Review: What Workloads Can I Deploy?
In Harness, a managed workload is a Deployment, StatefulSet, or DaemonSet object deployed and managed to steady state.
Harness Canary and Blue/Green Workflow default steps support a single Deployment workload as a managed entity.
Rolling Workflow default steps support Deployment, StatefulSet, or DaemonSet as managed workloads, but not Jobs.
You can deploy any Kubernetes workload in any Workflow type by using a Harness annotation to make it unmanaged (harness.io/direct-apply).
The Apply Step can deploy any workloads or objects in any Workflow type as a managed workload.
OpenShift: Harness supports OpenShift DeploymentConfig in OpenShift clusters as a managed workload across Canary, Blue Green, and Rolling deployment strategies. Please use apiVersion: apps.openshift.io/v1 and not apiVersion: v1.
