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

• ao
• apigeeIngressGateway
• cassandra
• cassandraSchemaSetup
• cassandraSchemaValidation
• cassandraUserSetup
• connectAgent
• istiod
• logger
• mart
• metrics
• mintTaskScheduler
• redis
• runtime
• synchronizer
• udca
• Watcher

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

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

See theApigee 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 thetolerations: properties toao: in your overrides file:

   ao:tolerations:-key:"key1"operator:"Equal"value:"value1"effect:"NoExecute"tolerationSeconds:3600

2. Apply the change to theapigee-operator chart:

   helm upgrade operator apigee-operator/ \  --install \  --namespaceAPIGEE_NAMESPACE \  --atomic \  -foverrides.yaml

To apply the tolerations to the Cassandra StatefulSet:

1. Add thetolerations: properties tocassandra: in youroverrides file:

   cassandra:tolerations:-key:"key1"operator:"Equal"value:"value1"effect:"NoExecute"tolerationSeconds:3600

2. Apply the change to theapigee-datastore chart:

   helm upgrade datastore apigee-datastore/ \  --install \  --namespaceAPIGEE_NAMESPACE \  --atomic \  -foverrides.yaml
