Following these two tutorials (https://www.anavi.org/article/182/ and http://wei-meilin.blogspot.tw/2014/05/red-hat-openshift-xpaas-simple-mqtt.html) I have installed a MQTT Broker using JBoss Fuse.
Although my mqtt-container disappears after a while (I don't know why) I can make a port-forwarding and test the broker.
But I would like to know how to connect directly to the broker. Do you know how to do it?
I have tried this tutorial (http://training.runcloudrun.com/advanced/16-Network-and-Protocols.md.html - AMQ Example) but I don't have access to "/var/lib/openshift/.httpd.d/sniproxy.cfg"
I am the author of the first tutorial that you pointed out. If you want to use MQTT without local port forwarding please have a look at the remark at the article on my blog and the AMQ cartridge that demonstrates the SNI features:
The port forwarding is not convenient for real life cases, especially if the MQTT clients are working on embedded devices such as microcontrollers and it is recommended to use a SNI Proxy as explained here: http://training.runcloudrun.com/advanced/16-Network-and-Protocols.md.html
I was using Online Openshift and that feature is only available for Enterprise edition.
Why doesn't Openshift have this feature (complete) in the Online mode?
One way to work around is to use the mqtt over websocket feature with a DIY cartridge. See the SO question "How can I access socket through Openshift" for some pointers to further details about how to run websocket on openshift.
The mosquitto seems to have implemented the websocket feature though I have not verified by testing it out.
