调用SSH时Shell脚本停止

Question

我试图用一个脚本在AWS上自动化一些事情。

1. 登录并关闭停靠器--然后删除所有图像
2. 将本地文件复制到服务器
3. 登录并启动

我的剧本是

#log in and shut down docker-compose then remove all images
ssh -i "~/Documents/AWS-Keys/mykey.pem" ubuntu@XX.XXX.XX.XXX
docker-compose down
docker image prune -f
exit

#copy local files to server
scp -r -i "~/Documents/AWS-Keys/mykey.pem" ./ubuntu ubuntu@XX.XXX.XX.XXX:/home

#log in and start docker-compose
ssh -i "~/Documents/AWS-Keys/mykey.pem" ubuntu@XX.XXX.XX.XXX
docker-compose up -d
exit

我也尝试过logout而不是exit，同样的结果。

正在运行

$ ./upload.sh 

产出如下：

在得到一些反馈后，我也尝试了

ssh -i "~/Documents/AWS-Keys/mykey.pem" ubuntu@XX.XXX.XX.XXX
docker-compose down;
docker image prune -f;
exit

同样的结果。

我的理解是，您希望在服务器上运行命令，在这种情况下，只需在ssh之后编写它：

ssh -i "~/Documents/AWS-Keys/mykey.pem" ubuntu@XX.XXX.XX.XXX "docker-compose down ;docker image prune -f"

您可以通过HEREDOC发送更长的脚本

ssh -i "~/Documents/AWS-Keys/mykey.pem" ubuntu@XX.XXX.XX.XXX  <<COMMANDS
docker-compose down
docker image prune -f
