Functions

func ParamsMap

func ParamsMap(instance *kudoapi.Instance, operatorVersion *kudoapi.OperatorVersion) (map[string]interface{}, error)

ParamsMap generates {{ Params.* }} map of keys and values which is later used during template rendering.

func PipesMap

func PipesMap(planName string, plan *kudoapi.Plan, tasks []kudoapi.Task, emeta *engine.Metadata) (map[string]string, error)

PipesMap generates {{ Pipes.* }} map of keys and values which is later used during template rendering.

Types

type InClusterResolver

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

InClusterResolver is a server-side package resolver for packages that are already installed in the cluster. It is a simpler version of the client-side pkg/kudoctl/packages/resolver/resolver_incluster.go. The client-side version would search the installed OperatorVersions and try to resolve any valid combination of the operator name and its app and operator versions, same as we would search in the repository. This resolver is only used to make sure that all the dependencies of an operator exist and that referenced operator versions are installed and uniquely identifiable by the passed operator name, appVersion and operatorVersion parameters (see pkg/apis/kudo/v1beta1/operatorversion_types_helpers.go::OperatorVersionName method).

func NewInClusterResolver

func NewInClusterResolver(client client.Client, ns string) *InClusterResolver

func (InClusterResolver) Resolve

func (r InClusterResolver) Resolve(name string, appVersion string, operatorVersion string) (*packages.PackageScope, error)

type Reconciler

type Reconciler struct {
	client.Client
	Discovery discovery.CachedDiscoveryInterface
	Config    *rest.Config
	Recorder  record.EventRecorder
	Scheme    *runtime.Scheme
}

Reconciler reconciles an Instance object.

func (*Reconciler) Reconcile

func (r *Reconciler) Reconcile(request ctrl.Request) (ctrl.Result, error)

Reconcile is the main controller method that gets called every time something about the instance changes

func (*Reconciler) SetupWithManager

func (r *Reconciler) SetupWithManager(
	mgr ctrl.Manager) error

SetupWithManager registers this reconciler with the controller manager
