This is an example IoT demo showing a realtime updating dashboard of data streaming from an IoT gateway device (based on Eclipse Kura) through an Eclipse Kapua-based instance.
It demonstrates realtime fleet telematics, package tracking, alerting, and a telemetry dashboard showing critical measurements of packages in transit, including temperature, humidity, displacement, light levels, etc.
Technologies used:
- Eclipse Kapua
- AngularJS
- Patternfly
- JBoss Middleware (EAP, JDG, and more to come)
The demo deploys as an Angular.js app running on a Node.js runtime, along with JBoss Data Grid and a Data Grid proxy component that properly handles browser-based REST requests and relays to JBoss Data Grid via the Hotrod protocol.
Eclipse Kapua is also deployed and acts as the IoT cloud management layer.
Follow these steps to build and run the demo:
-
Install and have access to an OpenShift Container Platform 3.4 or later or OpenShift Origin 1.4 or later. You must be able to use the
occommand line tool. -
Clone this repo
git clone https://github.com/redhat-iot/summit2017
cd summit2017
- Issue the following commands to create a new OpenShift project and deploy the demo components:
oc new-project redhat-iot --display-name="Red Hat IoT Demo"
oc policy add-role-to-user view system:serviceaccount:$(oc project -q):default -n $(oc project -q)
./openshift-deploy.sh
You can monitor the build with oc status or watch the deployments using the OpenShift web console.
If you see some components with "No Deployments" or are not building, you may need to add imagestream
definitions for wildfly and jboss-datagrid. To do so, run these commands:
oc login -u system:admin (Or login with any userid that has cluster-admin privileges, TODO: Explain all options here)
oc create -n openshift -f https://raw.githubusercontent.com/jboss-openshift/application-templates/master/jboss-image-streams.json
oc create -n openshift -f https://raw.githubusercontent.com/openshift/origin/master/examples/image-streams/image-streams-centos7.json
Once everything is up and running, you can access the demo using the URL of the dashboard route,
for example http://dashboard-redhat-iot.domain
Confirm that all the components are running successfully:
oc get pods --show-all=false
You should see the following pods and their status:
| NAME | READY | STATUS |
|---|---|---|
| dashboard-1-xxx | 1/1 | Running |
| datastore-1-xxx | 1/1 | Running |
| datastore-proxy-1-xxx | 1/1 | Running |
| elasticsearch-1-xxx | 1/1 | Running |
| kapua-api-1-wc1l7 | 1/1 | Running |
| kapua-broker-1-xxx | 1/1 | Running |
| kapua-console-1-xxx | 1/1 | Running |
| simulator-1-xxx | 1/1 | Running |
| sql-1-xxx | 1/1 | Running |
Eclipse Kapua exposes a REST API which can be used to access Kapua data and invoke Kapua operations. The REST API application is running as a dedicated Java process.
For example, to use the curl command login to Eclipse Kapua and retrieve an authentication token:
curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{"password": ["your_password"], "username": "your_username"}' 'http://api-redhat-iot.domain/v1/authentication/user'
Once logged in, the retrieved token can be passed for future API calls, e.g.
curl -X GET --header 'Content-Type: application/json' --header 'Accept: application/json' --header 'Authorization: Bearer <AUTH_TOKEN_HERE>' http://api-redhat-iot.domain/v1/my_scope/devices
The complete API documentation can accessed using the URL of the api route, for example http://api-redhat-iot.domain/doc. More information on the REST API can be found in the Eclipse Kapua user guide.
The following command will add the template and the options to the "Add to project" screen in the "Other" section. The template will deploy with defaults the same as it does using the scripts above.
oc create -f iot-demo.yml
The template contains various optional parameters that can be specified when deploying the components:
oc process -f openshift-template.yaml OPTION1=value OPTION2=value | oc create -f -
MAVEN_MIRROR_URL- To speed up Maven-based buildsGOOGLE_MAPS_API_KEY- for your personal Google Maps API keyGIT_URIandGIT_REF- overrides where source code is pulled (e.g. using your own personal fork)IMAGE_VERSION- Docker image tag to use when pulling Kapua (defaultlatest)DOCKER_ACCOUNT- Name of docker account to use when pulling Kapua (default:redhatiot)
There are other options in the template that can be overridden if you know what you are doing!
oc delete all --all -n redhat-iot && oc delete configmap hawkular-openshift-agent-kapua data-simulator-config -n redhat-iot
This will delete everything but the project "Red Hat IoT". This is suitable for testing new scripts, template, etc.
