Karpenter add-on: support taints and multiple provisioners #383

Closed otterley closed 2 years ago

otterley commented 2 years ago

Describe the feature

Support node taints and multiple provisioners in the Karpenter add-on.

Use Case

Taints are the key mechanism by which Karpenter can select which Provisioner should be associated with a scheduled Pod. Without support for such taints, only one Provisioner associated with a cluster will ever be used.

For example, the customer might want to schedule some pods only onto instances with GPUs.

@otterley - I'm working through this for a PR and have taints implemented in my working branch so far.

For the second part of your request, are you referring to support for multiple providers or multiple provisioners?

otterley commented 2 years ago

Provisioners - sorry for the confusion.

I figured as much, but wanted to confirm. Thanks!
