func NewDirectoryProvider 

func NewDirectoryProvider(ctx context.Context, path string, mopts ...ManifestOption) (Provider, error)

NewDirectoryProvider attempts to parse a provided path as a Unikraft "microlibirary" directory

func NewGitHubProvider 

func NewGitHubProvider(ctx context.Context, path string, mopts ...ManifestOption) (Provider, error)

NewGitHubProvider attempts to parse the input path as a location provided on GitHub. Additional context for authentication is necessary to use this provider if the location is held within a private repository. Otherwise we can both probe GitHub's API as well as exploit the fact that it is a Git repository to retrieve information and deliver information as a Manifest format.

func NewGitProvider 

func NewGitProvider(ctx context.Context, path string, mopts ...ManifestOption) (Provider, error)

NewGitProvider attempts to parse a provided path as a Git repository

func NewManifestIndexProvider 

func NewManifestIndexProvider(ctx context.Context, path string, mopts ...ManifestOption) (Provider, error)

NewManifestIndexProvider accepts an input path which is checked against first a local file on disk and then a remote URL. If either of these checks pass, the Provider is instantiated since the path does indeed represent a ManifestIndex.

func NewManifestProvider 

func NewManifestProvider(ctx context.Context, path string, mopts ...ManifestOption) (Provider, error)

NewManifestProvider accepts an input path which is checked against a local file on disk and a remote URL. If populating a Manifest struct is possible given the path, then this provider is able to return list of exactly 1 manifest.

func NewProvider 

func NewProvider(ctx context.Context, path string, mopts ...ManifestOption) (Provider, error)

NewProvider ultimately returns one of the supported manifest providers by attempting an ordered instantiation based on the input source. For the provider which does not return an error is indicator that it is supported and thus the return of NewProvider a compatible interface Provider able to gather information about the manifest.

func NewProviderFromString added in v0.2.0 

func NewProviderFromString(ctx context.Context, provider, path string, entity any, mopts ...ManifestOption) (Provider, error)

NewProviderFromString returns a provider based on a giving string which identifies the provider
