|
||
|
||
```sh
|
||
mqtt sub -h moritzgraf.de -p 30024 --user sender -pw <password> -t demo
|
||
############# general mqtt
|
||
# get nodeport of mosquitto
|
||
kubectl get svc mosquitto -n datalab
|
||
# for password see `cat ../k8s/datalab/mosquitto.secret.yml`
|
||
# subscribe to topic
|
||
❯ mqtt sub -h moritzgraf.de -p 30024 --user sender -pw <password> -t demo
|
||
# publish a msg in different shell
|
||
❯ mqtt pub -h moritzgraf.de -p 30024 --user sender -pw <password> -m "HEllo" -t demo
|
||
```
|
||
|
||
#### paho
|
||
|
||
