Functions

func Resolve 

func Resolve(ctx context.Context, client *http.Client, dependency Dependency) (string, error)

Resolve returns the greatest stable release satisfying the version constraint.

func SameFile added in v0.2.0 

func SameFile(file File, artifact Artifact) bool

SameFile reports whether a published file satisfies a resolved artifact.

func SameImage added in v0.2.0 

func SameImage(published, desired Image) bool

SameImage reports whether two image records identify the same published image.

Types

type Artifact 

type Artifact struct {
	Key          string
	Name         string
	Version      string
	Architecture string
	URL          string
	ObjectKey    string
	Digest       string
	Path         string
	Size         int64
}

Artifact is one verified architecture-specific bootstrap dependency.

type Dependency 

type Dependency struct {
	Key               string
	Major             int
	Minor             int
	ReleaseStyle      releaseStyle
	Releases          string
	Architectures     map[string]string
	AssetName         string
	AssetURL          string
	ChecksumURL       string
	ChecksumName      string
	ChecksumAlgorithm string
	ObjectName        string
}

Dependency describes one version-constrained upstream artifact.

type Fetcher 

type Fetcher struct {
	Client       *http.Client
	CacheDir     string
	SourceDir    string
	AgentVersion string
	Progress     tui.Progress
	// contains filtered or unexported fields
}

Fetcher resolves and caches the canonical bootstrap dependencies.

func (*Fetcher) Download added in v0.2.0 

func (f *Fetcher) Download(ctx context.Context, artifacts []Artifact) ([]Artifact, error)

Download validates cached artifacts and downloads only missing or corrupt files.

func (*Fetcher) Fetch 

func (f *Fetcher) Fetch(ctx context.Context, architecture string) ([]Artifact, error)

Fetch downloads and verifies every dependency required by architecture.

func (*Fetcher) Resolve added in v0.2.0 

func (f *Fetcher) Resolve(ctx context.Context, architecture string) ([]Artifact, error)

Resolve selects versions and checksums without downloading artifacts.

type File added in v0.2.0 

type File struct {
	Version string `json:"version"`
	URL     string `json:"url"`
	Path    string `json:"path"`
	Digest  string `json:"digest"`
	Size    int64  `json:"size"`
}

File records one architecture-specific dependency file.

type Image added in v0.2.0 

type Image struct {
	Version string `json:"version"`
	Source  string `json:"source"`
	Path    string `json:"path"`
	Digest  string `json:"digest"`
	Size    int64  `json:"size"`
}

Image records one setup-managed OCI image.

type Manifest added in v0.2.0 

type Manifest struct {
	Version      int                        `json:"version"`
	Dependencies map[string]map[string]File `json:"dependencies"`
	Images       map[string]Image           `json:"images"`
}

Manifest records the dependency files and images published for a cluster.

func NewManifest added in v0.2.0 

func NewManifest(artifacts map[string][]Artifact, images map[string]Image) Manifest

NewManifest creates a manifest from resolved artifacts and images.

func ParseManifest added in v0.2.0 

func ParseManifest(body []byte) (Manifest, error)

ParseManifest parses and validates a dependency manifest.

func (Manifest) Marshal added in v0.2.0 

func (m Manifest) Marshal() ([]byte, error)

Marshal validates and encodes a dependency manifest deterministically.

func (Manifest) Validate added in v0.2.0 

func (m Manifest) Validate() error

Validate checks the manifest version and every published object.

type Object 

type Object struct {
	Key, Group, Version string
	Modified            time.Time
}

Object is retention metadata for one uploaded dependency object.

func Expired 

func Expired(objects []Object, now time.Time) []Object

Expired selects versions beyond the newest two when all their objects are 28 days old.
