How can I map a hostname (subdomain) to Docker Container with Traefik? - docker

Question

I have multiple Docker containers running nginx that serves up a web application. These containers are running on a virtual machine abc.com. They all require https.
If I have just one container running, I can access the container running at abc.com:443 no problem. I can also run multiple containers using docker run and port mapping where I can map a port to 433 like this:
VersionA 0.0.0.0:5000->443 can hit on abc.com:5000
VersionB 0.0.0.0:5001->443 can hit on abc.com:5001
VersionC 0.0.0.0:5002->443 can hit on abc.com:5002
What I would like is:
vA.abc.com -> VersionAContainer:443
vB.abc.com -> VersionBContainer:443
vC.abc.com -> VersionCContainer:443
These containers will spin up and close regularly and need them to be picked up by Traefik. What is the proper build command for traefik and run command for the container using labels?
This is how I was running the Traefik container with no luck.
sudo docker container run -d --name traefik_proxy \
--network traefik_webgateway \
-p 80:80 \
-p 443:443 \
-p 8080:8080 \
--restart always \
--volume /var/run/docker.sock:/var/run/docker.sock \
--volume /dev/null:/traefik.toml \
traefik --docker --logLevel=INFO --api \
--entrypoints="Name:http Address::80 Redirect.EntryPoint:https" \
--entrypoints="Name:https Address::443 TLS" \
--defaultentrypoints="http,https"
And this is how I was running my container:
sudo docker run -d --name some-nginx \
--network traefik_webgateway \
--label traefik.docker.network=traefik_webgateway \
--label traefik.protocol=https \
--label traefik.frontend.entryPoints=http,https \
--label traefik.frontend.rule=Host:something.localhost \ # unsure if this is correct to use local host or abc.com
--label traefik.port=443 \
--label traefik.frontend.auth.forward.tls.insecureSkipVerify=true \
container:latest
