Prefect integrations for orchestrating and monitoring apache spark jobs on kubernetes using spark-on-k8s-operator.
## Welcome!
`prefect-spark-on-k8s-operator` is a collection of Prefect flows enabling orchestration, observation and management of `SparkApplication` custom kubernetes resources defined according to spark-on-k8s-operator CRD v1Beta2 API Spec.
Jump to [examples](#example-usage).
## Resources
For more tips on how to use tasks and flows in a Collection, check out [Using Collections](https://docs.prefect.io/collections/usage/)!
### Installation
You need to configure the kubernetes credentials as per `prefect-kubernetes` documentation.<br />
Install `prefect-spark-on-k8s-operator` with `pip`:
```bash
pip install prefect-spark-on-k8s-operator
```
Requires an installation of Python 3.7+.
We recommend using a Python virtual environment manager such as pipenv, conda or virtualenv.
These flows are designed to work with Prefect 2.0. For more information about how to use Prefect, please refer to the [Prefect documentation](https://docs.prefect.io/).
### Example Usage
#### Specify and run a SparkApplication from a yaml file
```python
import asyncio
from prefect_kubernetes.credentials import KubernetesCredentials
from prefect_spark_on_k8s_operator import (
SparkApplication,
run_spark_application, # this is a flow
)
app = SparkApplication.from_yaml_file(
credentials=KubernetesCredentials.load("k8s-creds"),
manifest_path="path/to/spark_application.yaml",
)
if __name__ == "__main__":
# run the flow
asyncio.run(run_spark_application(app))
```
