Connection issue while trying to run hello world workflow

[Yaswanth Tippireddy]

Hi,

I have setup a cluster on WSL in my windows machine (Ubuntu 20.04 WSL - 16 cores, 32 GB RAM),

when I am trying to run the hello world workflow, I have been getting the following error

yaswanth@GAVLMUMLT-071:~/Devprojects/farmvibes-ai$ python -m vibe_core.farmvibes_ai_hello_world

I understand it is a networking issue, and I tried to ping /check the IP address 192.168.49.2 manually, but I cannot ping it. I have checked the ipconfig and I can't find that series in my list of virtual adapters as well.

I have tried restarting cluster, deleting the cluster and fresh installation, etc but the issue remains the same.

Please point me in the right direction to resolve this.

Hi @Yaswanth-Tippireddy,

Thanks for testing our solution. Unfortunately, WSL is not supported by FarmVibes.AI yet. My recommendation is to use a pure Ubuntu installation or a VM on azure.

You can check our documentation on how to create an Azure VM or take a look at our presentation here explaining how to set this VM up.

[Yaswanth Tippireddy]

Thanks, @brsilvarec . I'll set this up in a VM.

To ensure there is no confusion, can you edit this line in documentation/VM-SETUP.md so that others may not waste time trying WSL.

You'll need a Linux computer or Windows Subsystem for Linux in your Windows Machine.

[Bruno Silva]

Thank you for your contribution, Yaswanth. At this time, Windows Subsystem for Linux (WSL) can only be used to create the virtual machine. Unfortunately, WSL is not currently supported for running the FarmVibes-ai cluster. I will make sure to update the documentation to reflect this information more clearly
