howto :

digitaloceanにデプロイ# 適宜取得% export DIGITALOCEAN_TOKEN=TEKITOUNATOKEN

# サーバー構築！% docker-machine create -d digitalocean \--digitalocean-access-token=$DIGITALOCEAN_TOKEN \--digitalocean-region "sgp1" \--digitalocean-size "1gb" my-awesome-app

# rails実験場が欲しければこれで% docker -it $(docker-machine config myapp) run rails bash% docker -it $(docker-machine config myapp) run rails c

# 終わったら削除% docker-machine rm myapp

docker-composeって？公式docker-tool 複数コンテナ同時実行yaml形式で構成定義マイクロサービスの実装形fig買収->docker-compose© CA Advance, Inc. All Rights Reserved 8

HOWTO : compose?　開発フロー» 1. docker-compose.ymlに構成を記載

» 2. %docker-compose build && docker-compose run

» 3. あとはサービスを使うだけ！

howto: docker-swarm1. トークン生成% docker-swarm create7988b7fb66edd9573eac62eefb87007f% export SWARM_TOKEN=7988b7fb66edd9573eac62eefb87007f

howto: docker-swarm2. docker-machineでマシン構築% docker-machine create -d digitalocean \--digitalocean-access-token=$DIGITALOCEAN_TOKEN --swarm --swarm-master \--swarm-discovery token://$SWARM_TOKEN swarm-master

% docker-machine create -d digitalocean \--digitalocean-access-token=$DIGITALOCEAN_TOKEN --swarm \--swarm-discovery token://$SWARM_TOKEN node01
