我尝试运行sidekiq worker和Rails。当我尝试docker-compose up worker时，我得到以下错误：

我已经尝试了不同的配置，我已经检查了其他版本，但问题仍然存在，到目前为止，Sidekiq运行良好以外的Docker。

Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)

您的应用尝试连接到运行它的容器的localhost接口，但是redis正在不同的容器中运行。
修改你的应用配置，使用redis容器的链接名（在你的例子中是redis）作为连接的主机名。

在macOS上（使用Homebrew），我可以通过运行以下命令修复此问题：

brew services start redis

如果您还没有安装redis，您需要先运行以下命令：

brew install redis

Redis快速回顾

有一个类似的问题，在我的情况下，我有一个脚本，启动redis和其他初始设置，我忘了运行它。它通常与CaS（Tomcat）中断，但这一次它打破了由于redis，我几乎忘记了这是由脚本设置。
无论如何，为了补充其他答案，检查是否存在问题的快速方法是运行

redis-cli

它会让你知道redis是否在工作，从而帮助你记住是否需要运行它。
如果Redi没有运行，你会得到一个redis控制台：

redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
not connected>

如果它正在运行，您将得到一个redis控制台（在交互模式下），请参见documentation：

redis-cli
127.0.0.1:6379>

例如你可以说：PING，它将返回PONG

redis-cli
127.0.0.1:6379> PING
PONG

要运行Redis服务器，请执行以下操作：

redis-server

如果您正在使用heroku并遇到此类问题，则需要在环境中指定REDIS_PROVIDER_URL
