Seyren API

See Seyren API


You can use Seyren Cookbook to deploy Seyren with Chef.


You can use the Docker Seyren Image to deploy a seyren instance in a docker container.

Init script

Seyren-Init is an init.d script which allows you to start the service.


Build Status

To run the acceptance tests with Maven:

mvn clean verify

To run the integration tests with Maven:

mvn clean verify -Pkarma

To fire-up the app using Maven and wait (meaning you can run the tests separately from your IDE):

mvn clean verify -Dwait

You should then be able to browse to http://localhost:8080/seyren and have a play.

To package up a new jar file without running the tests:

mvn package -DskipTests
# Set environment variables as needed.
java -jar seyren-web/target/seyren-web-*-war-exec.jar
