docker exec在cron中不起作用 [英] docker exec is not working in cron

问题描述

我有一个非常简单的命令，可以作为命令或bash脚本独立运行，但是当我将其放入crontab时却不能

I have pretty simple command which is working fine standalone as a command or bash script but not when I put it in crontab

40 05 * * * bash /root/scripts/direct.sh >> /root/cron.log

具有以下一行

PATH=$PATH:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin
SHELL=/bin/sh PATH=/bin:/sbin:/usr/bin:/usr/sbin:/root/
# Mongo Backup
docker exec -it mongodb mongodump -d meteor -o /dump/

我试图将脚本的网址更改为/usr/bin/scirpts/没运气

I tried to change the url of script to /usr/bin/scirpts/ no luck

我什至试图直接在cron中运行脚本

I even tried to run script directly in cron

26 08 * * * docker exec -it mongodb mongodump -d meteor -o /dump/ >> /root/cron.log

没有运气，任何帮助表示赞赏.

with no luck, any help appreciated.

编辑

在/root/cron.log文件中也没有看到任何错误

I don't see any errors in /root/cron.log file either

推荐答案

您的docker exec命令说它需要伪终端并以交互模式运行"(

Your docker exec command says it needs "pseudo terminal and runs in interactive mode" (-it flags) while cron doesn't attach to any TTYs.

尝试将您的docker exec命令更改为此，看看是否可行?

Try changing your docker exec command to this and see if that works?

docker exec mongodb mongodump -d meteor -o /dump/
