雖然我可以登入運行容器甚至進入Asterisk控制台，如下所示，似乎也看不到該Asterisk服務的狀態：

嘗試與 一起運行exec，除此之外，這可能是事容器是如何建立的？

每個使用 SystemD 控制服務的作業系統都會發生這種情況。 「systemctl」指令的作用並不多－它只是使用 d-bus 與 systemd 守護程式對話。但在 docker 容器內沒有這樣的東西。
使用以下命令覆蓋 systemctl 時可以避免此錯誤 https://github.com/gdraheim/docker-systemctl-replacement直接執行服務的 ExecStart / ExceStop 部分，而不是要求 systemd 這樣做。
