Eclipse-mosquitto "Address not available"

Question

I am new to mqtt and am trying to simply start a local instance with which I can test.

When executing

docker run -it -p 1883:1883 --restart always -v mosquitto.conf:/home/juliette/mosquito.conf --name mqtt eclipse-mosquitto:2.0.7

I get the following output:

1615963221: mosquitto version 2.0.7 starting
1615963221: Config loaded from /mosquitto/config/mosquitto.conf.
1615963221: Starting in local only mode. Connections will only be possible from clients running on this machine.
1615963221: Create a configuration file which defines a listener to allow remote access.
1615963221: Opening ipv4 listen socket on port 1883.
1615963221: Opening ipv6 listen socket on port 1883.
1615963221: Error: Address not available
1615963221: mosquitto version 2.0.7 running

and cannot connect with a mqtt-client:

mqtt sub --topic test
Server closed connection without DISCONNECT.

From what I've found the error apparently happens when no listener is configured but I did configure one, this is my mosquito.conf:

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

I also tried changing the port to 8883 because in one post someone mentioned that a larger port might solve the problem but that also didn't work.

Can someone tell me what I'm doing wrong?

remove the port 1883 from the end of the config file, you have already told it to use that port as part of the listener on the first line. — hardillb

Your startup command is close, but not correct. It should be:

docker run -it \
  -p 1883:1883 \
  --restart always \
  -v /home/juliette/mosquito.conf:/etc/mosquitto/mosquitto.conf \
  --name mqtt \
  eclipse-mosquitto:2.0.7

The config file is in /etc/mosquitto...unless they have moved it in version 2.

You might also want to add a -p 8333:8333 line for mqtts/TLS connections.

EDIT: I see up in your log file output it says that the config was loaded from /mosquitto/config/mosquitto.conf ...so if the -v /home/juliette/mosquito.conf:/etc/mosquitto/mosquitto.conf line does not work, change it to -v /home/juliette/mosquito.conf:/mosquitto/config/mosquitto.conf
