This protocol is heavily inspired by Git, but it differs in the information shared. Credential helper protocolĬredential helpers can be any program or script that follows a very simple protocol. password) in base64 encoding in the config filesĭescribed above. If none of these binaries are present, it A specialĬase is that on Linux, Docker will fall back to the “secretservice” binary if “osxkeychain” on macOS, “wincred” on windows, and “pass” on Linux. Default behaviorīy default, Docker looks for the native binary on each of the platforms, i.e. The credentials from the file and run docker login again.

With a specific keychain or external store.

To use a credentials store, you need an external helper program to interact Is more secure than storing credentials in the Docker configuration file. Such as the native keychain of the operating system. The Docker Engine can keep user credentials in an external credentials store, Windows, via the procedure described below. $HOME/.docker/config.json on Linux or %USERPROFILE%/.docker/config.json on When you log in, the command stores credentials in You can log into any public or private repository for which you haveĬredentials.
