While mine looks like:

 $ docker exec fleet-tracker ps -ef
 PID   USER     TIME  COMMAND
     1 roundup   0:00 /usr/bin/dumb-init ./roundup_start fleet=tracker
     7 roundup   0:20 {roundup-server} /usr/local/bin/python /usr/local/bin/roundup-server -n 0.0.0.0 fleet=tracker

 $ docker exec fleet-tracker sh -c 'wget -q -O /dev/null --no-verbose http://localhost:8080/fleet/; echo $?'

I have no idea why/how you are getting a 503. In fact I can't find
Roundup ever using/returning 503 or http.SERVICE_UNAVAILABLE anywhere
in the Roundup code. So I claim the 503 is not coming from Roundup.

I verified that the error from wget when connecting to the wrong port
is different:

   wget: can't connect to remote host (127.0.0.1): Connection refused

If it can't resolve the hostname, wget returns:

   wget: bad address 'loclhost:8080'

Is there some other web server running on the system or inside the
docker container that wget inside the container could be hitting?

Can you try running docker with a -p of:

   -p 127.0.0.1:<external port>:8080

where external port is the first port number you are currently using.
The docs recommends using 127.0.0.1 so that docker doesn't play games
with the external firewall rules on your host.

I tried running docker using just '-p <external port>:8080' and I
can't reproduce your error. The heartbeat check works fine.

So I am stumped as to why this is is erroring.
