cf. herokuでsinatraアプリをデプロイしてみた
順を追ってやってみる。
ログインと公開鍵の登録
Heroku Toolbelt のインストールは終わっているので、キーの登録から。
^o^ > heroku login Enter your Heroku credentials. Email: [email protected] Password (typing will be hidden): Could not find an existing public key. Would you like to generate one? [Yn] Y Generating new SSH public key. Uploading SSH public key C:/Users/hiro/.ssh/id_rsa.pub... done Authentication successful.
ログインしようとすると public key がない、作るか？といわれるので、Y と答える。これでキーができたはず。
もう一回ログイン。
^o^ > heroku login Enter your Heroku credentials. Email: [email protected] Password (typing will be hidden): Authentication successful.
今度はログインできた。じゃ次、public key（公開鍵）の登録。
^o^ > heroku keys:add Found existing public key: C:/Users/takatoh/.ssh/id_rsa.pub Uploading SSH public key C:/Users/takatoh/.ssh/id_rsa.pub... done
よし、OK。
簡単なSinatraアプリを作る
チョー簡単な、Hello, Heroku と表示するだけのアプリ。
Gemfile:
source "https://rubygems.org" gem "sinatra"
Procfile:
web: bundle exec rackup config.ru -p $PORT
sample.rb:
require 'bundler/setup'
require 'sinatra/base'
class Sample < Sinatra::Base
get "/" do
"Hello, Heroku."
end
end
config.ru:
$:.unshift(File.dirname(__FILE__)) require 'sample' run Sample
.gitignore:
.bundle
まずはこれだけを Git のリポジトリに commit する。
^o^ > git init Initialized empty Git repository in C:/Users/takatoh/Documents/w/takatoh-sample/ .git/ ^o^ > git add . ^o^ > git commit -m "First commit." [master (root-commit) fa02bb8] First commit. 5 files changed, 19 insertions(+) create mode 100644 .gitignore create mode 100644 Gemfile create mode 100644 Procfile create mode 100644 config.ru create mode 100644 sample.rb
ローカルで試してみる
^o^ > foreman start 'foreman' は、内部コマンドまたは外部コマンド、 操作可能なプログラムまたはバッチ ファイルとして認識されていません。
あれ、ダメじゃん。foreman とやらはインストールされてないのかな。まあいいや。
デプロイしてみる
^o^ > heroku create Creating limitless-sea-3233... done, stack is cedar http://limitless-sea-3233.herokuapp.com/ | [email protected]:limitless-sea-3233.git Git remote heroku added ^o^ > git remote -v heroku [email protected]:limitless-sea-3233.git (fetch) heroku [email protected]:limitless-sea-3233.git (push)
heroku create にアプリ名を与えないと適当な名前がつくらしい。上では limitless-sea-3233 ってのがそう。git のリモートリポジトリに heroku が追加されてるのがわかる。
それじゃ、Heroku にデプロイしてみよう。
^o^ > git push -u heroku master Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
あれ、だめだ。なんでだ。
しばらく考えて、ログを見て気がついた。さっき登録したキーは C:/Users/takatoh/.ssh/ に保存されている。けど、普段 git でつかっているキーは C:\Users\takatoh\Documents\.ssh にある。これじゃないかと思って、（バックアップを作ったうえで）上書きしてみた。今度はどうかな。
^o^ > git push -u heroku master Initializing repository, done. Counting objects: 7, done. Delta compression using up to 2 threads. Compressing objects: 100% (4/4), done.

まだだめだ。今度はなんだ。どうやら Gemfile.lock が必要で、チェックインしろといっている。
^o^ > git status

(use "git add ..." to include in what will be committed)
Gemfile.lock

さあ、今度はどうだ。
