Mesh-enabled Template Example Configuration 1.2¶
Working with the Cloud Side¶
In this cloud-specific section, we will set up all the configuration that is needed such as what server name to use for the cloud broker, generate the TLS keys and certs and generate the user-config.json to be used by the mesh section later on. Then start the cloud broker and client containers. Lastly, we will use our Cloud web client to verify only that the mqtt cloud broker and client containers can communicate with each other.
Configure Cloud and Mesh Brokers¶
The only configuration parameter you need to know to get this to work is the hostname of the Linux Server you want to run the Cloud MQTT Broker and client on. Ideally, this could be the same machine that VHT is installed on. This demonstration is currently running Ubuntu 18.04 and has VHT 1.2.1-1 installed.
Determining the server name is the only required configuration change needed but we need to make sure that our local DNS knows of it by resolving it to an IP address. This is important because this is exactly what your VeeaHub MEN will try to do later when we configure the mesh bridge broker to communicate with this server name which will be running the cloud broker. So as a quick test, add a unique hostname to your /etc/hostname. Then reboot your Linux box. After it comes up ping the server name you added from a different machine than your server to see if DNS knows about it. My example ping test below looks good.

The only configuration change you will have to make in this whole demonstration is to change the hostname from 'test-server' in the following 3 files to whatever the hostname of your server will be.
-
cloudx/init-config.sh
-
cloudx/docker-compose-cloud-instance.yaml
The last step of the configuration stage is to generate the Cloud Broker's TLS Keys and certs and then generate the cloudx/user-config.json.gen file using the command below. More information about usage of user-config.json file can be seen here Issue the following commands to generate the needed configuration
BASH

Open Cloud Side Client Web Interface¶
The last thing we will do on the cloud side for the moment is to test that our cloud client test web app is working.
Open a local web browser and enter URL: localhost:9090:/
Notice in the screenshot below that the output of the 'list' command shows no mesh clients yet. Also, the output of the 'stats' command shows not mesh telemetry data yet either. This is all because the Mesh MQTT broker and client services are not running as of now, but will soon be.
