mosquitto/config/mosquitto.conf is not directory. #2258

Docker under Windows 10 using WSL Ubuntu

Following instructions from DockerHub

Fresh docker pull eclipse-mosquitto (2.0.11)

Trying to mount local configuration file to /mosquitto/config/mosquitto.conf

docker run -it -p 1883:1883 -p 9001:9001 -v mosquitto.conf:/mosquitto/config/mosquitto.conf eclipse-mosquitto

Getting error

docker: Error response from daemon: source /var/lib/docker/overlay2/5dd23c2c5fbc219073fae389d71dd33a63711a1b0562afc9edf4528a52d48624/merged/mosquitto/config/mosquitto.conf is not directory.

Tried it under

Command line Windows Powewr Shell WSL ubuntu

As well as under A Macbook Pro running Big Sur and Ubuntu 21.04

This is more a Docker issue than Mosquitto issue but since it's from the official Eclipse- Foundation image it might be appropriate to post here.

in another issue I found you need to modify

mosquitto.conf:/mosquitto/config/mosquitto.conf

to the absolute real path of the config file. the right part is the container, the left is where it is on the system. For my install I modified to (looks redundant)

/mosquitto/config/mosquitto.conf:/mosquitto/config/mosquitto.conf

the conf file is in /mosquitto/config/mosquitto.conf on my system, so same on both sides of the :

I faced the same issue using docker in WSL2.

▶ If you have already installed mosquitto in your machine and you want to use system's mqtt config, just like @kcossabo mentioned, use:

docker run -it -p 1883:1883 -p 9001:9001 -v /mosquitto/config/mosquitto.conf:/mosquitto/config/mosquitto.conf eclipse-mosquitto

▶ But, if you do not have mosquitto installed,

Create mosquito.conf under current directory and add this default config:

persistence true
persistence_location /mosquitto/data/
log_dest file /mosquitto/log/mosquitto.log
allow_anonymous true
listener 1883

Use $(pwd) to mount your current directory:

docker run -it -p 1883:1883 -p 9001:9001 -v $(pwd)/mosquitto.conf:/mosquitto/config/mosquitto.conf eclipse-mosquitto

Hope this works for you.

for me this comment helped: https://github.com/docker/for-linux/issues/675#issuecomment-648992857

I was using k8s config maps and there one has a directory to be mounted, hence the target should be a directory as well. So /mosquitto/config/ instead of /mosquitto/config/mosquitto.conf

however for you in docker your command should work as long as the conf file really exists.
