointing Service. The value for each annotation can include resolvable Helm expressions. For more information, see the discussion about annotations in Kubernetes documentation. Note: These annotations are only used by the Service templates for the Engine Operator due to certain limitations. These might be removed in a future release in favor of the `global.topology.domains[x].subdomains[y].engines[z].checkpointing.serviceAnnotations` property.
engine.podAnnotations.processing	A dictionary of annotations added to the Engine Processing StatefulSet Pod(s). The value for each annotation can include resolvable Helm expressions. For more information, see the discussion about annotations in Kubernetes documentation. Note: These annotations are only used by the StatefulSet templates for the Engine Operator due to certain limitations. These might be removed in a future release in favor of the `global.topology.domains[x].subdomains[y].engines[z].processing.podAnnotations` property.
engine.podAnnotations.publishing	A dictionary of annotations added to the Engine Publishing StatefulSet Pod(s). For more information, see the discussion about annotations in Kubernetes documentation. Note: These annotations are only used by the StatefulSet templates for the Engine Operator due to certain limitations. These might be removed in a future release in favor of the `global.topology.domains[x].subdomains[y].engines[z].publishing.podAnnotations` property.
engine.podAnnotations.checkpointing	A dictionary of annotations added to the Engine Checkpointing StatefulSet Pod(s). The value for each annotation can include resolvable Helm expressions. For more information, see the discussion about annotations in Kubernetes documentation. Note: These annotations are only used by the StatefulSet templates for the Engine Operator due to certain limitations. These might be removed in a future release in favor of the `global.topology.domains[x].subdomains[y].engines[z].checkpointing.podAnnotations` property.
engine.mongodb.connectionString	(Optional) Overrides the value of `global.mongodb.connectionString` for MATRIXX Engine. In multi-tenant deployments, if no value is specified for the `global.topology.domains[x].tenants[n].mongodb.connectionString` property, the value specified for this property is used. If neither `global.topology.domains[x].tenants[n].mongodb.connectionString` or this property is configured, the value of `global.mongodb.connectionString` is used.
operator.manager.nolbCheck	Set to `true` so that the Engine Operator does not wait indefinitely in situations where IP addresses are never assigned for load balancers, for example, in cases where the load balancer controller architecture routes traffic directly to the pods. The default value is `false`.
