Docker and cron environments












-1















I have problem with environment variables in docker image..
I created file: /cron.sh



#!/bin/bash

whoami
export


When I run manual in console: sh /cron.sh is OK (root, full envs) but when I add command to cron that I getting: root, basic envs (not have my variables).



Crontab -e:



* * * * *  /bin/bash /cron.sh > /proc/$(cat /var/run/crond.pid)/fd/1 2>&1


Why are the differences?

  • How are you setting up your container? What does your Dockerfile look like?

  • You should really add that information to the question. Also, the Dockerfile you've shown has neither a CMD or ENTRYPOINT. How are you starting cron?

before run "exec crond -n" in entrypoint I save environments to file.
