Cron Job with Whenever Gem, не работает в амазонке эластичный beanstalk

Question

Я установил жемчужину: всякий раз, когда-эластичный мешок, но я не могу установить его правильно, что не так?

Ошибки:

Некоторые подсказки для этой проблемы? Что означает константа $ EB_CONFIG_APP_USER, когда я ее определяю?

Answer 1

Какую версию Усиливающего бобового AMI вы используете? Начиная с 2014.09, старые переменные среды (например, $ EB_CONFIG_APP_USER) не работают. См. ПРЕДУПРЕЖДЕНИЕ в верхней части всякий раз, когда-elasticbeanstalk readme и это драгоценный камень Issue 18.

Они могут обновлять всякий раз, когда используется эластичный жемчуг, для обработки нового подхода к изменению среды, но тем временем вы, вероятно, застряли в использовании по умолчанию whenever gem и записываете свой собственный код для вызова whenever --update. Мой every-cron.config выглядит так. Обратите внимание, что он не обрабатывает опцию «только лидера».
