var RewriteManifests = featureflag.New("RewriteManifests", featureflag.Bool(true))

RewriteManifests controls whether we rewrite manifests Because manifest rewriting converts everything to and from YAML, we normalize everything by doing so

Types

type AssetBuilder

type AssetBuilder struct {
	ContainerAssets []*ContainerAsset
	FileAssets      []*FileAsset
	AssetsLocation  *kops.Assets
	// TODO we'd like to use cloudup.Phase here, but that introduces a go cyclic dependency
	Phase string

	// KubernetesVersion is the version of kubernetes we are installing
	KubernetesVersion semver.Version
}

AssetBuilder discovers and remaps assets.

func NewAssetBuilder

func NewAssetBuilder(cluster *kops.Cluster, phase string) *AssetBuilder

NewAssetBuilder creates a new AssetBuilder.

func (*AssetBuilder) RemapFileAndSHA

func (a *AssetBuilder) RemapFileAndSHA(fileURL *url.URL) (*url.URL, *hashing.Hash, error)

RemapFileAndSHA returns a remapped url for the file, if AssetsLocation is defined. It also returns the SHA hash of the file.

func (*AssetBuilder) RemapFileAndSHAValue

func (a *AssetBuilder) RemapFileAndSHAValue(fileURL *url.URL, shaValue string) (*url.URL, error)

RemapFileAndSHAValue is used exclusively to remap the cni tarball, as the tarball does not have a sha file in object storage.

func (*AssetBuilder) RemapImage

func (a *AssetBuilder) RemapImage(image string) (string, error)

RemapImage normalizes a containers location if a user sets the AssetsLocation ContainerRegistry location.

func (*AssetBuilder) RemapManifest

func (a *AssetBuilder) RemapManifest(data []byte) ([]byte, error)

RemapManifest transforms a kubernetes manifest. Whenever we are building a Task that includes a manifest, we should pass it through RemapManifest first. This will: * rewrite the images if they are being redirected to a mirror, and ensure the image is uploaded

type ContainerAsset

type ContainerAsset struct {
	// DockerImage will be the name of the container we should run.
	// This is used to copy a container to a ContainerRegistry.
	DockerImage string
	// CanonicalLocation will be the source location of the container.
	CanonicalLocation string
}

ContainerAsset models a container's location.

type FileAsset

type FileAsset struct {
	// DownloadURL is the URL from which the cluster should download the asset.
	DownloadURL *url.URL
	// CanonicalURL is the canonical location of the asset, for example as distributed by the kops project
	CanonicalURL *url.URL
	// SHAValue is the SHA hash of the FileAsset.
	SHAValue string
}

FileAsset models a file's location.
