Types

type Context

type Context struct {
	Name           image.Registry `yaml:"name,omitempty"`
	ServiceAccount string         `yaml:"service-account,omitempty"`
	Token          gcloud.Token   `yaml:"-"`
	Src            bool           `yaml:"src,omitempty"`
}

Context holds information about a registry, to be written in a manifest file.

func GetSrcRegistry

func GetSrcRegistry(rcs []Context) (*Context, error)

GetSrcRegistry gets the source registry.

type Digest

type Digest struct {
	Hash string
	Tags []string
}

type DigestTags

type DigestTags map[image.Digest]TagSlice

DigestTags is a map where each digest is associated with a TagSlice. It is associated with a TagSlice because an image digest can have more than 1 tag pointing to it, even within the same image name's namespace (tags are namespaced by the image name).

type Image

type Image struct {
	Name image.Name `yaml:"name"`
	Dmap DigestTags `yaml:"dmap,omitempty"`
}

Image holds information about an image. It's like an "Object" in the OOP sense, and holds all the information relating to a particular image that we care about.

type ImageWithDigestSlice

type ImageWithDigestSlice struct {
	Name    string
	Digests []Digest
}

ImageWithDigestSlice uses a slice of digests instead of a map, allowing its contents to be sorted.

type Images

type Images []Image

Images is a slice of Image types.

type RegInvImage

type RegInvImage map[image.Name]DigestTags

A RegInvImage is a map containing all of the image names, and their associated digest-to-tags mappings. It is the simplest view of a Docker Registry, because the keys are just the image.Names (where each image.Name does *not* include the registry name, because we already key this by the RegistryName in MasterInventory).

The image.Name is actually a path name, because it can be "foo/bar/baz", where the image name is the string after the last slash (in this case, "baz").

func (RegInvImage) Minus

func (a RegInvImage) Minus(b RegInvImage) RegInvImage

Minus is a set operation. TODO: ST1016: methods on the same type should have the same receiver name

func (*RegInvImage) ToCSV

func (a *RegInvImage) ToCSV() string

ToCSV is like ToYAML, but instead of printing things in an indented format, it prints one image on each line as a CSV. If there is a tag pointing to the image, then it is printed next to the image on the same line.

Example: a@sha256:0000000000000000000000000000000000000000000000000000000000000000,a:1.0 a@sha256:0000000000000000000000000000000000000000000000000000000000000000,a:latest b@sha256:1111111111111111111111111111111111111111111111111111111111111111,-

func (RegInvImage) ToSet

func (a RegInvImage) ToSet() container.Set

ToSet converts a RegInvImage to a Set.

func (*RegInvImage) ToSorted

func (a *RegInvImage) ToSorted() []ImageWithDigestSlice

ToSorted converts a RegInvImage type to a sorted structure.

func (*RegInvImage) ToYAML

func (a *RegInvImage) ToYAML(o YamlMarshalingOpts) string

ToYAML displays a RegInvImage as YAML, but with the map items sorted alphabetically.

func (RegInvImage) Union

func (a RegInvImage) Union(b RegInvImage) RegInvImage

Union is a set operation.

type TagSet

type TagSet map[image.Tag]interface{}

TagSet is a set of Tags.

func (TagSet) Intersection

func (a TagSet) Intersection(b TagSet) TagSet

Intersection is a set operation.

func (TagSet) Minus

func (a TagSet) Minus(b TagSet) TagSet

Minus is a set operation.

func (TagSet) ToSet

func (a TagSet) ToSet() container.Set

ToSet converts a TagSet to a Set.

func (TagSet) Union

func (a TagSet) Union(b TagSet) TagSet

Union is a set operation.

type TagSlice

type TagSlice []image.Tag

TagSlice is a slice of Tags.

func (TagSlice) Intersection

func (a TagSlice) Intersection(b TagSlice) TagSet

Intersection is a set operation.

func (TagSlice) Minus

func (a TagSlice) Minus(b TagSlice) TagSet

Minus is a set operation.

func (TagSlice) ToTagSet

func (a TagSlice) ToTagSet() TagSet

ToTagSet converts a TagSlice to a TagSet.

func (TagSlice) Union

func (a TagSlice) Union(b TagSlice) TagSet

Union is a set operation.

type YamlMarshalingOpts

type YamlMarshalingOpts struct {
	// Render multiple tags on separate lines. I.e.,
	// prefer
	//
	//    sha256:abc...:
	//    - one
	//    - two
	//
	// over
	//
	//    sha256:abc...: ["one", "two"]
	//
	// If there is only 1 tag, it will be on one line in brackets (e.g.,
	// '["one"]').
	SplitTagsOverMultipleLines bool

	// Do not quote the digest. I.e., prefer
	//
	//    sha256:...:
	//
	// over
	//
	//    "sha256:...":
	//
	BareDigest bool
}

YamlMarshalingOpts holds options for tweaking the YAML output.
