Add in a health check

Now that docker 1.12 supports health checks it would be great to see it added. I'm happy to do a PR if you want

Provide an example how to "migrate" to eclipse-mosquitto

Provide an example how to migrate to the official Eclipse Mosquitto Container

Consider adding the Mosquitto repo key to the build context

At the moment, Mosquitto's APT repo key is downloaded from https://repo.mosquitto.org/debian/mosquitto-repo.gpg.key while building the docker image.

I suggest adding the verified key to docker's build context (to this git repo) and copying it into the image during build to mitigate possible security issues during build (in which the key is not verified).

Removing dependency on Q?

Given the only feature of Q you use is q.defer() is there any chance of removing this dependency?

Mozilla provides an alternative implementation.

Mosquitto logging permissions

Running on QNAP Container station.

docker run -ti --net=host -p 1884:1884 -p 9004:9004
-v /share/Containers/mosquitto-int/config:/mqtt/config:ro
-v /share/Containers/mosquitto-int/log:/mqtt/log:rw
-v /share/Containers/mosquitto-int/data/:/mqtt/data/
--name mqtt-int -d toke/mosquitto

conf file:
log_dest file /mqtt/log/mosquitto.log

I had to comment out config log path due to error.

[/share/CACHEDEV1_DATA/Containers/mosquitto-int/log] # docker logs mqtt-int

In shell I can manually write to /mqtt/log/ with no problem and on the host side the created file or folder is owned by admin.

I am somewhat new to this so am I missing something obvious?

adduser in Dockerfile recommendation.

First off... Thank you for building the Dockerfile for mosquitto!

The debian package mosquitto creates the user mosquitto.
During docker-mosquitto build the following line is printed (at least for me):

The system user `mosquitto' already exists. Exiting.
 ---> 76775d4bf147

I comment out the adduser line in the Dockerfile and built a container and tested:

brucelowther@DeepThought:~/src/Docker/docker-mosquitto$ docker run -ti -u mosquitto mosquitto:woadduser id
uid=104(mosquitto) gid=107(mosquitto) groups=107(mosquitto)

Indicates that the user is created even though the adduser line is commented out.

Confirmed this by looking at the debian package build:
mosquitto.postinst

From the postinst step, it will use the existing mosquitto uid rather than creating a uid.

Recommend flipping the two steps in the Dockerfile.

• Create the mosquitto user
• Install mosquitto package.

The reason this is important to me is that I want to match up the UID on the docker server (121) with the UID created in the container.

May be short sighted, but it works for me right now.

    adduser --uid 121 --system --disabled-password --disabled-login mosquitto  && \
    apt-get update && apt-get install -y mosquitto mosquitto-clients

Then I get UID that matches the target system.

brucelowther@DeepThought:~/src/Docker/docker-mosquitto$ docker run -ti -u mosquitto mosquitto:flipadduser id
uid=121(mosquitto) gid=65534(nogroup) groups=65534(nogroup)

I'm a novice.. hope this is clearly described.

Fix duplicate logging statement in default mosquitto config

The default mosquitto config does contain two logging statements.

Remove one and document accordingly.

I suggest to use only stdout as we are using docker.

Memory leak

The image seems to leak memory. Connecting 2 clients, but not sending traffic memory usage steadily increases from 20Mb to >800Mb over the course of an hour

Support for docker on rasberry pi

Tested locally and it's a trivial change to start from a different base image:

FROM resin/rpi-raspbian

Happy to submit a merge request if it's something you want to support?

Sonoff couldn't connect to MQTT

Hi,

I installed the latest toke Mosquito by docker at my Synology NAS.
Mosquitto is running normal, and I could connect with Domoticz. But isn't possible to connect MQTT with Sonoff Tasmota 6.1.1.c. The log at Sonoff replay's

11:49:12 MQT: Verbinding mislukt naar 192.XXX.XXX.XXX:1883, rc -2. Opnieuw proberen over 10 sec

Could anyone help me with this problem?

Add Client tools

For debugging purpose, it would be nice if the client tools would be available. They are included in the upstream repro. Thus, it would be easy to add them

Not able to ping containers within the same network.

Hi,

I have created 2 containers using the toke/mosquitto docker file. Both are running in the same network (not the default bridge, but in the user defined network called my_network)
When i try to ping the containers... it says ping : not found
Please have a look at it.

[Question] Set username and password for brokerconnection

Is there an easy way to start this container with an username and password for the broker connection configured? Let any security issues aside, i need that for testing. Thx.

Bug when docker build is executed.

In Step 6/14, the following error appears:

Failure to write to folder when loaded using 'run' instructions.

Hi there. Thanks for making it super-easy for me to configure docker images with Mosquitto. In the end I'll be creating my own images, but this provides a really valuable starting point.

I find the following issue when launching and closing the image, though. It appears not to be able to write to the proper location (although it's loading, I guess the relevant folders are read only). The broker comes up and is functional, however.

This is following the simple 'run' instructions at https://github.com/toke/docker-mosquitto

I guess changing the conf to not employ persistence or logging would eliminate these.
