У меня есть работающее приложение Rails в Google Cloud Run, использующее:
- Cloud Build
- Cloud Registry
- Cloud Run
- Cloud SQL
- Облачное хранилище
- Облачная служба управления ключами
- Облачный планировщик
Я настроил Sidekiq для выполнения некоторых заданий в фоновом режиме, но Я получаю эту ошибку в журналах Cloud Run, когда пытаюсь выполнить задания Sidekiq.
Redis::CannotConnectError (Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)):
Я предоставил вам здесь мои настройки развертывания:
