Hi, I would like to install Openproject within my server. I have followed docker installation guide, but it was not work. I tried using this command for testing first:

docker run -it -p 8080:80 -e SECRET_KEY_BASE=secret openproject/community:5.0

it said that postfix is exit.

And also I ran this command to check it

docker exec -it CONTAINER_ID bash -c "cat /var/log/supervisor/*.log

it said that phusion passenger is error.

And I would like to know how to get SECRET_KEY_BASE

Thanks
