虽然我可以登录运行容器甚至进入Asterisk控制台，如下所示，似乎也看不到该Asterisk服务的状态：

尝试与 一起运行exec，除此之外，这可能是事情容器是如何创建的？

每个使用 SystemD 控制服务的操作系统都会发生这种情况。 “systemctl”命令的作用并不多——它只是使用 d-bus 与 systemd 守护进程对话。但在 docker 容器内没有这样的东西。
使用以下命令覆盖 systemctl 时可以避免此错误 https://github.com/gdraheim/docker-systemctl-replacement直接执行服务的 ExecStart / ExceStop 部分，而不是要求 systemd 这样做。
