Overview
Eclipse Dirigible is an open-source cloud development platform that provides capabilities for end-to-end development processes from database modeling and management, through RESTful services using server-side JavaScript, to pattern-based user interface generation, role-based security, external services integration, testing, debugging, operations and monitoring.
Some of the unique features include:
- In-System development
- Low-Code/No-Code development
- Modeling and Generation from templates
- In-App extensibility
- Enterprise JavaScript APIs
- Web IDE
The platform aims to unify open-source business services by providing software developers with a convenient set of tools for building, running, and operating business applications in the Cloud. Dirigible is also part of the Eclipse Cloud Development top-level project.
Setup
Starting with the Eclipse Dirigible 5.0 release (and more specifically with the 5.3 version), there is a built-in integration with the SAP Cloud Platform Kyma environment. To deploy Eclipse Dirigible in your Kyma cluster, follow these steps:
- Enable the Kyma environment in your global account.
- Kyma is now available in the Trial landscape. See Kyma runtime available in trial – and now we are complete.
(Kyma Environment)
- Once enabled, log in to the Kyma dashboard.
- Copy and save (e.g. dirigible-kyma.yaml) on your desktop the following YAML definition:
- Deployment - creates a Kubernetes Deployment controller
- Service - creates a Kubernetes Service network
- dirigiblelabs/dirigible-sap-kyma - the Kyma tailored Dirigible docker image
- DIRIGIBLE_THEME_DEFAULT - an environment variable for the Dirigible theming (e.g. "fiori")

(Dirigible Deployment Descriptor - e.g. dirigible-kyma.yaml)
- Go to the default namespace:
(Kyma Dashboard)
- Click the Deploy new resource button:
(Kyma Deploy New Resource)
- Provide the saved YAML definition (e.g. dirigible-kyma.yaml).
- Once deployed, the Workloads chart will update to 1/1 Deployments and 1/1 Pods.
(Kyma Workloads)
- Go to Discovery and Network -> API Rules.
- Click on the Create API Rule button.
- Provide a value for the API Rule Name (e.g. dirigible).
- Provide a value for the API Rule Hostname (e.g. dirigible).
- Select dirigible (port: 8080) service from the API Rule Service dropdown.
- Leave the default access strategy.
- Click the Create button.
(Kyma Create API Rule)
- Copy the newly created API Rule Host and save it for later:
(Kyma API Rules)
- Go to the Service Management -> Catalog section.
- Search for the Authorization & Trust Management service.
(Kyma Service Catalog)
- Create a new service instance:
- Provide a value for the service instance Name (e.g. xsuaa-dirigible).
- Set the service instance Plan to application.
- Provide additional parameters as a JSON:
{
"xsappname": "dirigible-xsuaa",
"oauth2-configuration": {
"token-validity": 7200,
"redirect-uris": [
"https://<api-rule-hostname>.<cluster-id>.<kyma-region>.k8s-hana.ondemand.com"
]
},
"scopes": [
{
"name": "$XSAPPNAME.Developer",
"description": "Developer scope"
},
{
"name": "$XSAPPNAME.Operator",
"description": "Operator scope"
}
],
"role-templates": [
{
"name": "Developer",
"description": "Developer related roles",
"scope-references": [
"$XSAPPNAME.Developer"
]
},
{
"name": "Operator",
"description": "Operator related roles",
"scope-references": [
"$XSAPPNAME.Operator"
]
}
],
"role-collections": [
{
"name": "dirigible",
"description": "Dirigible Developer",
"role-template-references": [
"$XSAPPNAME.Developer",
"$XSAPPNAME.Operator"
]
}
]
}
(Authorization & Trust Management Service Instance Additional Parameters)
- For more information about the XSUAA configurations go here.
- NOTE: It's important to replace the redirect-uris value with the previously created API Rule Host (e.g. https://dirigible.c-71b4221.kyma.shoot.live.k8s-hana.ondemand.com)
(Authorization & Trust Management Service Instance Additional Parameters)
- Once the service instance is in Running status, it's time to bind it to the Dirigible application.
- Click on the Bind Application button and select the Dirigible deployment (e.g. dirigible) form the dropdown:
(Authorization & Trust Management Service Application Binding)
- We are almost ready to run Dirigible on Kyma. The last step is to provide one additional environment variable to the Dirigible Deployment:
- Navigate to the Workloads -> Deployments section.
- Edit the Dirigible deployment (e.g. dirigible).
- Find the DIRIGIBLE_THEME_DEFAULT environment variable and add a new one:
{
"name": "DIRIGIBLE_HOST",
"value": "https://<api-rule-hostname>.<cluster-id>.<kyma-region>.k8s-hana.ondemand.com"
}
- NOTE: It's important to replace the DIRIGIBLE_HOST value with the previously created API Rule Host (e.g. https://dirigible.c-71b4221.kyma.shoot.live.k8s-hana.ondemand.com)
(Dirigible Deployment Environment Variables)
- Last but not least, we need to assign the required roles:
- Go back to the SAP Cloud Platform cockpit and go to Security -> Trust Configuration.
- Then, select the sap.default trust configuration:
- Search for your username (your email) and assign the dirigible role collection:
- To access the Eclipse Dirigible instance, go to Configuration -> API Rules, and open the Dirigible URL (e.g.
https://dirigible.<cluster-id>.<kyma-region>.k8s-hana.ondemand.com). - Once started, you can begin developing your next business application with Eclipse Dirigible:
