How to use this image

Directories

Three directories have been created in the image to be used for configuration, persistent storage and logs.

/mosquitto/config
/mosquitto/data
/mosquitto/log

It is suggested to mirror this structure for your local configuration.

Configuration

When running the image, the default configuration values are used. To use a custom configuration file, create your mosquitto.conf in $PWD/mosquitto/config/mosquitto.conf, then mount the config directory to /mosquitto/config.

$ docker run -it -p 1883:1883 -v "$PWD/mosquitto/config:/mosquitto/config" eclipse-mosquitto

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: If a volume is used, the data will persist between containers.

Run

Run a container using the new image:

$ docker run -it -p 1883:1883 -v "$PWD/mosquitto/config:/mosquitto/config" -v /mosquitto/data -v /mosquitto/log eclipse-mosquitto

or:

$ docker run -it -p 1883:1883 -v "$PWD/mosquitto/config:/mosquitto/config" -v "$PWD/mosquitto/data:/mosquitto/data" -v "$PWD/mosquitto/log:/mosquitto/log" eclipse-mosquitto

Note: 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 1883 and port 8080:

$ docker run -it -p 1883:1883 -p 8080:8080 -v "$PWD/mosquitto/config:/mosquitto/config" eclipse-mosquitto

Image tags

The supported-tags list at the top of this page is authoritative. Official eclipse-mosquitto images are Alpine-based. Tag naming does not follow a generic "plain version" vs "version-alpine" split:

• 2.1.x: tags such as 2.1.2-alpine, 2.1-alpine, alpine, 2, and latest all refer to the current Alpine 2.1 image. There is no separate non-Alpine 2.1 tag.
• 2.0.x (OpenSSL): tags such as 2.0.22, 2.0.22-openssl, 2.0, 2.0-openssl, 2-openssl, and openssl refer to the Alpine 2.0 OpenSSL image (TLS-PSK and related OpenSSL features). Prefer an explicit 2.0* / *-openssl tag if you need this line; do not assume openssl alone means "latest Mosquitto".
• 1.6.x (OpenSSL): tags such as 1.6.15-openssl and 1.6-openssl refer to the Alpine 1.6 OpenSSL image.

If you are unsure which tag to use for current Mosquitto, prefer latest or a pinned 2.1*-alpine tag from the supported-tags list.
