Manual Deployment

The installation works under Windows, Linux and macOS. The only dependency is an installed OpenJDK 11 or 17 with 17 recommended. Blaze is tested with Eclipse Temurin.

Blaze runs on the JVM and comes as single JAR file. Download the most recent version here. Look for blaze-0.20.6-standalone.jar.

After the download, you can start blaze with the following command (Linux, macOS):

java -jar blaze-0.20.6-standalone.jar

Blaze will run with an in-memory, volatile database for testing and demo purposes.

Blaze can be run with durable storage by setting the environment variables STORAGE to standalone.

Under Linux/macOS:

STORAGE=standalone java -jar blaze-0.20.6-standalone.jar

Under Windows, you need to set the Environment variables in the PowerShell before starting Blaze:

$Env:STORAGE="standalone"
java -jar blaze-0.20.6-standalone.jar

This will create three directories called index, transaction and resource inside the current working directory, one for each database part used.

The output should look like this:

In order to test connectivity, query the health endpoint:

curl http://localhost:8080/health

After that please note that the FHIR RESTful API is available under http://localhost:8080/fhir. A good start is to query the CapabilityStatement of Blaze using jq to select only the software key of the JSON output:

curl -H 'Accept:application/fhir+json' -s http://localhost:8080/fhir/metadata | jq .software

that should return:

{
  "name": "Blaze",
  "version": "0.20.6"
}

Blaze will be configured through environment variables which are documented here.
