I am currently trying out Mender and have followed the steps provided to setup a pi with the correct img, then enabled SSH and installed the Mender Client. This has appeared in the Mender hub and has been accepted, allowing me to push updates to it which is great.
Now I’m trying to find out what the best way to do this over numerous devices (potentially 100+) would be? My idea was to use this as a golden img and copy it to another SD card and use it in another pi, so it would already have the correct img, config and client setup. When trying this, the new pi boots fine and connects to the network, but it does not appear in the Mender hub to accept it. I thought maybe that it has copied over ok but the client potentially hasn’t started, hence it not showing in the hub. Any advise on why that may be happening would be appreciated.
If this way is not feasible, I wondered what the best / most efficient way to get the Mender client onto many devices would be?
Thanks in advance!
