Functions ¶

func SortPortRanges ¶

func SortPortRanges(portRanges []PortRange)

SortPortRanges sorts the given ports, first by protocol, then by number.

Types ¶

type Port ¶

type Port struct {
	Protocol string
	Number   int
}

Port identifies a network port number for a particular protocol.

NOTE(dimitern): This is deprecated and should be removed, use PortRange instead. There are a few places which still use Port, especially in apiserver/params, so it can't be removed yet.

func (Port) GoString ¶

func (p Port) GoString() string

GoString implements fmt.GoStringer.

func (Port) String ¶

func (p Port) String() string

String implements Stringer.

type PortRange ¶

type PortRange struct {
	FromPort int
	ToPort   int
	Protocol string
}

PortRange represents a single range of ports.

func CollapsePorts ¶

func CollapsePorts(ports []Port) (result []PortRange)

CollapsePorts collapses a slice of ports into port ranges.

NOTE(dimitern): This is deprecated and should be removed when possible. It still exists, because in a few places slices of Ports are converted to PortRanges internally.

func CombinePortRanges ¶

func CombinePortRanges(ranges ...PortRange) []PortRange

CombinePortRanges groups together all port ranges according to protocol, and then combines then into contiguous port ranges. NOTE: Juju only allows its model to contain non-overlapping port ranges. This method operates on that assumption.

func MustParsePortRange ¶

func MustParsePortRange(portRange string) PortRange

MustParsePortRange converts a raw port-range string into a PortRange. If the string is invalid, the function panics.

func ParsePortRange ¶

func ParsePortRange(inPortRange string) (PortRange, error)

ParsePortRange builds a PortRange from the provided string. If the string does not include a protocol then "tcp" is used. Validate() gets called on the result before returning. If validation fails the invalid PortRange is still returned. Example strings: "80/tcp", "443", "12345-12349/udp", "icmp".

func (PortRange) ConflictsWith ¶

func (a PortRange) ConflictsWith(b PortRange) bool

ConflictsWith determines if the two port ranges conflict.

func (PortRange) GoString ¶

func (p PortRange) GoString() string

func (PortRange) String ¶

func (p PortRange) String() string

func (PortRange) Validate ¶

func (p PortRange) Validate() error

IsValid determines if the port range is valid.
