# Eclipse Mosquitto Docker Image
|
|
Containers built with this Dockerfile build as source from published tarballs.
|
|
|
|
## Mount Points
|
|
Three docker volumes have been created in the image to be used for configuration, persistent storage and logs.
|
|
```
|
|
/mosquitto/config
|
|
/mosquitto/data
|
|
/mosquitto/log
|
|
```
|
|
|
|
## Running without a configuration file
|
|
Mosquitto 2.0 requires you to configure listeners and authentication before it
|
|
will allow connections from anything other than the loopback interface. In the
|
|
context of a container, this means you would normally need to provide a
|
|
configuration file with your settings.
|
|
|
|
If you wish to run mosquitto without any authentication, and without setting
|
|
any other configuration options, you can do so by using a configuration
|
|
provided in the container for this purpose:
|
|
```
|
|
docker run -it -p 1883:1883 eclipse-mosquitto:<version> mosquitto -c /mosquitto-no-auth.conf
|
|
```
|
|
|
|
## Configuration
|
|
When creating a container from the image, the default configuration values are used.
|
|
To use a custom configuration file, mount a **local** configuration file to `/mosquitto/config/mosquitto.conf`
|
|
```
|
|
docker run -it -p 1883:1883 -v <absolute-path-to-configuration-file>:/mosquitto/config/mosquitto.conf eclipse-mosquitto:<version>
|
|
```
|
|
|
|
Configuration can be changed to:
|
|
|
|
* persist data to `/mosquitto/data`
|
|
* log to `/mosquitto/log/mosquitto.log`
|
|
|
|
i.e. add the following to `mosquitto.conf`:
|
|
```
|
|
persistence true
|
|
persistence_location /mosquitto/data/
|
|
|
|
log_dest file /mosquitto/log/mosquitto.log
|
|
```
|
|
|
|
**Note**: For any volume used, the data will be persistent between containers.
|
|
|
|
## Build
|
|
Build and tag the docker image for a specific version:
|
|
```
|
|
docker build -t eclipse-mosquitto:<version> --build-arg VERSION="<version>" .
|
|
```
|
|
|
|
## Run
|
|
Run a container using the new image:
|
|
```
|
|
docker run -it -p 1883:1883 -v <path-to-configuration-file>:/mosquitto/config/mosquitto.conf -v /mosquitto/data -v /mosquitto/log eclipse-mosquitto:<version>
|
|
```
|
|
:boom: if the mosquitto configuration (mosquitto.conf) was modified
|
|
to use non-default ports, the docker run command will need to be updated
|
|
to expose the ports that have been configured.
