Openslice backend services are mainly implemented with Java 17 or above and Spring boot.

Openslice uses various subsystems and depending on the module would you like to work, other subsystems must be present (you can disable them though in the code, e.g. at application.yml file)

To get the latest development branch:

sudo ./ develop  [or replace develop with other branch name]


  • Slack:

General subsystems

  • Docker and Docker Compose should be installed in your development environment


consul service registry should be up and running. You can launch consul with docker: sudo docker run -d --name consul -p 8500:8500 -p 8600:8600 consul


ActiveMQ is our messaging system. You can launch an instance of ActiveMQ: sudo docker run --name='activemq' -d -e 'ACTIVEMQ_NAME=amqp-srv1' -e 'ACTIVEMQ_REMOVE_DEFAULT_ACCOUNT=true' -e 'ACTIVEMQ_ADMIN_LOGIN=admin' -e 'ACTIVEMQ_ADMIN_PASSWORD=admin' -e 'ACTIVEMQ_WRITE_LOGIN=producer_login' -e 'ACTIVEMQ_WRITE_PASSWORD=producer_password' -e 'ACTIVEMQ_READ_LOGIN=consumer_login' -e 'ACTIVEMQ_READ_PASSWORD=consumer_password' -e 'ACTIVEMQ_JMX_LOGIN=jmx_login' -e 'ACTIVEMQ_JMX_PASSWORD=jmx_password' -e 'ACTIVEMQ_STATIC_TOPICS=topic1;topic2;topic3' -e 'ACTIVEMQ_STATIC_QUEUES=queue1;queue2;queue3' -e 'ACTIVEMQ_MIN_MEMORY=1024' -e 'ACTIVEMQ_MAX_MEMORY=4096' -e 'ACTIVEMQ_ENABLED_SCHEDULER=true' -v /home/ctranoris/testcompose/data/activemq:/data/activemq -v /var/log/activemq:/var/log/activemq -p 8161:8161 -p 61616:61616 -p 61613:61613 webcenter/activemq:5.14.3

MySQL server

We use mysql as a storage DB. Please make sure that you have it installed in your system. There are instructions on internet how to install it. Check also our docker-compose installation script

Oauth server

Keycloak is used as the authentication server.

Note: Please check the Post installation steps -> Keycloak at localhost, at Deployment/Installation, if you are developing in a local environment
