无法在Docker容器中调用nameko shell

Question

我正在调用示例服务的docker容器中的nameko shell，但收到了这个错误。我已经安装了两个容器。我的rabbitmq容器和我的服务容器。我正在从服务容器bash内部调用nameko shell。容器正确启动，服务容器成功连接。但是我不能用贝壳

错误

Answer 1

过了一会儿，我发现这是我自己的愚蠢错误。我忘了在我的nameko shell命令中添加配置文件。在执行nameko shell时，必须指定消息代理。在我的例子中，我需要运行nameko shell config config.yml。这使我能够连接并测试我的nameko服务
