Made changes so it doesn't automatically bind any TCP listener to prevent nanomq.conf TCP listener from being overwritten.
It is having problems whenever I provide my nanomq.conf file that has a TCP listener with a different port, It only binds to default 1883 and not my conf file.

Output from 'top' in the docker container:

my nanomq.conf file:

mqtt {
    retry_interval = 10s
    keepalive_multiplier = 1.25
}

listeners.tcp {
    bind = "0.0.0.0:444"
}

Docker command used to run the container:

docker run  -p 444:444 -p 1883:1883 -d  -v /root/nanomqDockerCompose/nanomq.conf:/etc/nanomq.conf -v /root/nanomqDockerCompose/nanomq_pwd.conf:/etc/nanomq_pwd.conf --name nanomq emqx/nanomq

It only binds to 1883 as provided in

But in other variants of the image (slim,dev,full) it is different for some reason:
