func CheckDeployment

func CheckDeployment(deployment *appsv1.Deployment) error

CheckDeployment checks whether the given Deployment is healthy. A deployment is considered healthy if the controller observed its current revision and if the number of updated replicas is equal to the number of replicas.

func CheckJob

func CheckJob(job *batchv1.Job) error

CheckJob checks whether the given Job is healthy. A Job is considered healthy if its `JobFailed` condition is missing or has status `False`.

func CheckManagedResource

func CheckManagedResource(mr *v1alpha1.ManagedResource) error
