Thanks a ton @francislavoie!!! You made my weeks of efforts come to life.
Following the documentation and other examples online, was able to setup my Godaddy subdomains as reverse proxy on Caddy, and now everything works flawlessly!!
One last thing, i did try to remove the ports: as you mentioned from the compose files and redeployed the containers.
Tried updating Caddyfile to below, and it doesn’t seem to route the requests to the containers. Is this correct?
sub1.mygodaddydomain.com {
reverse_proxy portainer-ce
}
