In the search box at the top of the Docker window, type 'mbentley', and then download the Omada Controller image as shown below:

(the default tag at time of writing was 5.9-chromium, by choosing beta-chromium you will get 5.13.30 or later)

NOTE: You can only use the -chromium images if you have Intel based Macs.  If you have a newer M1 or M2 based Mac, then 

please use the standard :latest tag as that will support the ARM64 architecture of the Mx chips.  Thanks @PappyChappy !

Run the container:

Give it a name and change the port mappings (host networking is only supported on Linux hosts, so we must port-map here):

and the logs will start to spin...you'll see the ports mapped as below

 It will chug for a while as it creates the Omada Controller environment on your Mac:

Some 5min later (or longer if your CPU is pokey) you'll see this in the logs:

and your Containers view will show stats properly:

You can now point your Mac's browser at https://localhost:8043 or https://127.0.0.1:8043 or https://your.macs.ip.address:8043  

(you will have to acknowledge unsafe and proceed)

You can now proceed to setup up your WAN and LAN settings.  

Enjoy!

Thanks for this correction (I've edite post#2 above).  For M1 or M2 based newer Macs, the ARM64 architecture is not supported by the -chromium builds (AMD64 (intel) only).  So pick the :latest or :beta build minus the chromium tag.
