Types

type Function 

type Function struct {
	// `Image` specifies the function container image.
	// It can either be fully qualified, e.g.:
	//
	//	image: gcr.io/kpt-fn/set-labels
	//
	// Optionally, kpt can be configured to use a image
	// registry host-path that will be used to resolve the image path in case
	// the image path is missing (Defaults to gcr.io/kpt-fn).
	// e.g. The following resolves to gcr.io/kpt-fn/set-labels:
	//
	//	image: set-labels
	Image string `yaml:"image,omitempty"`

	// `ConfigPath` specifies a slash-delimited relative path to a file in the current directory
	// containing a KRM resource used as the function config. This resource is
	// excluded when resolving 'sources', and as a result cannot be operated on
	// by the pipeline.
	ConfigPath string `yaml:"configPath,omitempty"`

	// `ConfigMap` is a convenient way to specify a function config of kind ConfigMap.
	ConfigMap map[string]string `yaml:"configMap,omitempty"`
}

}

Git is the user-specified locator for a package on Git.

type GitLock 

type GitLock struct {
	// Repo is the git repository that was fetched.
	// e.g. 'https://github.com/kubernetes/examples.git'

	// e.g. 'master'
	Ref string `yaml:"ref,omitempty"`

	// Commit is the SHA-1 for the last fetch of the package.
	// This is set by kpt for bookkeeping purposes.
	Commit string `yaml:"commit,omitempty"`

GitLock is the resolved locator for a package on Git.

type Inventory 

type Inventory struct {
	// Namespace for the inventory resource.
	Namespace string `yaml:"namespace,omitempty"`
	// Name of the inventory resource.

	// Unique label to identify inventory resource in cluster.
	InventoryID string            `yaml:"inventoryID,omitempty"`
	Labels      map[string]string `yaml:"labels,omitempty"`
	Annotations map[string]string `yaml:"annotations,omitempty"`
}

Inventory encapsulates the parameters for the inventory resource applied to a cluster. All of the the parameters are required if any are set.

type KptFile 

type KptFile struct {
	yaml.ResourceMeta `yaml:",inline"`

	Upstream *Upstream `yaml:"upstream,omitempty"`

	// UpstreamLock is a resolved locator for the last fetch of the package.
	UpstreamLock *UpstreamLock `yaml:"upstreamLock,omitempty"`

	// Info contains metadata such as license, documentation, etc.
	Info *PackageInfo `yaml:"info,omitempty"`

	// Pipeline declares the pipeline of functions.
	Pipeline *Pipeline `yaml:"pipeline,omitempty"`

	// Inventory contains parameters for the inventory object used in apply.
	Inventory *Inventory `yaml:"inventory,omitempty"`

	// ForceDeleteReplace wipes all local changes to the package.
	ForceDeleteReplace UpdateStrategyType = "force-delete-replace"
)
