@tobsn I'm sorry but it's been a year and a half since I last used Elastic Beanstalk so I don't know if it's still valid. I do know that I used this in combination with other config files making use of container_commands though, so I have no reason to believe it wouldn't still work.

@henhal yeah it somehow started working... must have been the mode settings, idk... :D
