Registration and Commissioning Workflow
This section describes the NuvlaBox registration and commissioning workflow.
Note that all HTTPS requests during this workflow are performed by the NuvlaBox, where all the information required by the NuvlaBox is returned to the NuvlaBox by Nuvla as responses to its requests. In other words, no incoming connection is required.
1. Installation of the Nuvlabox Engine software
Depending on your end goal, several options are available for the installation of the NuvlaBox Engine software. Both mechanism are similar in the sense that they follow the same registration + commissioning workflow. Only the trigger of the workflow is different.
1a. Manual installation: good for small scale infrastructures
Installation of the NuvlaBox Engine is performed by hand, from a dedicated bundle generated from Nuvla. See details here.
1b. Automated installation: good for industrialisation
A trigger installation script is embedded in the operating system of the edge device, in order to leverage a USB (or similar media) build from Nuvla. See details here
2. Activation of the NuvlaBox
Depending on the installation process selected, either a NuvlaBox record is created in Nuvla by the user (see step 1a above), or it is created automatically, via its API, using the automated method (see step 1b above).
Note that additional users or groups can be added to the NuvlaBox access control, such that they can access to the corresponding NuvlaBoxes.
2a. Manual activation
After registering a new NuvlaBox in Nuvla, the unique identifier of the newly created NuvlaBox (UUID) is embedded in the main compose file bundled and delivered to the user. This allows a single unauthenticated action to be performed, to activate the NuvlaBox. A unique identification token is created by Nuvla and returned to the NuvlaBox. From this point on, all communication between the NuvlaBox and Nuvla is authenticated and encrypted (TLS). The NuvlaBox then provides Nuvla with configuration information, such as the Docker REST API parameters.
2b. Automated activation
A trigger installation script is embedded in the operating system of the edge device, in order to leverage a USB (or similar media) build from Nuvla (see step 1b above).
An authenticated token is embedded in the USB key, allowing the script to create a new NuvlaBox resource in Nuvla. With the unique identifier returned to the NuvlaBox, the script performs the same steps as 2a above.
The state of the NuvlaBox at this stage is “activated”.
3. Commissioning of the NuvlaBox
Once the NuvlaBox is in Activated state, Nuvla will automatically generate all the information necessary to enable transparent management of the NuvlaBox device from Nuvla. For each NuvlaBox and respective owner, a VPN client configuration is created (based on the NuvlaBox owner’s organisation), which is then used to establish a secure communication route between the NuvlaBox and its owner and users.
Finally, resources are created to host the NuvlaBox status and telemetry, such that the NuvlaBox can report this information on a regular basis.
At this stage, the NuvlaBox state is set to “commissioned”. This means the NuvlaBox is fully operational, and telemetry is sent on a regular basis from the NuvlaBox to Nuvla.
