KFP extension modules

kfp.onprem module

kfp.onprem.mount_pvc(pvc_name='pipeline-claim', volume_name='pipeline', volume_mount_path='/mnt/pipeline')[source]

Modifier function to apply to a Container Op to simplify volume, volume mount addition and enable better reuse of volumes, volume claims across container ops.


train = train_op(...)
train.apply(mount_pvc('claim-name', 'pipeline', '/mnt/pipeline'))

kfp.gcp module

Extension module for KFP on GCP deployment.

kfp.gcp.add_gpu_toleration(toleration: kubernetes.client.models.v1_toleration.V1Toleration = {'effect': 'NoSchedule', 'key': 'nvidia.com/gpu', 'operator': 'Equal', 'toleration_seconds': None, 'value': 'true'})[source]

An operator that configures the GKE GPU nodes in a container op.

Parameters:toleration – toleration to pods, default is the nvidia.com/gpu label.
kfp.gcp.use_gcp_secret(secret_name='user-gcp-sa', secret_file_path_in_volume=None, volume_name=None, secret_volume_mount_path='/secret/gcp-credentials')[source]

An operator that configures the container to use GCP service account by service account key stored in a Kubernetes secret.

For cluster setup and alternatives to using service account key, check https://www.kubeflow.org/docs/gke/authentication-pipelines/.

kfp.gcp.use_preemptible_nodepool(toleration: kubernetes.client.models.v1_toleration.V1Toleration = {'effect': 'NoSchedule', 'key': 'preemptible', 'operator': 'Equal', 'toleration_seconds': None, 'value': 'true'}, hard_constraint: bool = False)[source]

An operator that configures the GKE preemptible in a container op.

  • toleration – toleration to pods, default is the preemptible label.
  • hard_constraint – the constraint of scheduling the pods on preemptible nodepools is hard. (Default: False)
kfp.gcp.use_tpu(tpu_cores: int, tpu_resource: str, tf_version: str)[source]

An operator that configures GCP TPU spec in a container op.


kfp.aws module

kfp.aws.use_aws_secret(secret_name='aws-secret', aws_access_key_id_name='AWS_ACCESS_KEY_ID', aws_secret_access_key_name='AWS_SECRET_ACCESS_KEY', aws_region=None)[source]

An operator that configures the container to use AWS credentials.

AWS doesn’t create secret along with kubeflow deployment and it requires users to manually create credential secret with proper permissions.

apiVersion: v1
kind: Secret
  name: aws-secret
type: Opaque

kfp.azure module


An operator that configures the container to use Azure user credentials.

The azcreds secret is created as part of the kubeflow deployment that stores the client ID and secrets for the kubeflow azure service principal.

With this service principal, the container has a range of Azure APIs to access to.
