linux – 在Alpine Docker容器中运行OpenSSH

我已经 installed OpenSSH了,现在我希望通过运行/etc/init.d/sshd start来运行它,如 documentation所述.但是它没有开始：

/ # /etc/init.d/sshd start
 /bin/ash: /etc/init.d/sshd: not found

思考？

附：

/ # ls -la /etc/init.d/sshd 
-rwxr-xr-x    1 root     root          2622 Jan 14 20:48 /etc/init.d/sshd

解决方法

容器不是完整安装的环境.
官方文件是针对某些机器安装的高山.
开启,启动服务等容器没有的服务.

因此,/ etc / init.d /中的任何内容都不能直接用在启动服务使用的容器中(如systemd或alpine的rc *).这就是为什么你得到错误消息导致rc *没有安装在容器中.

你需要做的是开始sshd manuanlly.
你可以看看下面的例子：
