Traefik not passing request path to Strapi CMS

Question

I'm trying to get Traefik and Stapi CMS to work together, but I'm having problems when trying to access the admin panel. For example, I will deploy both services and access the CMS via cms.example.com which loads the public/index.html according to strapi as expected.

The issue is when I try to access cms.example.com/admin the request again returns the public/index.html page and not the admin page. I have also inspected the strapi output on both requests it seems to be requesting the same route.

Can someone direct me on how to identify if the error is with Traefik not sending the path or if it's Strapi that's bombing out?

Here is some details about the deployments:

Traefik deployment:

docker run -d -v /var/run/docker.sock:/var/run/docker.sock -v $PWD/traefik.toml:/traefik.toml -p 80:80 -p 443:443 -p 8080:8080  --network web --name traefik traefik:2.0.2

Solved this by first manually building the Strapi Admin UI and then configuring Traefik to route requests.
