Connecting Kura to Kapua

In the past articles I independently sat up an Eclipse Kapua service using Docker containers and installed Eclipse Kura on a Raspberry Pi. Now its time to connect these and see what happens. Preparing Kapua At first, since Kapua is a multi-tenant installation, we need to create an organisation and an admin user in this […]

Creating a standalone instance of Eclipse Kapua using Docker containers

Today I start with taking a deeper look at Eclipse Kapua. It is a modular IoT cloud platform to manage and integrate devices and their data. My goal for the next weeks will be to demonstrate a multi-tenant capable installation of Eclipse Kapua on OpenShift, connecting several IoT devices and gateways to it. As a […]
