mosquitto-local

Creates the docker image ridomin/mosquitto-local:dev to be used when developing MQTT applications locally

It comes with a pre-bundled TLS certificate, exposing TCP and WebSockets on the following ports:

• 1883 - TCP no TLS
• 8883 - TCP with TLS
• 8080 - WebSockets no TLS
• 8443 - WebSockets with TLS

Localhost certificate

The X509 certificate has been issued by a private CA, you might need to configure your client to trust the CA

RidoFY23CA

How to use it

docker run -it --rm -p 8080:8080 -p 1883:1883 -p 8883:8883 -p 8884:8884 -p 8443:8443  ridomin/mosquitto-local:dev

Now you can connect with any compatible MQTT client:

TCP no TLS (1883)

mosquitto_pub -h localhost -p 1883 -u user -P password -t test -m hi -d

TCP with TLS (8883)

With username password

mosquitto_pub -h localhost -p 8883 -u user -P password -t test -m hi --cafile ca.crt -d

TCP with TLS and client certs (8884)

mosquitto_pub -h localhost -p 8884 --cafile ca.crt --cert mqttclient.cert.pem --key mqttclient.priv.key -t test -m hi -d

Note. mqttclient.cert provided for testing

WebSockets without TLS (8080)

Offers a web server with port details, and the ca cert: [http:/localhost:8080] (http:/localhost:8080)

WebSockets with TLS (8443)

You might need a websockets compatible client, such as IoT UX for MQTT
