Host wordpress using docker/traefik under DOMAIN not subdomain

I am new to traefik and was wondering a few things.
I have 2 docker containers running and one uses traefik so i pointed the other to use that container to use the traefik. it crashes randomly.. rebooting the vm fixes this?

also how do i host a website like WordPress using docker and traefik? i dont want a subdomain but i want my MAIN domain address to load the WordPress. i have tried many different setups kind of cop/paste code to match. I have made a separate network for the WordPress but all i can find is traefik does subdomains only.. how would you host a website if this only makes and uses subdomains?

You'd have to post configuration files in order to get appropriate help. Traefik can definitely reverse proxy for the root domain.
