Usage
Example below on how to use the operator for testing purposes.
from airflow import DAG
from datetime import datetime, timedelta
from notebook_op import NotebookOp
def run_notebook_op(op_name, cos_pull_archive, pipeline_outputs, pipeline_inputs):
op = NotebookOp(name=op_name,
namespace='default',

notebook=op_name,
cos_endpoint='http://object.storage:30000',
cos_bucket='test-bucket',
cos_directory='test-directory',
cos_pull_archive=cos_pull_archive,
pipeline_outputs=pipeline_outputs,
pipeline_inputs=pipeline_inputs,
image='elyra/tensorflow:1.15.2-py3',
in_cluster=True,
env_vars={'AWS_ACCESS_KEY_ID': 'minio', 'AWS_SECRET_ACCESS_KEY': 'minio123',
'GITHUB_TOKEN': 'XXXXXXXXXXXXX'},

)
return op
default_args = {
'start_date': datetime(2020, 1, 1),
'project_id' : '{{ pipeline_name }}',
'retries': 1,
'retry_delay': timedelta(minutes=3),
}
dag = DAG(
'test_dag',
default_args=default_args,

)

'community_contributions.csv',
'None'
)
notebook_op_2 = run_notebook_op('generate-overview',
'generate-overview-5244c826-ca17-493c-aeb8-e7a224f44527.tar.gz',
'community_overview.csv',
