gcloud 命令在 crontab -e 中不起作用？
gcloud commands not working in crontab -e?
我的 google 云项目中几乎没有项目 运行，我正试图在特定时间停止它们并在特定时间开始。
我创建了一个用于停止的脚本文件test.sh
#!/bin/bash
gcloud compute instances stop instance1
现在我尝试 crontab -e 并添加了这个，
30 01 1-31 1-12 1-5 /home/user/test.sh >> /var/log/test.log
但这并没有停止我的 gcp 实例，也没有创建任何日志文件。
更新，
我只是对时间安排感到困惑
00 10 * * 1-5 start.sh
00 01 * * 1-5 stop.sh
00 01 * * 6 stop.sh
这在周六和周日如何运作？我想在星期六 1am 停止实例并在星期一 10am 重新启动它。我的配置正确吗？
从周一到周五，它应该在凌晨 1 点关闭并在早上 10 点开始。
`crontab` 运行s 作为 root (!?)，因此未针对 `gcloud` 进行身份验证
可能有更好的选择，但作为解决方案的概述：
- 创建一个具有适当权限的服务帐户，供
cron 使用
- 在实例上为 root 激活服务帐户
gcloud auth activate-service-account（在启动期间或每个 cron 任务）
- 运行
cron 个职位

抱歉，我误读了你的问题并认为你也想 运行 cron 在 Compute Engine 实例上。
我想你想 运行 cron 本地。
诀窍 (!) 是确保您的命令使用绝对路径。
which gcloud
对我来说，这个 returns /snap/bin/gcloud 因为我正在 运行 宁 Ubuntu 并快速安装了 gcloud。这对您来说可能会有所不同。
那么，以下对我有用：
stop.sh:
#!/usr/bin/env bash
PROJECT=[[YOUR-PROJECT]]
INSTANCE=[[YOUR-INSTANCE]]
ZONE=[[YOUR-ZONE]]
echo "[$(date --rfc-3339=seconds)] Stopping ${INSTANCE}"
/snap/bin/gcloud compute instances stop ${INSTANCE} \
--project=${PROJECT} \
--zone=${ZONE} \
--verbosity=debug
echo "[$(date --rfc-3339=seconds)] Stopped ${INSTANCE}"
NOTE I've added --verbosity=debug but you may prefer to reduce or omit this entirely.
确保脚本可执行：
chmod +x /path/to/stop.sh
然后crontab -e:
# Whosebug: 64994379
* * * * * /path/to/stop.sh >>/path/to/stop.log 2>&1
NOTE You want 30 01 1-31 1-12 1-5 here. This may be simpler as 30 01 * * 1-5

Google Cloud Scheduler 为您提供 运行ning 的额外好处，无论您的主机 (运行ning cron) 是否 运行宁.
如果您想非常勤奋，您可以扩充脚本以遍历所有项目并关闭每个实例。在这种情况下，最好让脚本也通知您它的成功或失败，以免您沾沾自喜。
我建议遵循有关
的官方文档
