Constants

const (
	AMD64   = "amd64"
	I386    = "i386"
	ARM     = "armhf"
	ARM64   = "arm64"
	PPC64EL = "ppc64el"
	S390X   = "s390x"

	// Older versions of Juju used "ppc64" instead of ppc64el
	LEGACY_PPC64 = "ppc64"
)

The following constants define the machine architectures supported by Juju.

Variables

var AllSupportedArches = []string{
	AMD64,
	I386,
	ARM,
	ARM64,
	PPC64EL,
	S390X,
}

AllSupportedArches records the machine architectures recognised by Juju.

var HostArch = hostArch

Override for testing.

var Info = map[string]ArchInfo{
	AMD64:   {64},
	I386:    {32},
	ARM:     {32},
	ARM64:   {64},
	PPC64EL: {64},
	S390X:   {64},
}

Info records the information regarding each architecture recognised by Juju.

Functions

func IsSupportedArch

func IsSupportedArch(arch string) bool

IsSupportedArch returns true if arch is one supported by Juju.

func NormaliseArch

func NormaliseArch(rawArch string) string

NormaliseArch returns the Juju architecture corresponding to a machine's reported architecture. The Juju architecture is used to filter simple streams lookup of tools and images.

Types

type ArchInfo

type ArchInfo struct {
	// WordSize is the architecture's word size, in bits.
	WordSize int
}

ArchInfo is a struct containing information about a supported architecture.
