Documentation

Overview

The solver package is responsible for constructing a taskqueue based on the set of resources that should be applied. This involves setting up the appropriate sequence of apply, wait and prune tasks so any dependencies between resources doesn't cause a later apply operation to fail. Currently this package assumes that the resources have already been sorted in the appropriate order. We might want to consider moving the sorting functionality into this package.

Types

type Options

type Options struct {
	ReconcileTimeout       time.Duration
	Prune                  bool
	DryRun                 bool
	PrunePropagationPolicy metav1.DeletionPropagation
	PruneTimeout           time.Duration
}

type TaskQueueSolver

type TaskQueueSolver struct {
	ApplyOptions *apply.ApplyOptions
	PruneOptions *prune.PruneOptions
	InfoHelper   info.InfoHelper
}

func (*TaskQueueSolver) BuildTaskQueue

func (t *TaskQueueSolver) BuildTaskQueue(ro resourceObjects,
	o Options) chan taskrunner.Task

BuildTaskQueue takes a set of resources in the form of info objects and constructs the task queue. The options parameter allows customization of how the task queue are built.
