Functions

func BuildEnvVar

func BuildEnvVar(keychain authn.Keychain, images ...string) (string, error)

BuildEnvVar creates the contents to use for authentication environment variable.

Complementary to `ReadEnvVar`.

func NewKeychain

func NewKeychain(envVar string) authn.Keychain

NewKeychain returns either a EnvKeychain or a authn.DefaultKeychain depending on whether the provided environment variable is set

func ReadEnvVar

func ReadEnvVar(envVar string) (map[string]string, error)

ReadEnvVar parses an environment variable to produce a map of 'registry url' to 'authorization header'.

Complementary to `BuildEnvVar`.

Example Output:

gcr.io -> Bearer asdf=
docker.io -> Basic qwerty=

func ReferenceForRepoName

Types

type EnvKeychain

type EnvKeychain struct {
	EnvVar string
}
