Pod Toleration

Support for specifying K8s YAML for Pod Toleration

DuploCloud supports the customization of many Kubernetes (K8s) YAML operators, such as tolerations. If you are using a Docker container, you can specify the tolerations operator configuration in the Other Container Config field in the container definition in DuploCloud

Specifying Pod Toleration

1. In the DuploCloud Portal, navigate to Kubernetes -> Services or Docker -> Services. The Services page displays.

2. Select the Service from the NAME column.

3. From the Actions menu, select Edit. The Edit Service page displays.

Example Code: tolerations operator YAML

In this example:

• If a Pod is running and a taint matching key1 exists on the node, then the Pod will not schedule the node (NoSchedule).

• If a Pod is running and a taint matching example-key exists on the node, then the Pod stays bound to the node for 6000 seconds, and then is evicted (NoExecute). If the taint is removed before that time, the Pod will not be evicted.
