Bash 使用云构建在GCE实例上重新启动服务

我有一个GCE实例，我使用云构建将代码推送到它。我需要在推送代码后重新启动该VM上的服务。以下是我的云构建YAML的外观：

steps:

- name: 'gcr.io/cloud-builders/gcloud'
  entrypoint: 'bash'
  args: 
  - '-c'
  -  |
      for d in *; do
              gcloud compute scp $d user@instance-1:/path/to/directory --zone=asia-south1-a --recurse

      done

- name: 'gcr.io/cloud-builders/gcloud'
  entrypoint: 'bash'
  args:
  - '-c'
  -  |
      gcloud compute ssh user@instance-1 --zone=asia-south1-a --command="service uwsgi restart"

timeout: 1200s

虽然第一步工作正常，但在尝试重新启动服务时，我收到以下错误：

我尝试过禁用上面提到的交互式身份验证机制，但没有成功。请提供帮助。

在调查此问题之后，我建议一种解决方法，即让侦听器以root用户身份运行，以检查文件是否存在。例如，当存在使用touch的构建时，该文件由用户从Cloud Build创建。如果文件存在，侦听器将删除该文件并重新启动服务。守则：

#!/bin/bash

# Listener to be run by root. When user from
# Cloud Build touches $FILE, root removes it
# and restarts the service from within the VM.

FILE="/home/user/file"

function listen()
{
        if [ -f "$FILE" ]; then
            rm $FILE
            service uwsgi restart
            sleep 60
        else
            sleep 10
        fi
}

while true
do
    listen
done

试着用这里描述的sudo来运行它。一个能解决你的问题吗？@guillaumeblaquiere，我不这么认为。重置还会导致相当大的停机时间，这是无法承受的。请同意，VM重新启动和停机时间更长。根据您的限制，这可能是一个解决方案。但不是！
