using azure ad for user authentication. azure ad is free but i have a paid o365 so i use that to authenticate against for access to my containers that have a fqdn attached/directed to it. and most of the containers/apps have sso with azure ad integration option available so no more logging into each single app/container.
CloudFlare ZT tunnels coupled with an Azure AD. Work’s amazingly with their containers to keep the tunnel alive.
Traefik has a GUI you can installed. I use Cloudflare ZT
