#事前準備
*　git
*　VirtualBox
*　vagrant
はインストールしておく
gitはGitBashを使えるようにするとWindowsでもsshできるので便利

#CoreOSの準備
##イメージの取得

GitBash

git clone https://github.com/coreos/coreos-vagrant/

##Vagrantfileの編集
CoreOSをHostOSと同一ネットワーク上に配置
80ポートのポートフォワーディングも設定

Vagrantfile

#line:121 config.vm.network :private_network, ip: ip
line:122 config.vm.network :public_network, bridge: \'en0: Ethernet\', type: "dhcp"
#line:123 config.vm.network :forwarded_port, guest: 80, host: 3000

#CoreOSの起動

GitBash

cd coreos-vagrant
vagrant up

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

systemctl start [e-mail]

Stdout from the command:



Stderr from the command:

Job for [e-mail] failed because a configur
ed resource limit was exceeded. See "systemctl status system-cloudinit@-var-tmp-
hostname.yml.service" and "journalctl -xe" for details.

##起動確認

GitBash

vagrant status

Current machine states:
core-01                   running (virtualbox)

#docker-composeをインストールする
##CoreOSにsshでログインする

GitBash

vagrant ssh

または、Rlogonなどでsshする。addressやusernameはCoreOS起動時に出力されたものを利用する
private-keyは~/.vagrant.d/insecure_private_key
##docker-composeをインストールする
docker-composeのリリースノートにあるコマンドを参考に

Rlogon

curl -L https://github.com/docker/compose/releases/download/1.3.0rc3/docker-compose-`uname -s`-`uname -m` > ~/docker-compose
chmod +x docker-compose
./docker-compose --version

docker-compose version: 1.3.0rc3
CPython version: 2.7.9
OpenSSL version: OpenSSL 1.0.1e 11 Feb 2013

#docker-compose用の設定ファイルを作成

Rlogon

vi docker-compose.yml

docker-compose.yml

#Docker起動

Rlogon

./docker-compose up -d

##起動確認

CoreOS上から起動確認

wget http://127.0.0.1/ --no-proxy

あとはブラウザで起動確認
