        Make the Podman and Docker compatibility API available over the network
        with TLS client certificate authentication.

        This allows Docker clients to connect with the equivalents of the Docker
        CLI `-H` and `--tls*` family of options.

        For certificate setup, see https://docs.docker.com/engine/security/protect-access/

        This option is independent of [](#opt-virtualisation.podman.dockerSocket.enable).
