SOVLED.
Quickly tried above strategy and learned nothing.
I have given up on the mysql root password with a $ sign,
If I discover an extra hour or two, I my revisit this.
Since the install document insists that it is a 1-2 hour install,
I thought that I ought to hone my skills at redoing this install!
So, deleted all including Git repository.
Ran steps 1-8, but step 8 died with MySQL errors.
This was weird:
(1) I recorded that it ran to a successful end previously.
(2) now seems obvious that the documentation is totally missing
the creation of mysql objects.
I created the mysql objects, reran step 8 and got weirder errors.
So I saved my configuration files setup from steps 1-7, namely
.env
docker-compose.local.yml
local.env
config\apache\settings_php\settings.local.php
config\proxy\traefik.local.toml
scripts\proxy\ssl-certs\local-windows-only.sh
Deleted all including Git repository.
Dropped and recreated my MySQL objects.
Ran steps 1-5 copying my saved configuration files
Ran steps 6-8, step 8 says
Done.
'all' cache was cleared.
that last cycle took 1.5 hours
Step 9: Tada!
Tomorrow night I will do steps 10 and 11 and start figuring out Islandora.
Thanks all
