Hello,
The broker doesn't start, because it can't find its configuration file /opt/emqx/etc/emqx.conf. Could you please check if there is emqx.conf file in /path/to/mqtt/etc directory?

you mean that i have to create the emqx.conf manual ?

Yes, this file is edited by the user. You can extract the default /opt/emqx/etc/emqx.conf from the container.
But our docker image actually supports getting configuration from the environment variables: https://docs.emqx.io/en/broker/v4.3/configuration/environment-variable.html
Instead of creating /path/to/mqtt/etc:/opt/emqx/etc volume, you can just set the environment variables.
