hubot-slackをHerokuで動かせる方法

hubot-slack

$ npm i -g hubot hubot-slack yo generator-hubot coffee-script
$ mkdir -p /path/to/hubot
$ cd /path/to/hellobot
$ yo hellobot
$ npm i hubot-slack -S
$ vim Procfile
web: bin/hubot --adapter slack
$ ./bin/hubot

あとは、これをHerokuにpushすればいいのですが、Freeで使うためには、幾つかの工夫が必要になります。

# heroku create
$ heroku login
$ heroku create
$ heroku git:remote -a ${appname}

# 念のためスケールなどを最小にする
$ heroku ps:scale web=1
$ heroku addons:add redistogo:nano
$ heroku config:set HUBOT_SLACK_TOKEN=xoxb-000000000-XXXXXXXXXXXXX

# process-schedulerアドオンの追加
# https://devcenter.heroku.com/articles/process-scheduler
$ heroku addons:add process-scheduler
$ heroku addons:open process-scheduler
# 範囲指定して0を入力するのですが、"1:00-6:00"で良いと思います。0の時間を寝かせます

# keepaliveをインストール
$ npm i hubot-heroku-keepalive -S
$ vim ./external-scripts.json
[ "hubot-heroku-keepalive" ]

# keepaliveの設定
# https://devcenter.heroku.com/articles/scheduler
$ heroku config:add HUBOT_HEROKU_WAKEUP_TIME=8:00
$ heroku config:add HUBOT_HEROKU_SLEEP_TIME=24:00
$ heroku config:add TZ='Asia/Tokyo'
$ heroku config:set HUBOT_HEROKU_KEEPALIVE_URL=$(heroku apps:info -s | grep web-url | cut -d= -f2)
$ heroku addons:create scheduler:standard
$ heroku addons:open scheduler
# 以下を追加します
# curl ${HUBOT_HEROKU_KEEPALIVE_URL}heroku/keepalive

# heroku push
$ git add -A
$ git push heroku master

プラグインの追加

基本的には、npm i ${plugin} -Sした後に、ファイルを編集します。

external-scripts.json

[
  "hubot-heroku-keepalive",
  "hubot-shipit",
  "${plugin}"
]
