Functions

func WindowsServerVersionforNTVersion

func WindowsServerVersionforNTVersion(major string, minor string) (marketingMajor, marketingMinor string, err error)

WindowsServerVersionforNTVersion returns the marketing version corresponding to an NT version.

Careful: NT versions are shared across multiple Windows products, so this function is a rough heuristic. It follows these rules for a collision:

• Only returns server versions (not desktop).
• If multiple server versions are possible, return the earliest.

Types

type Release

type Release interface {
	// ImportCompatible returns whether a distro considers two releases
	// compatible. As an example, different minor versions in Ubuntu are typically
	// not compatible, while different minor versions in centOS are.
	ImportCompatible(other Release) bool

	// AsGcloudArg returns a hyphenated identifier, as used in the `--os` flag
	// of `gcloud compute images import`. It is intended for
	// showing to users in a help message. Notably, it lacks support for
	// the -byol suffix, as that is not currently modeled.
	AsGcloudArg() string
}

Release encapsulates product and version information about the operating systems we support.

func FromComponents

func FromComponents(distro string, major string, minor string, architecture string) (r Release, e error)

FromComponents interprets the (distro, major, minor) tuple and returns a Release if the arguments are syntactically correct, and represent a release that we *may* support. The caller is responsible for verifying whether a translator is available elsewhere in the system.

func FromGcloudOSArgument

func FromGcloudOSArgument(osFlagValue string) (r Release, e error)

FromGcloudOSArgument parses the argument provided to the `--os` flag of `gcloud compute images import`, and returns a Release if it represents a release we *may* support. The caller is responsible for verifying whether a translator is available elsewhere in the system.

func FromGcloudOSArgumentMustParse

func FromGcloudOSArgumentMustParse(osFlagValue string) Release

FromGcloudOSArgumentMustParse parses the argument provided to the `--os` flag of `gcloud compute images import`, and returns a Release if it represents a release we *may* support. If osFlagValue does not parse, the call panics.
