Running Lyra in Kubernetes controller mode

Run Lyra in Kubernetes controller mode if you want Lyra to continuously apply a workflow and make sure that your resources exist in a desired state.

Before you run Lyra in controller mode, make sure you’ve set up the Kubernetes command-line tool.

Important: Deploying a workflow creates real resources and could incur a charge from your cloud provider.

To run Lyra in controller mode:

1. Install the Lyra workflow CustomResourceDefinition (CRD):

   kubectl apply -f k8s/lyra_v1alpha1_workflow_crd.yaml
   

2. Start Lyra in controller mode:

   ./build/bin/lyra controller --debug
   

3. Open a second Terminal window and create a Workflow resource:

   kubectl apply -f k8s/vpc-workflow.yaml
   

4. Inspect the resource:

   kubectl get workflows
   

5. (Optional) Delete the resources associated with the workflow:

   kubectl delete workflow vpc-workflow
   

Note: The tag data for Kubernetes workflows is specified in the data section of k8s/vpc-workflow.yaml in your Lyra directory.
