Functions

func IsRouteNoHostError

func IsRouteNoHostError(err error) bool

func RenderChart

func RenderChart(chartPath, namespace, kubeVersion string, values interface{}) (map[string][]manifest.Manifest, map[string]interface{}, error)

RenderChart renders the helm charts, returning a map of rendered templates. key names represent the chart from which the template was processed. Subcharts will be keyed as <root-name>/charts/<subchart-name>, e.g. istio/charts/galley. The root chart would be simply, istio.

func SortByKind

func SortByKind(manifests []manifest.Manifest) []manifest.Manifest

SortByKind sorts manifests in InstallOrder

Types

type ManifestProcessor

type ManifestProcessor struct {
	common.ControllerResources
	PatchFactory *PatchFactory
	// contains filtered or unexported fields
}

func NewManifestProcessor

func NewManifestProcessor(controllerResources common.ControllerResources, patchFactory *PatchFactory,
	appInstance, appVersion string, owner types.NamespacedName,
	preprocessObjectFunc func(ctx context.Context, obj *unstructured.Unstructured) (bool, error),
	postProcessObjectFunc func(ctx context.Context, obj *unstructured.Unstructured) error,
	preprocessObjectForPatchFunc func(ctx context.Context, oldObj, newObj *unstructured.Unstructured) (*unstructured.Unstructured, error),
) *ManifestProcessor

func (*ManifestProcessor) ProcessManifest

func (p *ManifestProcessor) ProcessManifest(ctx context.Context, man manifest.Manifest, component string) (madeChanges bool, allErrors []error)

func (*ManifestProcessor) ProcessManifests

func (p *ManifestProcessor) ProcessManifests(ctx context.Context, manifests []manifest.Manifest, component string) (madeChanges bool, err error)

type Patch

type Patch interface {
	Apply(ctx context.Context) (*unstructured.Unstructured, error)
}

Patch represents a "patch" for an object

type PatchFactory

type PatchFactory struct {
	// contains filtered or unexported fields
}

PatchFactory wraps the objects needed to create Patch objects.

func NewPatchFactory

func NewPatchFactory(k8sClient client.Client) *PatchFactory

NewPatchFactory creates a new PatchFactory

func (*PatchFactory) CreatePatch

func (p *PatchFactory) CreatePatch(oldObj, newObj *unstructured.Unstructured) (Patch, error)

CreatePatch creates a patch based on the current and new versions of an object

type SortOrder

type SortOrder []string

SortOrder is an ordering of Kinds.

var InstallOrder SortOrder = []string{
	"Namespace",
	"NetworkPolicy",
	"ResourceQuota",
	"LimitRange",
	"PodSecurityPolicy",
	"PodDisruptionBudget",
	"Secret",
	"ConfigMap",
	"StorageClass",
	"PersistentVolume",
	"PersistentVolumeClaim",
	"ServiceAccount",
	"CustomResourceDefinition",
	"ClusterRole",
	"ClusterRoleList",
	"ClusterRoleBinding",
	"ClusterRoleBindingList",
	"Role",
	"RoleList",
	"RoleBinding",
	"RoleBindingList",
	"Service",
	"DaemonSet",
	"Pod",
	"ReplicationController",
	"ReplicaSet",
	"Deployment",
	"HorizontalPodAutoscaler",
	"StatefulSet",
	"Job",
	"CronJob",
	"Ingress",
	"APIService",
}

InstallOrder is the order in which manifests should be installed (by Kind).

Those occurring earlier in the list get installed before those occurring later in the list.

var UninstallOrder SortOrder = []string{
	"APIService",
	"Ingress",
	"Service",
	"CronJob",
	"Job",
	"StatefulSet",
	"HorizontalPodAutoscaler",

	"Secret",
	"PodDisruptionBudget",
	"PodSecurityPolicy",
	"LimitRange",
	"ResourceQuota",
	"NetworkPolicy",
	"Namespace",
}

UninstallOrder is the order in which manifests should be uninstalled (by Kind).

Those occurring earlier in the list get uninstalled before those occurring later in the list.
