Functions

func HandleRelease

func HandleRelease(ctx context.Context, base string, client *http.Client, p Package, r Release, allReleases map[string][]Release) error

HandleRelease processes the files for a given release of the specified Package.

func ReadConfig

func ReadConfig(path string) (retval map[string]*Package, err error)

ReadConfig reads a set of Packages (as a map from package name to package configuration) from a yaml file a the selected path

Types

type Asset

type Asset struct {
	Name string
	URL  string
	// contains filtered or unexported fields
}

Asset provides an abstract interface for describing a resource which should be stored on the disk.

func CollectReleaseAssets

func CollectReleaseAssets(p Package, r Release, allReleases map[string][]Release) []Asset

func (Asset) Less

func (a Asset) Less(b Asset) bool

Less provides a method for implementing `sort.Slice` to ensure that assets are applied in the correct order.

type AssetFilter

type AssetFilter struct {
	// IncludeArtifacts is a set of regep patterns to select which artifacts
	// from a release should be downloaded and included. If no IncludeArtifacts
	// are supplied, all files from the release will be included.
	IncludeArtifacts []string `json:"include"`
	// ExcludeArtifacts is a set of regexp patterns to remove artifacts which
	// would otherwise be selected by IncludeArtifacts.
	ExcludeArtifacts []string `json:"exclude,omitempty"`

	// Rename provides a mechanism to remap artifacts from one filename to
	// another.
	Rename map[string]string
}

AssetFilter provides an interface for selecting and managing assets within a release.

func (*AssetFilter) Accept

func (af *AssetFilter) Accept(name string) string

Accept provides a method which can be supplied to `FilterAssets` to handle `IncludeArtifacts` and `ExcludeArtifacts`.

type GitHubSource

type GitHubSource struct {
	// Repo is the path to a repo in GitHub, using the "org/repo" format.
	Repo string `json:"repo"`
}

GitHubSource represents a software package which is released via GitHub releases.

type Package

type Package struct {
	// Name is a top-level directory name that the releases should be stored in.
	// This is collected from a map key in the configuration and is not directly
	// loaded from YAML.
	Name string `json:"-"`

	// If Alternatives is true, this will be considered an "alternatives"
	// collection, which contains single file alternatives for each Additional
	// item based on the latest minor (but not patch) versions of Primary.
	Alternatives bool

	// Primary is the primary source of release artifacts; collections of
	// release artifacts will be numbered based on the primary source's release
	// numbering scheme.
	Primary Source

	// Additional sources provide secondary artifacts which should be bundled
	// with the artifacts of the primary release. This can be useful (for
	// example) to select plugins which should be included with a base package.
	Additional []Source `json:",omitempty"`
}

Package represents a single deployable set of software artifacts, possibly composed of several repo-level releases.

func (*Package) String

func (p *Package) String() string

String implements fmt.Stringer.

type Release

type Release struct {
	Org     string
	Repo    string
	TagName string
	Created time.Time
	Assets  assetList //[]Asset
}

Release provides an interface for a release which contains multiple assets at the same release (TagName)

func LastN

func LastN(latestVersion string, minors int, allReleases []Release) []Release

LastN selects the last N minor releases (including all patch releases) for a given sequence of releases, which need not be sorted.

func (Release) Less

func (r Release) Less(b Release) bool

Less provides a sort on Releases by TagName.

func (Release) String

func (r Release) String() string

String implements `fmt.Stringer`.

type S3Source

type S3Source struct {
	// Bucket is the path to a Blob storage bucket
	Bucket string
	// Prefix is the path within a Blob storage bucket
	Prefix string
}

S3Source represents a set of yaml documents published to a blob storage bucket.

type Source

type Source struct {
	AssetFilter `json:",inline"`
	// GitHub represents software released on GitHub using GitHub releases.
	GitHub GitHubSource `json:"github,omitempty"`
	// S3 represents software manifests stored in an blob storage service under
	// a specified prefix. The blob paths should end with "vX.Y.Z/<asset name>"
	S3 S3Source `json:"s3,omitempty"`
	// EventingService represents the name of the service for the eventing source
	EventingService string `json:"eventingService,omitempty"`
	// IngressService represents the name of the network plugin for the ingress
	IngressService string `json:"ingressService,omitempty"`
	// Overrides provides a mechanism for modifying include/exclude (and
	// possibly other settings) on a per-release or per-minor-version basis, to
	// allow fixing up discontinuities in release patterns.
	Overrides map[string]AssetFilter `json:"overrides"`
}

Source is represents the release artifacts of a given project or repo, which provides a sequence of semver-tagged artifact collections for an individual release.

func (*Source) Accept

func (s *Source) Accept(ver string) func(name string) string

Accept determines the best acceptance function for the given version, taking into account overrides.

func (*Source) OrgRepo

func (s *Source) OrgRepo() (string, string)

OrgRepo returns the GitHub org and repo associated with this Source.

NOTE: this is totally a smell, because it's GitHub specific. The GitHub adapter outside package should probably handle this split if needed for the github library.

func (*Source) String

func (s *Source) String() string

String implements fmt.Stringer.
