ansible - setting up inventory.ini

To setup ansible to manage your server, we can use inventory.ini. This is an example of what my inventory looks like. In the configuration file, I have place my server into a category called "app". 

At the bottom you can see that we setup the user and where our ssh-key pair can be located by ansible. 


# inventory file: hosts

[app]
34.129.197.131

[all:vars]
ansible_user=jeremy
ansible_ssh_private_key_file=~/.ssh/my-gcp-key

Once we have our inventory setup, we can simply run it. 

ansible -i inventory.ini -m ping app


We have successfully execute an adhoc ansible command. 

You can also try running shell ad hoc command

ansible -i inventory.ini -m shell -a "echo hello" app


If you run into issue where you not able to connect (maybe after a server reboot), this could be due to ssh finger printing. Try to debug by ssh into your vm and see if it prompts you for password.

ssh -i ~/.ssh/my-gcp-key jeremy@34.129.28.4

gemini cli getting file not defined error

Image
 While trying to run gemini cli on my windows linux subsystem, i bump into this error here - "/Roaming/npm/node_modules/@google/gemini-cli/node_modules/undici/lib/web/webidl/index.js:512 webidl.is.File = webidl.util.MakeTypeAssertion(File)"  "ReferenceError: File is not defined" In Node.js, there’s no built-in File (until very recent Node 20+ with experimental WHATWG APIs). So, unless polyfilled, File is undefined, leading to the ReferenceError. And to resolve this, I had to upgrade to node 22 (might work for node 20) and then I was able to run it.

Trying to run vllm without gpu will typicaly lands you into this issue. To resolve this issue: we can use set these both. Setting one does not work for me. So i had to configure both settings below:- 1.  environment variable CUDA_VISIBLE_DEVICES = "" 2. in the command line, change to use device cpu and remove  tensor-parallel-size. For example, python3 -m vllm.entrypoints.openai.api_server --port 8080 --model deepseek-ai/DeepSeek-R1 --device cpu --trust-remote-code --max-model-len 4096" References https://docs.vllm.ai/en/latest/getting_started/troubleshooting.html#failed-to-infer-device-type
