Docker run command is not correct in README file

I followed the steps of the README file, however found that Docker Run command was not correct

The suggestion is to use docker run --rm -p 443:443 pintura however the nginx service running in the container is not listening on port 443, it is listening on port 80 only.

I had to install the following packages to find this out

apt-get install procps net-tools

ps -a

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

nginx        7  0.0  0.1  32904  2504 ?        S    15:22   0:00 nginx: worker p

root       266  0.0  0.1  36632  2748 pts/0    R+   15:34   0:00 ps -aux

And then

netstat -pln

Active UNIX domain sockets (only servers)

When using the following command (for testing)

docker run -d --rm -p 3443:443 -p 3080:80 --name reservepintura pintura

I was able to view Pintura service at http://localhost:3080
