Scheduler setup guide
This guide will walk you through the process of setting up the Scheduler service using a Docker image.
- MongoDB - version 4.4 or higher for storing taxonomies and contents
- Kafka - version 2.8 or higher
- MongoDB database
- ability to connect to a Kafka instance used by the engine
The service comes with most of the needed configuration properties filled in, but there are a few that need to be set up using some custom environment variables.
MongoDB helm example
Basic MongoDB configuration - helm values.yaml
This service needs to connect to a Mongo database that has replicas, in order to work correctly.
The MongoDB database is used to persist scheduled messages until they are sent back. The following configurations need to be set using environment variables:
SPRING_DATA_MONGODB_URI- the URI for the MongoDB database
The following Kafka related configurations can be set by using environment variables:
SPRING_KAFKA_BOOTSTRAP_SERVERS- address of the Kafka server
SPRING_KAFKA_CONSUMER_GROUP_ID- group of consumers
KAFKA_CONSUMER_THREADS- the number of Kafka consumer threads
KAFKA_AUTH_EXCEPTION_RETRY_INTERVAL- the interval between retries after
AuthorizationExceptionis thrown by
Each action available in the service corresponds to a Kafka event. A separate Kafka topic must be configured for each use-case.
Make sure the topics configured for this service don't follow the engine pattern.
The following environment variables could be set in order to control log levels:
LOGGING_LEVEL_ROOT- root spring boot microservice logs
LOGGING_LEVEL_APP- app level logs
