do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

# Spark Operator V1beta2 1.0.0 # spark-operator-v1beta2-1.0.0-2.4.4
This is a hardened version of the upstream spark-operator/spark-operator:v1beta2-1.0.0-2.4.4 image. This is NOT meant to be deployed as is, rather imported and usesd as a base container. An example of some containers that will rely on this are the jupyter notebook containers as well as some others for the Kubeflow deployment.
No chart or deployment instructions will be made available for this image unless there is a need to deploy this container as-is
To test, run `make build` then `make run`.
To compare to unhardened container, run `make run-original`
