Workload CRD

Workloads are custom Kubernetes resources (CRDs). Tanzu Supply Chain does not provide specific Workload CRDs, instead a platform engineer declares a SupplyChain including the Kind of CRD to use as it's workload (eg SpringOneAppWorkload). The Components used in the SupplyChain define the schema ( shape) of the Workload CRD.

See SupplyChain's defines field.

Once the SupplyChain is applied to the cluster, and is valid, then the defined CRD is created on the cluster. It can be inspected:

$ kubectl get crd hostedapps.widget.com -oyaml # hostedapp is only an example
