Toleration Trait

This trait sets Tolerations over Integration pods. Tolerations allow (but do not require) the pods to schedule onto nodes with matching taints. See https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/ for more details.

The toleration should be expressed in a similar manner that of taints, i.e., Key[=Value]:Effect[:Seconds], where values in square brackets are optional.

For examples:

  • node-role.kubernetes.io/master:NoSchedule

  • node.kubernetes.io/network-unavailable:NoExecute:3000

  • disktype=ssd:PreferNoSchedule

It’s disabled by default.

This trait is available in the following profiles: Kubernetes, Knative, OpenShift.

Configuration

$ kamel run --trait toleration.[key]=[value] --trait toleration.[key2]=[value2] integration.groovy
