Hi,
 
I managed to have docker running on a S812 box (Minix X8-H Plus model same as you), you need to recompile the kernel with all the required flags set for docker to work.
I started from Balbes150's latests images with 4.x kernel (but should be good as well using 5.0), downloaded the kernel sources from Kevin Hilman's repo (https://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git), made the .config changes required for docker to work (you can have a look at docker's site, or to the script that validates current kernel flags for docker), build the kernel uImage, headers and modules, installed everything and rebooted. After that the docker service runs fine (even in swarm mode).
 
The only thing I didn't managed to get working was wifi, but since I'm plugged in ethernet i didn't investigate that much to get the ap6335 to work. I'm using the default mxiii dtb from balbes' release, it works fine.

This has been discussed many times on the forum, look for information.

find your box recovery button. use toothpick mode to activate. using update method does not always work. 
 
watch this: 
 
 
 
 

Much simpler would be...Every Armbian image for the s802/s812 comes with it in the boot partition. When you burn the *.img to the SD card, turn on your box with the recovery button pressed in using the toothpick method. you do have a recovery button? the boot logo flashes once then let go of the button and should flash once more on its own. you will hear a faint piezo tone from the box when it flashes..but those are details. just watch for the logo flashing off and back on. and you're set.

did you try  the NEXT version?

Updated images Armbian 20170531. Changes to scripts activate the multi-boot and run system from external media. In the new version of the scripts allow to start the system from any USB socket (if the is connected other USB media). Back support "nodm", now in the images is used in common with the main branch Armbian authorization system. If you want you can install the package "lightdm" in version Mate-that-be to have a graphical authentication when you log into the system (just don't forget together with the installation of lightdm, remove the nodm package, otherwise they will interfere with each other). Other changes see the description of changes to main branch Armbian (replacement browser on Chromium, etc.).
New scripts activate the multi-boot and system start-up can be found here. You can download them and use for old images. To reactivate the multi-boot again.
