Docker and cron environments
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?
bash docker cron centos

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?

I have solution..
before run "exec crond -n" in entrypoint I save environments to file.
export > /.env
Next in cron add:
* * * * * source /.env; /bin/bash /cron.sh > /proc/$(cat /var/run/crond.pid)/fd/1 2>&1
I hope I helped :-)
