Hi everyone,
I managed to get things sort of sorted out:
1) I ran 'sudo apt-get remove docker*' on all nodes.
2) I then removed /etc/docker /var/lib/docker /etc/init.d/docker /run/docker on each node.
3) I ran 'sudo apt-get clean' on all nodes
4) rebooted all nodes
Starting from scratch I downloaded the get-docker.sh and copied it to each node and ran the following:
sudo sh get-docker.sh
sudo usermod -aG docker pi
sudo systemctl start docker.service
sudo systemctl enable docker.service
docker info
docker run hello-world
The next step was to run 'docker init swarm' on one of the nodes to create the manager node. This looks to have completed properly as I got 'swarm initialized....'
At this point, the responsiveness of the node fell through the floor.. top shows CPU 98% idle but keystrokes etc are delayed by 30-40 seconds. I am thinking maybe memory?? but am not sure what the next step would be after this...
As an FYI.. the whole issue of the master node hanging went away when I switched from Raspberry Pi OS to Ubuntu 20 server.. I even managed to get kubernetes installed..
What made this interesting was that the master is a Pi 3b with an ARM7 V4 while the rest are Pi 2B+ with ARM7 v5..
I may have spoken to soon. It finished running sudo sh get-docker.sh, which it hadn't before, but it still fails to start Docker Application Container Engine.
I switched over to Ubuntu and not only did Docker install, I got Kubernetes installed and working as well.. I had to try a couple of minor things, but mostly missing packages

Thanks for the outline of step by step commands. This worked for me also on RPI3

Thank you, @william bell! That did the trick!
