# Eclipse Mosquitto Docker Image
|
|
Containers built with this Dockerfile build from a source tarball "mosq.tar.gz"
|
|
placed in the local directory. Running `make localdocker` from the root of the
|
|
repository will generate the source tar and build the docker image.
|
|
|
|
## Mount Points
|
|
A docker mount point has been created in the image to be used for configuration.
|
|
```
|
|
/mosquitto/config
|
|
```
|
|
|
|
Two docker volumes have been created in the image to be used for persistent storage and logs.
|
|
```
|
|
/mosquitto/data
|
|
/mosquitto/log
|
|
```
|
|
|
|
## User/Group
|
|
|
|
The image runs mosquitto under the mosquitto user and group, which are created
|
|
with a uid and gid of 1883.
|
|
|
|
## 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>
|
|
```
|
|
|
|
: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, for example if you use port 8080
|
|
for websockets as well as port 1883:
|
|
|
|
```
|
|
docker run -it -p 1883:1883 -p 8080:8080 -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.
