func NewCredentialFunc ¶

func NewCredentialFunc() (auth.CredentialFunc, error)

NewCredentialFunc returns an auth.CredentialFunc backed by a credential resolution chain that checks Docker and Podman auth locations. The resolution order is:

1. Docker: via NewStoreFromDocker (handles $DOCKER_CONFIG and $HOME/.docker/config.json)
2. Podman runtime: $XDG_RUNTIME_DIR/containers/auth.json
3. Podman config: $HOME/.config/containers/auth.json

Podman paths that do not exist are silently skipped.

func NewRepository ¶

func NewRepository(ref string, credFunc auth.CredentialFunc, plainHTTP bool) (*remote.Repository, error)

NewRepository creates an authenticated remote.Repository from a full OCI reference. The plainHTTP parameter forces HTTP instead of HTTPS, or is auto-detected from http:// scheme.

func ParseTag ¶

func ParseTag(ref string) string

ParseTag extracts the tag or digest from an OCI reference. Returns "latest" if no tag or digest is present.
