CronJob is failing inside the container while using docker-desktop in windows 10

I am working on a application where I am running multiple containers using docker-compose.yml. All the containers are successfully up. One of the container is having a cron file with the following contents:

* * * * * sshpass -p root ssh -o StrictHostKeyChecking=no root@myserver"./script.sh" > /proc/1/fd/1 2> /proc/1/fd/2

whenever this cron job is trying to run I am getting the below error in intelliJ console:

cron_1                                  | crond: USER root pid  35 cmd sshpass -p root ssh -o StrictHostKeyChecking=no root@myserver"./script.sh" > /proc/1/fd
/1 2> /proc/1/fd/2
: nonexistent directory                 | /bin/sh: can't create /proc/1/fd/2

When I logged in container cli, I can see that directory location exists:- Container File location

It's wokring fine on ubuntu but not on windows.

below is the output of docker version

Solution

  • Make sure line endings in your cron file set to Linux/UNIX
