Functions

func DeepCopy

func DeepCopy(fs1, fs2 filesys.FileSystem) error

DeepCopy performs a deep copy of the FileSystem from fs1 to fs2.

func LoadManifests

func LoadManifests(fs *ManifestFileSystem, baseDir string, channel *loaders.Channel) error

LoadManifests takes a filesystem, a base directory path that contains the manifests and a Channel, and loads the manifests into the filesystem. The copied package manifests are copied at the root of the filesystem in a directory named the same as the package name. These manifests are not versioned. Example filesystem structure once the manifests are loaded:

/ |-- guestbook | |-- role.yaml | |-- service_account.yaml | |-- registry

|-- db.yaml
|-- frontend.yaml

func LoadPackages

func LoadPackages(fs *ManifestFileSystem, baseDir string, channel string) error

LoadPackages takes a filesystem, a base directory path and a channel name, and loads the versioned packages specified in the channel into the filesystem. The channel is based on a Channel type defined in the kubebuilder-declarative-pattern addon loaders package. Example channel:

manifests: - name: guestbook

version: 0.1.0

- name: registry

version: 0.3.0

func NewLoadedManifestFileSystem

func NewLoadedManifestFileSystem(baseDir string, channel string) (*ManifestFileSystem, error)

NewLoadedManifestFileSystem creates and returns a new ManifestFileSystem, loaded with the manifests.

func (*ManifestFileSystem) Copy

func (mfs *ManifestFileSystem) Copy(srcFile, dstFile string) (err error)

Copy reads a file from disk and copies it into manifest filesystem.

func (*ManifestFileSystem) CopyDirectory

func (mfs *ManifestFileSystem) CopyDirectory(srcDir, dest string) error
