We have just released the test version of the Mender management server! While we have had the client-side component out for some time, we have now released a version of the management server. You can now use it to deploy software updates (images) to the client, either a virtual one or a physical device. We encourage you to try it and would very much appreciate any and all feedback:
Now with the management server component you can deploy an image-based update through our UI. And both client and server-side are open source (Apache 2.0). You can read more about how it works here.
Please contact us with any feedback or questions!
