Functions

func CheckKptfileVersion 

func CheckKptfileVersion(content []byte) error

CheckKptfileVersion verifies the apiVersion and kind of the resource within the Kptfile. If the legacy version is found, the DeprecatedKptfileError is returned. If the currently supported apiVersion and kind is found, no error is returned.

func DecodeKptfile 

func DecodeKptfile(in io.Reader) (*kptfilev1.KptFile, error)

func DecodeRGFile 

func DecodeRGFile(in io.Reader) (*rgfilev1alpha1.ResourceGroup, error)

DecodeRGFile converts a string reader into structured a ResourceGroup object.

func GetPkgPathAnnotation 

func GetPkgPathAnnotation(rn *yaml.RNode) (string, error)

GetPkgPathAnnotation returns the package path annotation on a given resource.

func IsPackageDir 

func IsPackageDir(fsys filesys.FileSystem, path string) (bool, error)

IsPackageDir checks if there exists a Kptfile on the provided path, i.e. whether the provided path is the root of a package.

func IsPackageUnfetched 

func IsPackageUnfetched(path string) (bool, error)

IsPackageUnfetched returns true if a package has Upstream information, but no UpstreamLock. For local packages that doesn't have Upstream information, it will always return false. If a Kptfile is not found on the provided path, an error will be returned.

func ReadKptfile 

func ReadKptfile(fs filesys.FileSystem, p string) (*kptfilev1.KptFile, error)

ReadKptfile reads the KptFile in the given pkg. TODO(droot): This method exists for current version of Kptfile. Need to reconcile with the team how we want to handle multiple versions of Kptfile in code. One option is to follow Kubernetes approach to have an internal version of Kptfile that all the code uses. In that case, we will have to implement pieces for IO/Conversion with right interfaces.

func ReadRGFile 

func ReadRGFile(pkgPath, rgfile string) (*rgfilev1alpha1.ResourceGroup, error)

ReadRGFile reads the resourcegroup inventory in the given pkg.

func RemovePkgPathAnnotation 

func RemovePkgPathAnnotation(rn *yaml.RNode) error

RemovePkgPathAnnotation removes the package path on a given resource.

func SetPkgPathAnnotation 

func SetPkgPathAnnotation(rn *yaml.RNode, pkgPath types.UniquePath) error

SetPkgPathAnnotation sets package path on a given resource.

func Subpackages 

func Subpackages(fsys filesys.FileSystem, rootPath string, matcher SubpackageMatcher, recursive bool) ([]string, error)

Subpackages returns a slice of paths to any subpackages of the provided path. The matcher parameter decides the types of subpackages should be considered(ALL/LOCAL/REMOTE/NONE), and the recursive parameter determines if only direct subpackages are considered. All returned paths will be relative to the provided rootPath. The top level package is not considered a subpackage. If the provided path doesn't exist, an empty slice will be returned. Symlinks are ignored. TODO: For now this accepts the path as a string type. See if we can leverage the package type here.

func (k *KptfileError) Unwrap() error

type MultipleInventoryInfoError 

type MultipleInventoryInfoError struct{}

MultipleInventoryInfoError is the error returned if there are multiple inventories provided in a stream or package contained with both Kptfile and ResourceGroup objects.

func (*MultipleInventoryInfoError) Error 

func (e *MultipleInventoryInfoError) Error() string

type MultipleKfInv 

type MultipleKfInv struct{}

MultipleKfInv is the error returned if there are multiple inventories provided in a stream or package as ResourceGroup objects.

func (*MultipleKfInv) Error 

func (e *MultipleKfInv) Error() string

type MultipleResourceGroupsError 

type MultipleResourceGroupsError struct{}

MultipleResourceGroupsError is the error returned if there are multiple inventories provided in a stream or package as ResourceGroup objects.

func (*MultipleResourceGroupsError) Error 

func (e *MultipleResourceGroupsError) Error() string

type NoInvInfoError 

type NoInvInfoError struct{}

NoInvInfoError is the error returned if there are no inventory information provided in either a stream or locally.

func (*NoInvInfoError) Error 

func (e *NoInvInfoError) Error() string

type Pkg 

type Pkg struct {

	// UniquePath represents absolute unique OS-defined path to the package directory on the filesystem.
	UniquePath types.UniquePath

	// DisplayPath represents Slash-separated path to the package directory on the filesystem relative
	// to parent directory of root package on which the command is invoked.
	// root package is defined as the package on which the command is invoked by user
	// This is not guaranteed to be unique (e.g. in presence of symlinks) and should only
	// be used for display purposes and is subject to change.
	DisplayPath types.DisplayPath
	// contains filtered or unexported fields
}

Pkg represents a kpt package with a one-to-one mapping to a directory on the local filesystem.

func New 

func New(fs filesys.FileSystem, path string) (*Pkg, error)

New returns a pkg given an absolute OS-defined path. Use ReadKptfile or ReadPipeline on the return value to read meta resources from filesystem.

func (*Pkg) DirectSubpackages 

func (p *Pkg) DirectSubpackages() ([]*Pkg, error)

DirectSubpackages returns subpackages of a pkg. It will return all direct subpackages, i.e. subpackages that aren't nested inside other subpackages under the current package. It will return packages that are nested inside directories of the current package. TODO: This does not support symlinks, so we need to figure out how we should support that with kpt.

func (*Pkg) Kptfile 

func (p *Pkg) Kptfile() (*kptfilev1.KptFile, error)

Kptfile returns the Kptfile meta resource by lazy loading it from the filesytem. A nil value represents an implicit package.

func (*Pkg) LocalInventory 

func (p *Pkg) LocalInventory() (kptfilev1.Inventory, error)

LocalInventory returns the package inventory stored within a package. If more than one, or no inventories are found, an error is returned instead.

func (*Pkg) LocalResources 

func (p *Pkg) LocalResources() (resources []*yaml.RNode, err error)

LocalResources returns resources that belong to this package excluding the subpackage resources.

func (*Pkg) Pipeline 

func (p *Pkg) Pipeline() (*kptfilev1.Pipeline, error)

Pipeline returns the Pipeline section of the pkg's Kptfile. if pipeline is not specified in a Kptfile, it returns Zero value of the pipeline.

func (*Pkg) ReadRGFile 

func (p *Pkg) ReadRGFile(rgfile string) (*rgfilev1alpha1.ResourceGroup, error)

ReadRGFile returns the resourcegroup object by lazy loading it from the filesytem.

func (*Pkg) RelativePathTo 

func (p *Pkg) RelativePathTo(ancestorPkg *Pkg) (string, error)

RelativePathTo returns current package's path relative to a given package. It returns an error if relative path doesn't exist. In a nested package chain, one can use this method to get the relative path of a subpackage relative to an ancestor package up the chain. Example: rel, _ := subpkg.RelativePathTo(rootPkg) The returned relative path is compatible with the target operating system-defined file paths.

func (*Pkg) String 

func (p *Pkg) String() string

String returns the slash-separated relative path to the package.

func (*Pkg) ValidatePipeline 

func (p *Pkg) ValidatePipeline() error

Validates the package pipeline.

type RGError
