Functions

func Keychain 

func Keychain(keychainOpts auth.KeychainOpts, environFunc func() []string) (regauthn.Keychain, error)

Keychain implements an authn.Keychain interface by composing multiple keychains. It enforces an order, where the keychains that contain credentials for a specific target take precedence over keychains that contain credentials for 'any' target. i.e. env keychain takes precedence over the custom keychain. Since env keychain contains credentials per HOSTNAME, and custom keychain doesn't.
