Using Kubernetes Tolerations

Version 1.15 keyboard_arrow_down

To use the Taints and Tolerations feature of Kubernetes, you must define the tolerations override property for each Apigee hybrid component. The following components support defining tolerations:

See the Configuration property reference for more information about these components.

Apply Tolerations to individual components by adding the tolerations: configuration properties in your overrides file and then upgrading the Helm chart for the component.

See the Apigee Helm charts reference for a list of which Helm charts manage each hybrid component.

For example, to apply the tolerations to the Apigee operator deployment

  1. Add the tolerations: properties to ao: in your overrides file: 
    ao:
  tolerations:
  - key: "key1"
    operator: "Equal"
    value: "value1"
    effect: "NoExecute"
    tolerationSeconds: 3600
  2. Apply the change to the apigee-operator chart: 
    helm upgrade operator apigee-operator/ \
  --install \
  --namespace APIGEE_NAMESPACE \
  --atomic \
  -f overrides.yaml

To apply the tolerations to the Cassandra StatefulSet:

  1. Add the tolerations: properties to cassandra: in your overrides file: 
    cassandra:
  tolerations:
  - key: "key1"
    operator: "Equal"
    value: "value1"
    effect: "NoExecute"
    tolerationSeconds: 3600
  2. Apply the change to the apigee-datastore chart: 
    helm upgrade datastore apigee-datastore/ \
  --install \
  --namespace APIGEE_NAMESPACE \
  --atomic \
  -f overrides.yaml
