Running using .my.cnf from the current directory

Thanks for the respond.
I'm using mysqld_exporter with docker.

This is the official documentation for docker: https://github.com/prometheus/mysqld_exporter/blob/main/README.md#using-docker
I've tried this:

docker run -d \
  -p 9104:9104 \
  --network my-mysql-network  \
  prom/mysqld-exporter
  --config.my-cnf=./my.cnf
49ab1417a4f779e6f77dd740ce7d767401a1d055c90f429b9b7e2e9c28ab2e35
docker: Error response from daemon: network my-mysql-network not found.
-bash: --config.my-cnf=./my.cnf: No such file or directory

And this:

docker run -d \
  -p 9104:9104 \
  --network my-mysql-network  \
  prom/mysqld-exporter
  --config.my-cnf=.my.cnf
9ce928b319b21270219a8ac1fc3281f84ed5eb89adc69541f5cfe26a2f62da08
docker: Error response from daemon: network my-mysql-network not found.
-bash: --config.my-cnf=.my.cnf: command not found

In the current directory is an my.cnf:

ls
docker-compose.yml  my.cnf

Dear maintainers/devs please fix this or update the documentation.
Thank you
