Types

type ContainerResourcesSelector

type ContainerResourcesSelector struct {
	// Type information of the resources to consider.
	resid.Gvk `json:",inline,omitempty"`
	// Namespace of the resources to consider.
	Namespace string `json:"namespace,omitempty"`
	// Name of the resources to consider.
	Name string `json:"name,omitempty"`
	// Annotation selector of resources to consider.
	AnnotationSelector string `json:"annotationSelector,omitempty"`
	// Label selector of resources to consider.
	LabelSelector string `json:"labelSelector,omitempty"`
	// Path to the list of containers.
	Path string `json:"path,omitempty"`
	// Create container resource specifications even if the original object does not contain them.
	CreateIfNotPresent bool `json:"create,omitempty"`
	// Regular expression matching the container name.
	ContainerName string `json:"containerName,omitempty"`
}

ContainerResourcesSelector identifies zero or more container resources specifications. NOTE: This object is basically a combination of a Kustomize FieldSpec and a Selector.

func DefaultContainerResourcesSelectors

func DefaultContainerResourcesSelectors() []ContainerResourcesSelector

DefaultContainerResourcesSelectors returns the default container resource selectors. These selectors match the default role created by the `grant_permissions` code.

type Generator

type Generator struct {
	// The definition of the application to generate an experiment for.
	Application redskyappsv1alpha1.Application
	// ContainerResourcesSelectors are the selectors for determining what application resources to scan for resources lists.
	ContainerResourcesSelectors []ContainerResourcesSelector
	// ReplicaSelectors are the selectors for determining what application resources to scan for desired replica counts.
	ReplicaSelectors []ReplicaSelector
	// contains filtered or unexported fields
}

Generator generates an application experiment.

func NewGenerator

func NewGenerator(fs filesys.FileSystem) *Generator

Create a new generator.

func (*Generator) Generate

func (g *Generator) Generate() (*corev1.List, error)

Generate scans the application and produces a list of Kubernetes objects representing an the experiment

func (*Generator) SetDefaultSelectors

func (g *Generator) SetDefaultSelectors()

SetDefaultSelectors adds the default selectors to the generator.

type ReplicaSelector

type ReplicaSelector struct {
	// Type information of the resources to consider.
	resid.Gvk `json:",inline,omitempty"`
	// Namespace of the resources to consider.
	Namespace string `json:"namespace,omitempty"`
	// Name of the resources to consider.
	Name string `json:"name,omitempty"`
	// Annotation selector of resources to consider.
	AnnotationSelector string `json:"annotationSelector,omitempty"`
	// Label selector of resources to consider.
	LabelSelector string `json:"labelSelector,omitempty"`
	// Path to the replica field.
	Path string `json:"path,omitempty"`
	// Create container resource specifications even if the original object does not contain them.
	CreateIfNotPresent bool `json:"create,omitempty"`
}

ReplicaSelector identifies zero or more replica specifications. NOTE: This object is basically a combination of a Kustomize FieldSpec and a Selector.

func DefaultReplicaSelectors

func DefaultReplicaSelectors() []ReplicaSelector

DefaultReplicaSelectors returns the default replica selectors. These selectors match the default role created by the `grant_permissions` code.
