Today I start with taking a deeper look at Eclipse Kapua<\/a>. It is a modular IoT cloud platform to manage and integrate devices and their data.<\/p>\n

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.<\/p>\n

As a first step, I will setup Kapua as a standalone application using pre-built docker containers.<\/p>\n

Then I will use a raspberry pi running\u00a0Eclipse Kura\u00a0to connect to Kapua and send test data.<\/p>\n

Next steps will be the port to OpenShift making use of persistent storage and scalability. And connecting sensors to the raspberry pi gateways to send\u00a0 some useful data.<\/p>\n

Setting up Kapua if you have a running docker service is fairly easy:<\/p>\n

You need to have a 64bit architecture, Docker version > 1.2, roughly 8 GB of free RAM and access to the internet to fetch the pre-built containers from docker hub.<\/p>\n

docker run -td --name kapua-sql -p 8181:8181 \\\r\n\u00a0\u00a0\u00a0 -p 3306:3306 kapua\/kapua-sql:0.3.2\r\ndocker run -td --name kapua-elasticsearch \\\r\n\u00a0\u00a0\u00a0 -p 9200:9200 -p 9300:9300 elasticsearch:5.4.0 \\\r\n\u00a0\u00a0\u00a0-Ecluster.name=kapua-datastore \\\r\n\u00a0\u00a0\u00a0-Ediscovery.type=single-node \\\r\n\u00a0\u00a0\u00a0-Etransport.host=_site_ \\\r\n\u00a0\u00a0\u00a0-Etransport.ping_schedule=-1 \\\r\n\u00a0\u00a0\u00a0-Etransport.tcp.connect_timeout=30s\r\ndocker run -td --name kapua-broker --link kapua-sql:db \\\r\n\u00a0\u00a0\u00a0 --link kapua-elasticsearch:es \\\r\n\u00a0\u00a0\u00a0--env commons.db.schema.update=true \\\r\n\u00a0\u00a0\u00a0-p 1883:1883 -p 61614:61614 kapua\/kapua-broker:0.3.2\r\ndocker run -td --name kapua-console --link kapua-sql:db \\\r\n\u00a0\u00a0\u00a0 --link kapua-broker:broker \\\r\n\u00a0\u00a0\u00a0--link kapua-elasticsearch:es \\\r\n\u00a0\u00a0\u00a0--env commons.db.schema.update=true \\\r\n\u00a0\u00a0\u00a0-p 8080:8080 kapua\/kapua-console:0.3.2\r\ndocker run -td --name kapua-api --link kapua-sql:db \\\r\n\u00a0\u00a0\u00a0 --link kapua-broker:broker \\\r\n\u00a0\u00a0\u00a0--link kapua-elasticsearch:es \\\r\n\u00a0\u00a0\u00a0--env commons.db.schema.update=true \\\r\n\u00a0\u00a0\u00a0-p 8081:8080 kapua\/kapua-api:0.3.2<\/pre>\n
Each line will then fetch the container and start them.<\/p>\n
In order to make the service accessible, I also add some firewall rules on my docker host:<\/p>\n
firewall-cmd --add-port 8080\/tcp\r\nfirewall-cmd --add-port 8081\/tcp\r\nfirewall-cmd --add-port 1883\/tcp<\/pre>\n
Thats all. Now you can acces the Kapua Web GUI on<\/p>\n
http:\/\/<ip_of_docker_host>:8080<\/p>\n
\"\"

The default credentials are:<\/p>\n
Username: kapua-sys\r\n\r\nPassword: kapua-password<\/pre>\n
Additionally there is a message broker running at<\/p>\n
tcp:\/\/<ip_of_docker_host>:1883<\/pre>\n
Username: kapua-broker\r\n\r\nPassword: kapua-password<\/pre>\n
And a RESTful API under<\/p>\n
http:\/\/<ip_of_docker_host>:8081\/doc<\/pre>\n
Username: kapua-sys\r\n\r\nPassword: kapua-password<\/pre>\n
That really was easy. Lets see what we can do with it.\u00a0Stay tuned for the next part: Installing Eclipse kura on a Raspberry Pi.<\/p>\n","protected":false},"excerpt":{"rendered":"
