CMO Label Generator 🔍

CMO Label Generator is a distributed microservices system. It receives messages from LIMS when a request is marked delivered. This message is processed and a unique CMO label Id is generated based on specifications that can be found in CMOPatientIDandSampleIDgeneration.pdf. Any new message is then published to downstream subscribers. The message published is a JSON reqpresentation of SmileRequest (more details can be found in smile-server repository).

Label Generator is dependent on SMILE, Nats Jetstream and Nats RequestReply.

Run

Custom properties

Make an application.properties based on application.properties.EXAMPLE.

Nats Pub/Sub topics:

• igo.cmo_label_generator_topic : receives requests to process
• request_reply.patient_samples_topic : used to patient samples set from SMILE Server
• igo.new_request_topic : publishes the processed request to this topic

All properties are required with the exception of some NATS connection-specific properties. The following are only required if nats.tls_channel is set to true:

Nats Connection props:

• nats.keystore_path : path to client keystore
• nats.truststore_path : path to client truststore
• nats.key_password : keystore password
• nats.store_password : truststore password

Locally

Requirements:

• maven 3.6.1
• java 8

Add application.properties to the local application resources: src/main/resources

Build with

mvn clean install

Run with

java -jar server/target/smile_label_generator.jar

With Docker

Requirements

• docker

Build image with Docker

docker build -t <repo>/<tag>:<version> .

Push image to DockerHub

docker push <repo>/<tag>:<version>

If the Docker image is built with the properties baked in then simply run with:

docker run --name cmo-label-generator <repo>/<tag>:<version> \
	-jar /label-generator/smile_label_generator.jar

Otherwise use a bind mount to make the local files available to the Docker image and add --spring.config.location to the java arg

docker run --mount type=bind,source=<local path to properties files>,target=/label-generator/src/main/resources \
	--name label-generator <repo>/<tag>:<version> \
	-jar /label-generator/smile_label_generator.jar \
	--spring.config.location=/label-generator/src/main/resources/application.properties
