Build models into containers

In this guide we will preload a LLM into a custom built Ollama serving image. You can follow the same steps for other models and other serving engines.

Define some values

export MODEL_URL=ollama://qwen2:0.5b

# Customize with your own image repo.
export IMAGE=us-central1-docker.pkg.dev/substratus-dev/default/ollama-builtin-qwen2-05b:latest

Build and push image. Note: building (downloading base image & model) and pushing (uploading image & model) can take a while depending on the size of the model.

git clone https://github.com/substratusai/kubeai
cd ./kubeai/images/ollama-builtin

docker build --build-arg MODEL_URL=$MODEL_URL -t $IMAGE .
docker push $IMAGE

Create a model manifest & apply into a cluster with KubeAI installed. NOTE: The only difference between an built-in model image and otherwise is the addition of the image: field.

kubectl apply -f - << EOF
