Tolerations PPS

Learn how to use tolerations in PPS to allow node taints.

February 22, 2024

Spec #

This is a top-level attribute of the pipeline spec.

{
    "pipeline": {...},
    "transform": {...},
    "tolerations": [
    {
      "key": "dedicated",
      "operator": "EXISTS",
      "effect": "NO_SCHEDULE"
    }
  ],
    ...
}

Behavior #

Pipeline tolerations enable you to run a pipeline on a node that has a taint.

  • You can have as many tolerations as you’d like, or none at all.
  • Taints behave almost exactly like the Kuberentes API, with the exception of some enums such as Exists and DoesNotExist being replaced with Golang equivalents like EXISTS and DOES_NOT_EXIST.
