Functions

func DeploymentCreator 

func DeploymentCreator(workflow *operatorapi.SonataFlow, plf *operatorapi.SonataFlowPlatform) (client.Object, error)

DeploymentCreator is an objectCreator for a base Kubernetes Deployments for profiles that need to deploy the workflow on a vanilla deployment. It serves as a basis for a basic Quarkus Java application, expected to listen on http 8080.

func EnsureDeployment

Types

type MutateVisitor 

type MutateVisitor func(object client.Object) controllerutil.MutateFn

MutateVisitor is a visitor function that mutates the given object before performing any updates in the cluster. It gets called after the objectEnforcer reference.

The defaultObjectEnsurer will call the returned MutateVisitor function after creating the given object structure, so callers is ensured to have the default reference of the given object.

Usually you can safely do `object.(*<kubernetesType>).Spec...` since you control the ObjectCreator.

Example: `object.(*appsv1.Deployment).Spec.Template.Name="myApp"` to change the pod's name.

func DeploymentMutateVisitor 

func DeploymentMutateVisitor(workflow *operatorapi.SonataFlow, plf *operatorapi.SonataFlowPlatform) MutateVisitor

func ImageDeploymentMutateVisitor 

func ImageDeploymentMutateVisitor(workflow *operatorapi.SonataFlow, image string) MutateVisitor

ImageDeploymentMutateVisitor creates a visitor that mutates a vanilla Kubernetes Deployment to apply the given image in the DefaultContainerName container Only overrides the image if .spec.podTemplate.container.Image is empty.

func ManagedPropertiesMutateVisitor 

func ManagedPropertiesMutateVisitor(ctx context.Context, catalog discovery.ServiceCatalog,
	workflow *operatorapi.SonataFlow, plf *operatorapi.SonataFlowPlatform, userProps *corev1.ConfigMap) MutateVisitor

func RolloutDeploymentIfCMChangedMutateVisitor 

func RolloutDeploymentIfCMChangedMutateVisitor(workflow *operatorapi.SonataFlow, userPropsCM *corev1.ConfigMap, managedPropsCM *corev1.ConfigMap) MutateVisitor

RolloutDeploymentIfCMChangedMutateVisitor forces a pod refresh if the workflow definition suffered any changes. This method can be used as an alternative to the Kubernetes ConfigMap refresher.
