The Orion project continues its steady march to becoming the 
greatest workflow orchestration engine ever. This week, it is one step closer to production-ready with Kubernetes integration.
The new Prefect CLI command prefect orion kubernetes-manifest will automatically generate a Kubernetes manifest for:
- Orion service and its underlying REST API,
- Orion UI,
- Orion agent,
- a Kubernetes Role and RoleBinding with all necessary permissions.
Give it a try
As soon as you assign the KubernetesFlowRunner to your DeploymentSpec, Orion will deploy your flows as Kubernetes Jobs.
from prefect import flow
from prefect.deployments import DeploymentSpec
from prefect.flow_runners import KubernetesFlowRunner
@flow
def test_flow():
print("Hello from Kubernetes!")
DeploymentSpec(
flow=test_flow,
name="k8s_flow",
flow_runner=KubernetesFlowRunner(stream_output=True),
)
If you’re running Orion in Kubernetes, you don’t need to configure any networking. When the agent runs your deployment, it will create a Kubernetes job, which will start a pod running your flow.
