The following instructions explain how to build a Kaa endpoint SDK and i= ntegrate it with snappy Ubuntu Core. Required software co= mponentsEnsure the following components are installed on your machine. VirtualBox Vagrant Latest Kaa sandbox TopologyTo integrate Kaa with snappy Ubuntu Core, you need to use two virtual bo= xes: one to deploy snappy Ubuntu and a Kaa client and the other to deploy t= he Kaa sandbox. Configuri= ng and building sample Kaa clientWe assume that the Kaa sandbox = is already started. NOTE: Make sure that the Kaa client is ab= le to connect to Bootstrap and Operations servers deployed on the Kaa sandb= ox. To configure and build a sample Kaa client, proceed as follows: Go to http://localhost:8080/sandbox/. Enter the IP address of your Kaa sanbox VM into the text field and then= click Change (in the following screenshot, the IP address= is 192.168.100.100).= i> Wait till the service restarts.Get the latest Kaa code from github. =20 $ git clone gi= [email protected]:kaaproject/kaa.git $ cd kaa/examples/ =20Configure and generate C SDK for your Kaa client.NOTE: You can f= ind sample Avro schemas in c-sdk-sample/avro/path. Avro schemas =20 $ ls c-sdk-sam= ple/avro/ configuration.avsc log.avsc profile.avsc=20 Create a snappy application in web UI. NOTE: Refer to managing applic= ations in case of difficulties. Add a new configuration schema for your application (look= at c= onfiguration.avsc).NOTE: Refer to the configuration s= chema section in Admin UI guide in case of difficulties. Add a new profile schema for your application (look at profile.avsc).NOTE:= span> Refer to the profile schema section in Admin UI = guide in case of difficulties. Add a new log schema for your application (look at log.avsc).NOTE:= Refer to the log schema section in Admin UI guide in case of dif= ficulties. Generate the C SDK for your application.NOTE: Refer t= o the generating SDK section in Admin UI guide in case of di= fficulties.Build a Kaa client with the generated C SDK. Remove ev= erything in the c-sdk-sample/libs/kaa folder and unzip the generated SDK to= that folder.

Building snappy package= h2>To build a snap package, proceed as follows: Install snappy Ubuntu tools by executing the following commands eith= er from Ubuntu or from the Kaa sandbox (in case you are using another OS). = Building inside Kaa sandbox is preferable, because system upgrade step may = harm your system. Install Snappy tools =20 $ sudo add-apt= -repository ppa:snappy-dev/beta $ sudo apt-get update $ sudo apt-get upgrade #do it for your own risk, you better to use virtual= machine $ sudo apt-get install snappy-tools=20Create the correct folder structure. Refer to the official snappy Ub= untu Core documentation for details. =20 $ mkdir snappy= -kaa $ mkdir snappy-kaa/meta $ mkdir snappy-kaa/bin =20Copy the previously built Kaa client to the snappy-kaa/bin directory= . =20 $ cp kaa/examp= les/c-sdk-sample/build/sample_c_client snappy-kaa/bin/client # Copy with re= name sample client to bin directory=20Create the package.yaml file in the snappy-kaa/meta directory with t= he following context. package.yaml =20 name: kaa vendor: Vendor Name icon: meta/kaa.png version: 0.0.1 binaries: - name: bin/client description: "snappy example: kaa c client"=20Create the readme.md file in the snappy-kaa/meta directory with the = following context. readme.md =20 Minimal C Kaa = client for snappy Any other info about your application. =20Build a snap package from the snappy-kaa directory. Build snappy package =20 $ snappy build= snappy-kaa =20As a result, you should get the kaa_0.0.1_all.snap file. =20 $ ls snappy-ka= a bin kaa_0.0.1_all.snap meta=20Known issue: your readme.md should contain at least two lines of t= ext or package build will silently fail. this is some kind of undocumented = behavior. Installing snappy Ubuntu=To locally deploy snappy Ubuntu, run the following commands. Deploy Snappy ubuntu =20 $ vagrant init= ubuntu/ubuntu-core-devel-amd64 $ vagrant up $ vagrant ssh =20As a result, you should be connected to your snappy Ubuntu box. =20 Welcome to Ub= untu Vivid Vervet (development branch) (GNU/Linux 3.18.0-9-generic x86_64) * Documentation: https://help.ubuntu.com/ Welcome to the Ubuntu Core rolling development release. * See https://ubuntu.com/snappy It's a brave new world here in snappy Ubuntu Core!
