From the maori word for tank/container, Eclipse Kura™ is a versatile software framework designed to supercharge your edge devices. With an intuitive web interface, Eclipse Kura™ streamlines the process of configuring your gateway, connecting sensors, and IoT devices to seamlessly collect, process, and send data to the cloud. Eclipse Kura™ provides an extensible Java API for developing custom plugins within the framework. Additionally, it offers a REST API, enabling the use of Eclipse Kura™ as a backend service in your application.

Eclipse Kura™ runs on an edge gateway, which can be anything from a small SBC(single-board computer) like a Raspberry Pi, or a powerful high-performance computer.

• Kura™ Services: Provision and set up features to run on your gateway, such as an MQTT broker.
• Kura™ Networking: Manage Network connectivity, including
• Kura™ Wires: Design data flows and data processing streams effortlessly with a drag-and-drop visual editor.
• Kura™ Cloud Connectors: Extendable cloud connector system.
• Kura™ Drivers: Extendable service that handles reading data off of external devices.
• Kura™ Snapshots: Securely store and re-apply gateway settings for convenience.
• Kura™ Security: Easily and safely store your secrets.
• Kura™ Container Orchestrator: Manage Docker or Podman containers on your gateway for ultimate flexibility.
• Kura™ AI Inference: Run Nvidia Triton Models on the edge.
• Kura™ Plugins: Add and Extend the framework by adding your own Services, and Drivers.
• Kura™ REST Service: Embed the framework as a backend in your own edge applications.

Eclipse Kura™ is compatible with Java 8 and Java 17.

Eclipse Kura™ provides pre-built installers for common development boards. Check the following link to download the desired installers. Take a look at our documentation for further information on supported platforms and installer types.

Eclipse Kura™ is also available as a Docker container.

In order to be able to build Eclipse Kura™ on your development machine, you need to have the following programs installed in your system:

• JDK 1.8
• Maven 3.5.x

sudo tar -xzf <archive-name>.tar.gz

# Adoptium JDK 8
export JAVA_8_HOME=/Library/Java/JavaVirtualMachines/<archive-name>/Contents/Home
alias java8='export JAVA_HOME=$JAVA_8_HOME'
java8 

brew install [email protected]

export PATH="/usr/local/opt/[email protected]/bin:$PATH"

sudo apt install openjdk-8-jdk

Change to the new directory and clone the Eclipse Kura™ repo:

git clone -b develop https://github.com/eclipse/kura.git

Move inside the newly created directory and build the target platform:

mvn -f target-platform/pom.xml clean install

Build the core components:

mvn -f kura/pom.xml clean install

Build the examples (optional):

mvn -f kura/examples/pom.xml clean install

Build the target profiles:

mvn -f kura/distrib/pom.xml clean install -DbuildAll

Alternatively, you can use the build scripts available in the root directory.

./build-all.sh

or

./build-menu.sh

and select the profiles you want to build.

The Eclipse Kura™ container build process currently only supports x86 containers. Following the instructions below will build two containers. One based on Alpine Linux kura-alpine-x86_64, and another on Ubi8 kura-ubi8-x86_64.

Build Eclipse Kura™ as per our instructions. To build the containers you'll need to change the target of the "Build the target profiles" step like the following:

mvn -f kura/distrib/pom.xml clean install -DbuildAllContainers

After this command completes, images can be found in your preferred container engine image list.

We currently support two setups for Eclipse Kura™ development:

• Eclipse Kura™ Development Environment Setup: This is the full setup allowing you to contribute to the core Eclipse Kura™ project codebase. It will install all the IDE plugins and formatters to have a pleasant development experience and clone the Eclipse Kura™ source code on your workstation.
• Add-on Development Environment Setup: This setup will allow you to develop applications or bundles running on Eclipse Kura™. It will install only the APIs and the examples and is best suited for developing Eclipse Kura™ add-ons.

Contributing to Eclipse Kura™ is fun and easy! To start contributing you can follow our guide here.
