func ValidateBase 

func ValidateBase(supportedBases []Base, base, fallbackPreferredBase Base) (Base, error)

ValidateBase attempts to validate a base if one is found, otherwise it uses the fallback base and validates that one. Returns the base it validated against or an error if one is found. Note: the selected base will be returned if there is an error to help use that for a fallback during error scenarios.

func WorkloadBases 

func WorkloadBases(now time.Time, requestedBase Base, imageStream string) ([]Base, error)

WorkloadBases returns the supported workload bases available to it at the execution time.

func (Base) DisplayString 

func (b Base) DisplayString() string

DisplayString returns the base string ignoring risk.

func (Base) Empty 

func (b Base) Empty() bool

Empty returns true if the base is empty.

func (Base) IsCompatible 

func (b Base) IsCompatible(other Base) bool

type Channel 

type Channel struct {
	Track string `json:"track,omitempty"`
	Risk  Risk   `json:"risk,omitempty"`
}

Channel identifies and describes completely an os channel.

A channel consists of, and is subdivided by, tracks and risk-levels:

  • Tracks represents the version of the os, eg "22.04".
  • Risk-levels represent a progressive potential trade-off between stability and new features.

The complete channel name can be structured as three distinct parts separated by slashes: 

<track>/<risk>

func MakeDefaultChannel

MakeDefaultChannel creates a normalized channel for the specified track with a default risk of "stable".

func ParseChannel 

func ParseChannel(s string) (Channel, error)

ParseChannel parses a string representing a channel.

func ParseChannelNormalize 

func ParseChannelNormalize(s string) (Channel, error)

func (Channel) DisplayString 

func (ch Channel) DisplayString() string

func (Channel) Empty 

func (ch Channel) Empty() bool

Empty returns true if all it's components are empty.

func (Channel) Normalize 

func (ch Channel) Normalize() Channel

func (Channel) String 

func (ch Channel) String() string

type DistroSource 

type DistroSource interface {

	Kubernetes SeriesName = "kubernetes"
)

func (SeriesName) String 

func (s SeriesName) String() string

type SupportedSeriesFunc 

type SupportedSeriesFunc = func(time.Time, string, string) (set.Strings, error)

SupportedSeriesFunc describes a function that has commonality between controller and workload types.

type WorkloadType 

type WorkloadType int

WorkloadType defines what type of workload the series is aimed at. Controllers only support Ubuntu systems. 

const (
	// ControllerWorkloadType defines a workload type that is for controllers
	// only.
	ControllerWorkloadType WorkloadType = iota

	// OtherWorkloadType workload type is for everything else.
	// In the future we might want to differentiate this.
	OtherWorkloadType

	// UnsupportedWorkloadType is used where the series does not support
	// running Juju agents.
