Question

I want to host my rails website on Amazon Elestic Beanstalk. I followed this guide : http://docs.amazonwebservices.com/elasticbeanstalk/latest/dg/create_deploy_Ruby_rails.html.

Now, I have this error : Ruby (Rack) application could not be started

Error message:

Nothing one the trace in on my source code. I didn't found anything on the Internet. You can find the source code of the application here : https://github.com/GCorbel/comment-my-projects.

I was experiencing that, and found out that this isn't related with rake itself. That's happening probably because one of your gems isn't getting installed. In my case, it was pg that wasn't getting installed since it needs the pg_config executable.

So, in my case, to fix that, I added the following sections to .ebextensions/default.config:

packages:
  yum:
    git: []
    postgresql-devel: []

# Run rake tasks before an application deployment
container_commands:
  01bundler-pg:
    command: bundle config build.pg --with-pg-config=/usr/bin/pg_config

Even if you don't use pg, check if any of your gems needs development headers or executable files installed.
