You will want to edit the tomcat section, and add something like this:

- CATALINA_OPTS=-DIRIUS_SESSION_TIME_OUT=720

    tomcat:
        environment:
            - IRIUS_DB_URL=jdbc\:postgresql\://172.17.0.1\:5432/iriusprod?user\=iriusprod&password\=*****************
            - IRIUS_EDITION=saas
            - IRIUS_EXT_URL=https\://youririusriskendpoint.com
            - grails_env=production
            - STARTLEFT_URL=http://startleft:8081/api/v1/startleft/iac
            - CATALINA_OPTS=-DIRIUS_SESSION_TIME_OUT=720
        image: continuumsecurity/iriusrisk-prod:tomcat-4
        container_name: iriusrisk-tomcat
        networks:
            - iriusrisk-frontend
            - iriusrisk-backend
        mem_reservation: 2G
        cpu_shares: 1024

The value (720) is in minutes.
