Openshift Pods Driver

Selecting the openshift pods driver adds the following options to the providers section of the configuration.

providers.[openshiftpods]
Type: list

The Openshift Pods driver is similar to the Openshift driver, but it only supports pod label. This enables using an unprivileged service account that doesn’t require the self-provisioner role.

Example:

providers:
  - name: cluster
    driver: openshiftpods
    context: unprivileged-context-name
    pools:
      - name: main
        labels:
          - name: openshift-pod
            image: docker.io/fedora:28

providers.[openshiftpods].context (required)

Name of the context configured in kube/config.

Before using the driver, Nodepool services need a kube/config file manually installed. Make sure the context is present in oc config get-contexts command output.

providers.[openshiftpods].launch-retries
Default: 3

The number of times to retry launching a pod before considering the job failed.

providers.[openshiftpods].max-pods

providers.[openshiftpods].pools
Type: list

A pool defines a group of resources from an Openshift provider.

providers.[openshiftpods].pools.name (required)

The project’s (namespace) name that will be used to create the pods.

providers.[openshiftpods].pools.node-attributes
Type: dict

A dictionary of key-value pairs that will be stored with the node data in ZooKeeper. The keys and values can be any arbitrary string.

providers.[openshiftpods].labels
Type: list

Each entry in a pool`s labels section indicates that the corresponding label is available for use in this pool.

Each entry is a dictionary with the following keys
