Create custom image with Mender and Portainer [ConnectCore 6UL SBC]

I have a couple of questions to help med decide if the ConnectCore 6UL SBC Express could be what I am looking for.

From what I’ve seen, offers seamless updates of the OS, and Portainer can be used to manage the Docker containers.
Does anyone already now know that this will not work for some reason, or advice against it? The idea is to make a custom Digi Embedded Image that have these two services added.

should work because it has native Yocto support:
