docker: Network timed out...
Docker for macで初めてDockerに触ってみたが
$ docker run hello-world
すると
Unable to find image 'hello-world:latest' locally Pulling repository docker.io/library/hello-world docker: Network timed out while trying to connect to https://index.docker.io/v1/repositories/library/hello-world/images. You may want to check your internet connection or if you are behind a proxy.. See 'docker run --help'.
てな具合で、先に進めない。
ぐぐると
$ docker-machine restart default $ eval $(docker-machine env default)
Host does not exist: "default"
となる。
そもそもdefaultと言うものがない。
defaultについてさらにぐぐると
$ docker-machine create -d virtualbox default
という記述を見つける
（自分のMacにはvirtualboxはすでにInstall済み。だが、Installしているvirtualboxのことなのだろうか？）

なんか出来てるし、Virtualboxにもなんか出来てる。
これがDockerコンテナを動かすホストなのかな？
$ docker-machine restart default Restarting "default"... (default) Check network to re-create if needed... (default) Waiting for an IP... Waiting for SSH to be available... Detecting the provisioner... Restarted machines may have new IP addresses. You may need to re-run the `docker-machine env` command.
ぉぉぉーすすんだ！

This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: https://cloud.docker.com/ For more examples and ideas, visit: https://docs.docker.com/engine/userguide/

入ったらしいがどうすればいいんだろう？
サンプルではhttp://localhost/にアクセスしろって言ってるけど、だめだった
$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default - virtualbox Running tcp://192.168.99.100:2376 v1.12.6
このIPかな？ってことで
http://192.168.99.100
にアクセスしたら
やったー！
