Docker Swarm Init でエラーメッセージが出る

$ docker swarm init

Error response from daemon: could not choose an IP address to advertise since this system has multiple addresses on different interfaces (10.0.2.15 on eth0 and 192.168.99.100 on eth1) - specify one with --advertise-addr

複数IPアドレスを持っているのが問題っぽいので、 たぶん、IPを指定する必要がある？ (Oracle VirtualBoxをインストールしてるので、複数のIPアドレスを持っている)

$ docker swarm init --advertise-addr="192.168.99.100"
