Questions about application deployment on kura [message #1800715]

Hello.

I have a couple of questions about app deployment on kura devices.

1) From what i understand the deployment package model is made for deploying one somewhat small application via a deployment package and not for deploying multiple applications that share a lot of bundles?

2) If my assumptions in the first question are correct, how would one go about deploying multiple applications that share a lot of bundles? Doing this via deployment packages would mean a lot of duplication of bundles between the deployment packages and if the applications are big enough, updating would mean updating the whole deployment package instead of updating only one bundle.

3) Is it possible to deploy bundles remotely to a kura device the same way, or similarly to what one does with kapua, via it's rest services?

4) Are there better alternatives for kura remote deployment and administration than kapua?

Hi,
a deployment package is a sort of zip file that wraps one or more bundles.
At this time we don't have REST APIs in ESF that support bundle deployment, but you can use the Kura Deploy-V2 cloudlet to deploy your bundles in the very same way as Kapua does. http://eclipse.github.io/kura/ref/mqtt-namespace.html

Kura and Kapua are tightly integrated and developed, more or less, in parallel. But you can implement the same APIs in your own solution if you keep the same contract.

Best regards,
Matteo

Thanks for the answer.

I tried reading your provided link for the DEPLOY-V2, but it seems to only mention operations with deployment packages (nothing about raw bundle deployment). Am i missing something?

Yes, the main scope for deploy V2 is to manage deployment packages.
It can also manage shell scripts.

Best regards,
Matteo

Another quick question:

Is it possible to trigger the DP package installation event in a similar way to how apache file install plugin works, where i just throw a bunch of bundles inside a load folder and it automatically picks them up? Or is it only possible via rest/ui?

There exists a packages folder and a file that keeps the mapping and should be named dpa.properties.

In the marketplace there is also a dp that provides apache file install.
