Sidekiq + redis + docker-compose + rails

I configured my project to work with the listed technologies, but when requesting the route http://localhost: 3000/sidekiq, it gives the error Error connecting to Redis on 127.0.0.1:6379 (Errno :: ECONNREFUSED). In the terminal where docker is running, you can see the following:

Please tell me if I missed some configuration file or where I am wrong with the settings?
