Functions

func BuildPipelinesFallback

func BuildPipelinesFallback() []string

Fallbacks: When a new method is added to an interface to provide to provide information that isn't available for older implementations, the older methods should return a fallback/default value by calling the appropriate function from below. Example: Exports() simply returns "assembler" for older image type implementations that didn't produce v1 manifests that have named pipelines.

func ExportsFallback

func ExportsFallback() []string

func GetHostDistroName

func GetHostDistroName() (string, error)

GetHostDistroName returns the name of the host distribution, such as "fedora-32" or "rhel-8.2". It does so by reading the /etc/os-release file.

func PayloadPackageSets

func PayloadPackageSets() []string

func PayloadPipelinesFallback

func PayloadPipelinesFallback() []string

Types

type Arch

type Arch interface {
	// Returns the name of the architecture.

func (m BootMode) String() string

type Distro

	// Returns the name of the distro.
	Name() string

	// Returns the release version of the distro. This is used in repo
	// files on the host system and required for the subscription support.

	// by this distro.
	GetArch(arch string) (Arch, error)
}

A Distro represents composer's notion of what a given distribution is.

type ID

type ID struct {
	Name         string
	MajorVersion int
	// MinorVersion is -1 if not specified
	MinorVersion int
}

ID represents a distro name and version

func ParseID

func ParseID(idStr string) (*ID, error)

ParseID parses a distro name and version from a Distro ID string. This is the generic parser, which is used by all distros as the base parser.

Limitations: - the distro name must not contain a dash
