Agile Web Development with Rails - Docker Image / Passenger Error (Pg 275)
Good morning @rubys .
I’m on Chapter 17 of the book. Just created the docker images and docker compose configurations.
But when I the containers, I’m receiving the following error:
depot-web-1 | [ E 2023-11-07 12:51:51.4166 48/Tr age/Cor/App/Implementation.cpp:221 ]: Could not spawn process for application /home/app/depot: The application encountered the following error: Permission denied @ rb_sysopen - /home/app/depot/config/master.key (Errno::EACCES)
Tried to change the permissions/owner of the file on the container, without success.
Someone is facing this problem?
root@2e8f3a4dee31:/home/app/depot/config# chmod -R 775 master.key
chmod: changing permissions of 'master.key': Read-only file system
Thanks
