Say, I have 20 scripts in a path 'Path1'(Basically the Test Lab path).
Finally, click on the upgrade now button to upgrade OnePlus 5 to its. Notice that the download link for the installer is present in the “metadata” object. I need to develop a OTA, which will provide me All Runs of the Test Script present in the path that I give. Click on the local upgrade option The phone will fetch the ROM package automatically. This is the release metadata for version 1.0.0. Now that we have two versions of the application (along with an installer) and the Cincinnati server running locally, we can create the release metadata and push it to the docker repository that we created in part 1.Ĭreate a JSON file called “1.0.0.json” with the following contents. You can find the source code and the installers below: I have created two versions of a sample application. The download location for the installer is fetched from the metadata.

The client application (shown in orange) uses this graph to determine if an upgrade is available. Cincinnati pulls the metadata stored in a docker registry, builds, and returns a DAG (directed acyclic graph) repesenting the upgrade paths along with metadata. The client application checks for updates by reaching out to a central update server (Cincinnati Server shown in green above). It describes a method for representing transitions between releases and allowing a client to perform automatic updates between these releases.ĭiagrammatically the solution is Architecture Diagram Cincinnati is an update protocol designed by Openshift as a successor to Google’s Omaha update protocol.
The Cincinnati protocol will serve OTA updates to the client. NET core console application that can upgrade itself using the Cincinnati update protocol.
