Question

我写了一个bash脚本来最后构建一个docker容器（一个NODE JS应用程序），以便该应用程序在DEV服务器上运行。问题是bash脚本必须在多个服务器上分阶段运行，即，我们需要在本地构建docker容器，将ssh到跳转框并在其中进行rsync，然后将其从Jumpbox同步到dev服务器，然后再次使用它（如果手动完成此过程）。

如果您在下面的BASH脚本中查看第5步，则rsync会完成，并且脚本会运行到SSH到Jumpbox服务器，但是，脚本在那里停止了，我刚刚登录到Jumpbox。

有人可以让我知道此bash脚本出了什么问题，我该如何解决？

谢谢。

最好， R

一旦您向另一个框打开ssh会话，您的本地脚本就会停止，因为它正在等待ssh会话结束。您只是坐在远程框中的命令提示符下。

看起来您打算发生的是ssh之后的命令在远程机器上运行。要将命令发送到远程计算机，请重定向它们：

ssh ${enumber}@10.188.129.25 <<'ENDSSH'
# series of commands to 
# run on remote host
ENDSSH

考虑通过Shellcheck运行脚本-除了您要的脚本之外，您还有其他问题。
