Error creating backup password file "/mqtt_passwd.tmp", not continuing.

Hi guys,

I hope you are all doing great :)

I am trying to create a username and password. The following command,

docker run --rm -it \
 -u $(id -u ${USER}):$(id -g ${USER}) \
 -v $(pwd)/mosquitto.conf:/mosquitto/config/mosquitto.conf \
 -v $(pwd)/mqtt_passwd.txt:/mqtt_passwd \
 eclipse-mosquitto mosquitto_passwd -b /mqtt_passwd zuppif test123

gives Error creating backup password file "/mqtt_passwd.tmp", not continuing.

Where mqtt_passwd.txt is an empty txt file.

Thanks

As a workaround, try:

docker run --rm -it \
 -u $(id -u ${USER}):$(id -g ${USER}) \
 -v $(pwd)/mosquitto.conf:/mosquitto/config/mosquitto.conf \
 -v $(pwd)/mqtt_passwd.txt:/mqtt_passwd \
 -v $(pwd)/mqtt_passwd.txt:/mqtt_passwd.tmp \
 eclipse-mosquitto mosquitto_passwd -b /mqtt_passwd zuppif test123
