 Bring all components down, remove the `traffic_ops/ca` directory, and delete

+Re/installed docker from the command line to use user=[your username] flag, 
and update the dockerfiles in the code for both enroller and traffic_ops in the 
cdn-in-a-box folder with the correct architecture for the M1. Link to install 
info for docker: https://docs.docker.com/desktop/install/mac-install/  and use 
Install from command line.

+- Then update cdn-in-a-box/traffic_ops Dockerfile line 46 to 
-aarch64/pgdg-redhat-repo-latest.noarch.rpm after EL-${RHEL_VERSION%%.*} 
+- Add on line 18 of the cdn-in-a-box/enroller Dockerfile 
--platform=linux/amd64 after the 1st FROM.

+Build and run of it:
+In the trafficcontrol/infrastructure/cdn-in-a-box directory run the following:
+ 
+- make build-builders ~~> this will create all the rpms and copy each rpms 
into its own folder in the cdn-in-a-box project. This will also create the dist 
folder under trafficcontrol folder structure even if you deleted yours.
+
+- docker-compose up ~~> this will create docker images, and if rebuild is 
needed, run docker-compose up --build.

+
+"Privileged configurations are applied during the installation with the --user 
flag on the install command. In this case, the user is not prompted to grant 
root privileges on the first run of Docker Desktop. Specifically, the --user 
flag:
+
+- Uninstalls the previous com.docker.vmnetd if present
+- Sets up symlinks for the user
+- Ensures that localhost is resolved to 127.0.0.1
+
+The limitation of this approach is that Docker Desktop can only be run by one 
user account per machine, namely the one specified in the -–user flag."
+
+The above is a direct quote found in Installing from the commandline: 
https://docs.docker.com/desktop/mac/permission-requirements/
+
+Note: The homebrew install did not work, neither did the Docker.dmg none 
command line install.

Review Comment:
   I'm sorry, I meant that the command-line install is the only one that did 
work. I will fix it to make it clear. (: Also, because this was the reason my 
docker containers were not loading in localhost host and this also fixed it.
