Where are you finding this path /opt/elasticbeanstalk/srv
Its not in any beanstalk i have seen.
Thoughts?

same here, I can't find /opt/elasticbeanstalk/srv path anywhere.

would it be possible to make many sites this way on a single instance? eg: http://admin.myapp.com and http://frontend.myapp.com/ I need the frontendapp to pull resources from the admin app. Each are separately managed repos. I haven't found how I could deploy two apps code bases to one single instance. Any thoughts would be appreciated.

Could not find /opt/elasticbeanstalk/srv path too
