"Deploy to Heroku" Buttonで環境変数を設定する/させる

More than 5 years have passed since last update.

Heroku Buttonでデプロイするときに、環境変数を設定してイニシャライズしたい場合ありますね。

app.json
{
  /* 続きから */
  "env": {
    "URL": "https://github.com/teki/tou",
    "SECRET_TOKEN": {
      "description": "A secret key.",
      "generator": "secret"
    },
    "CONCURRENCY": {
      "description": "The number of processes to run.",
      "value": "5"
    }
  }
}
  • 直接値を指定する
  • "description"で説明をつける
  • "generator": "secret"でランダムな文字列を自動生成できる
  • "value"で初期値を設定できる
  • "required"で必須設定(デフォルトでon)

Heroku Buttonを押すとこういう感じ
