Can't set configs on docker run

I am trying to set some configs like user and password on my cassandra_exporter, however, everytime I try to mount the config on the container, I have this error mentioned below.

I tried to set those configs using -e “VARKey value” but it also didn’t work.

As I see there are many people using it, I just assume I’m doing it wrong, but I didn’t figure out how to properly use it.

The configs are currently on /tmp/config.yml, but it was in different directories before, I was just trying to move around to check permissions.

docker run --privileged --rm -ti -v /tmp/config.yml:/etc/cassandra_exporter/config.yml --name cassandra-exporter criteord/cassandra_exporter

Starting Cassandra exporter
JVM_OPTS: 
CASSANDRA_EXPORTER_CONFIG_user 
sed: cannot rename /etc/cassandra_exporter/sedjzhwca: Device or resource busy

You welcome, Btw, except if it is on purpose, you should not need the --privileged on your docker run

Either a password or your jmx on cassandra is not listening for remote connexion. You can look like at this issue https://github.com/criteo/cassandra_exporter/issues/4 in order to try it out
