Need info on remote execution with hub and node machines

[samagarw]

I checked the link : https://github.com/AppiumTestDistribution/appium-device-farm/wiki/Remote-Execution

But there it is mentioned hub config as :

{
"server": {
"port": 31337,
"plugin": {
"device-farm": {
"platform": "both", //If both android and iOS devices/simulator/emulators needs to be considered
"remote": ["https://1.1.1.1:4723"] //Add the remote host and port the appium server running in node machine.
}
}
}
}

How come node machine is started before the hub machine . We need to register nodes in hub machine right .

What does remote represents in this hub config .

Also in the node config why do we need to pass device-farm plugin :

appium server -ka 800 --use-plugins=device-farm --config ./node-config.json -pa /wd/hub

Also you have mentioned that hub is started on port 31337 but the .gif attached has port 4723 in url .

@samagarw You need to start the appium server in the node machine with the plugin first as the plugin will gather all the devices and maintain the session.

Remote in the hub config represent the node IPs and it will connect to those IPs to gather device information and proxy all the webdriver commands.

Gif in the readMe is just an example. Which ever port number your starting the Hub you need to access the same to view the dashboard

Hi, @saikrishna321,
I'm trying to get my hub and nodes working properly and I came across this discussion. It looks like the documentation has been updated, so I assume this is outdated. Can you confirm whether that's true or not?

If I'm understanding the hub-node connection properly, it works like this:

1. Start the hub (must be connected before nodes)
2. Start nodes with the device-farm capability hub set to the hub IP (e.g., http://1.1.1.1:4723)
3. The hub then is able to see the node and it's attached devices

It appears that it used to be the case that the nodes needed to be recorded on the hub configuration using the remote capability. But that no longer appears to be necessary (or even possible), correct?

The reason I'm asking for clarification, is that I'm having trouble with some of the functionality of the hub and I want to make sure it's not just a configuration issue on my side.

Ur understanding is right
