Getting Started with Pi 3 with Hosted Mender (OTA updater)

A nice post about getting started with Raspberry Pi 3, OSX, and Hosted Mender (over-the-air software updater):

Thanks!

EDIT. On second thought... The USP of Mender is that it's open-source and you can install it on-premise. I regret to say that currently the server install borders on unusable.
There is a "demo" install, it can work (I've seen it, it's nice) but it consumes huge resources, like 2 CPU cores and over 2GB or RAM, and it's more or less designed for a desktop machine. The qemu virtual device that comes with the demo (to receive OS updates) is a hog, but the server isn't lightweight either. (It's a bunch of Docker containers)
Then there is a "production" install, it should work in a headless server configuration but there I was simply unable to get it to work.

Besides that, the real problem seems to me the absence of "official" support, compounded by the absence of user community.
If the code has indeed any merit I wouldn't be surprised to see a fork.

So for now and for my part I'm getting stopped with Mender I think :)

Thanks for the feedback on Mender, I work on the project.

The demo server is indeed not optimized for performance. But with Mender 1.7 the virtual device is using native x86 emulation, so it is much faster (update deployment time went from 3 -> 1 minute). If you want to invest time in the production install, it is indeed more complex (due to scale and security constraints) and this is why we offer Hosted Mender so you can focus on something else than server configuration.

Mender does have a very active community, take a look at the mailing list activity: https://groups.google.com/a/lists.mende ... rum/mender

Finally I wanted to let you know that Mender now supports Raspbian: https://hub.mender.io/t/raspberry-pi-3- ... b-raspbian

Hope this helps!

That looks like good progress. Congratulations!
