Answer 1

This is a known issue on OSX due to incompatibilities between bsdtar (that ships with OSX) and gnutar (what docker is expecting).

It can be fixed simply by ensuring that gnutar is available on the path as "tar". In OSX, this can be accomplished with

brew install gnu-tar --with-default-names

Answer 2

To add a little more explanation to the answer from @Gregory Haskins,

--with-default-names option is unavailable now.

Instead, add gnu-tar location to PATH so that gnu-tar is found and runs before bsdtar(of macOS).

This can be accomplished with

export PATH="/usr/local/opt/gnu-tar/libexec/gnubin:$PATH"
