Help me to solve it. Thanks in advance.

Answer 1

To run sidekiq you need a redis server:
Redis provides data storage for Sidekiq. It holds all the job data along with runtime and historical data to power Sidekiq's Web UI.
From the documentation:
https://github.com/mperham/sidekiq/wiki/The-Basics#redis
https://github.com/mperham/sidekiq/wiki/Using-Redis
If your redis server runs anywhere else than localhost:6379, you can configure the URL.
To setup a local redis server, you can install it with homebrew:
brew install redis
redis-server # will run the server on `localhost:6379`
Then in a second shell window, try to launch sidekiq:
bundle exec sidekiq

Answer 2

You set sidekiq to use redis at redis://redis:6379/0, but that's not a valid url on your system. In particular, host redis can't be resolved to an IP address.
