Hi,
Bruno, everything you have said is correct and it’s the preferred way to customize a Kura installation before the very first Kura boot.

Cristiano

Hi Scott,
it is not bound to Chef at all. Kura keeps all components' configurations in a file /opt/eclipse/kura/data/snapshots/snapshot_xxxxxxx. xml. Whenever you edit a configuration via web console, Kura saves a new snapshot file containing all components' configurations. You can modify these configuration files easily. My understanding is that when Kura starts up it reads the most recent snapshot file it can find in the folder /opt/eclipse/kura/data and applies the contents to the deployed components.
When you install Kura from scratch, you will find a basic snapshot_0.xml in the folder. Kura will encrypt this file on first startup, and all further snapshots will be encrypted before they are written to the filesytem. One way to retrieve a non-encrypted snapshot is to download it from the web ui.
I keep unencrypted custom snapshot files on my Chef server. I provide them to the folder mentioned before and restart Kura, so it reads the file and applies the config. I am not 100% sure how Kura deals with unencrypted snapshot files when there are encrypted files in the folder, so I usually delete all snapshot files from the folder before providing a custom snapshot_0.xml.
I think this is not the officially recommended way to configure Kura (as it's not documented), but it works fine. I need to manage a large number of Kura devices and definitely need a way to provide xml based templates as a basis for configuration. The MQTT approach doesn't fit there.
Kind regards
Bruno

Hi Bruno,
In answer to your question...no we don't mind restarting Kura. Actually our initial use case for this is deploying for the first time to 'clean' hardware. But in any event, is your method for accessing config info via snapshot files available? Is it bound to Chef in particular or can it be used in other ways?
Thanks,
Scott

Subject: Re: [kura-dev] changing config from outside kuraHello Scott,
do you mind restarting your Kura instance? We are using Chef to administrate our Kura devices and we access the configuration data via the snapshot files. A configuration change means updating the snapshot xml file on the kura device, and then restarting. Kura will load the new configuration.
Kind regards
Bruno

Hi,
We would like to be able to change the kura config admin information (i.e. some persistent data for some components) from outside of a running kura instance. For example, from a shell script. The idea is to automate some of the configuration of our components prior to deployment.
Is there an API for this...or some other procedure? I wasn't able to find with casual search, so forgiveness if it's there and I didn't find.
Thanksinadvance,
Scott
