Complex vLLM

Example deployment yamls for vLLM deployments with konduktor serve

This example also demonstrates the creation and use of --kind=env secrets using konduktor secret create. This is required for some models such as meta-llama/Meta-Llama-3.1-8B-Instruct, which require Hugging Face tokens for authentication.

Prerequisites

Setup

1. Create a --kind=env secret for your HF token called my-hf-token

$ konduktor secret create --kind=env --inline HUGGING_FACE_HUB_TOKEN=hf_ABC123 my-hf-token

2. Check that the secret was properly created with:

$ konduktor secret list

For more details, check out the setup of secrets here.
