I've been following the Ziti wizard step-by-step to run OpenZiti locally with Docker. So far, the experience has been great because I don't know what I'm doing and it's working. Seriously! Right now, I am currently stuck at 'Testing the Network' because I don't know how to add the ziti component entries to my operating system hosts file or DNS nameserver. It's probably out of scope, but I thought I would ask for help. Thanks so much!
It's out of scope, yeah. You kinda need to know how/what the hosts file is. You can read a bit about it here How To Find and Edit Your Mac Hosts File (in 4 Steps) (if you're on MacOS)
Bascially, you'll need to add the entries to that file (or control your DNS some other way) so that the hostsnames are known.
Add entries to that file, but understand that it's easy to forget that you've done this. So do this with caution. You've been warned 
On my macmini I edited the file with vi in privileged mode (use whatever editor you like):
sudo vi /private/etc/hosts
Then made it look like this:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
#127.0.0.1 m1mini
127.0.0.1 ziti-edge-controller ziti-edge-router-1 ziti-edge-router2
