我正在尝试在一个容器节点和python中运行两项服务，但只有一个正在运行，我想在kubernetes的一个容器中运行两项服务。

我还尝试了节点的pm2服务。

您不打算采用什么方法来实现它。通常，docker容器应运行单个服务。结果，尽管没有可能，也可以使用包装脚本或supervisord之类的工具在docker中使用内置方法来使它正常工作，但是您可以在容器内管理多个服务-

或docs ：（我选择了supervisord选项，因为在我看来，它比包装脚本方式更干净，更易于管理）

使用流程管理器，例如supervisor。这是一个适度的需要您打包supervisord及其映像中的配置（或基于包含以下内容的映像进行配置）主管），以及它管理的不同应用程序。然后您将开始成为主管，该主管将为您管理流程。这是使用此方法的示例Dockerfile，假设预先编写的supervisord.conf，my_first_process和my_second_process 所有文件都与Dockerfile位于同一目录中。
FROM ubuntu:latest
RUN apt-get update && apt-get install -y supervisor
RUN mkdir -p /var/log/supervisor
COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
COPY my_first_process my_first_process
COPY my_second_process my_second_process
CMD ["/usr/bin/supervisord"]

https://docs.docker.com/config/containers/multi-service_container/

您在Dockerfile中当前使用的名称称为multisage build，到目前为止，不是您想要的。
