gpu-Provisioner is an Azure Karpenter provider implementation for Karpenter machine API. It leverages the machine CRD introduced by Karpenter to orchestrate the GPU VM provisioning and its lifecycle management in a standard AKS cluster.
It implements the cloud provider interfaces to realize the following abstraction:
machine -> AKS agent pool (with vmss and a hard limit of VM count to 1)
- An Azure subscription.
- An AKS cluster with OIDC addon installed. Please refer to the Karpenter installation guide for more details.
Please check the installation guidance here.
After deploying the controller successfully, one can apply the yaml in /examples to create a machine CR. A real node will be created and added to the cluster by the controller.
- The gpu-provisioner assumes the Machine CR name is equal to the agent pool name. Hence, the machine CR name must be 1-11 characters in length, start with a letter, and the only allowed characters are letters and numbers.
- The machine CR needs to have a label with key
kaito.sh/workspace.
