I've tried different configurations, I've checked other builds, but the problem still persists, So far, Sidekiq runs well outside of Docker.
我尝试了不同的配置，我检查了其他版本，但问题仍然存在，到目前为止，Sidekiq 在 Docker 之外运行良好。

Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)
Your app tries to connect on the localhost interface of the container it is running in, but redis is running in a different container.
您的应用程序尝试在它运行的容器的 localhost 接口上进行连接，但 redis 正在另一个容器中运行。
Modify your app config to use the link name of the redis container (redisin your case) as hostname for the connection.
修改您的应用程序配置以使用 redis 容器的链接名称（redis在您的情况下）作为连接的主机名。

Check if your redis server is running, start redis by using the following command in the terminal:
检查您的 redis 服务器是否正在运行，在终端中使用以下命令启动 redis：
redis-server
回答by Ajay
Just start your redis server by using redis-servercommand. After start sidekiq
只需使用redis-server命令启动你的 redis 服务器。启动 sidekiq 后
回答by Abhiyan Timilsina
If you are using heroku and having such problem then you need to specify REDIS_PROVIDER_URL in your env
如果您正在使用 heroku 并遇到此类问题，那么您需要在您的环境中指定 REDIS_PROVIDER_URL
