Rails, NGINX, Unicorn and Capistrano: Missing `secret_token`

I have deployed my Rails 4.2.0 app into a Ubuntu 14.04 VPS using NGINX, Unicorn and Capistrano. Everything works fine except by the missing of my secret_key_base in production environment.

Here is my secrets.yml production block:

production:
  secret_key_base: <%= ENV["APP1_SECRET_KEY_BASE"] %>

In my ~/.bashrc in the server I have:

export APP1_SECRET_KEY_BASE=token

It's all ok with the variable:

deployer@euler:~$ echo $APP1_SECRET_KEY_BASE
token

deployer@euler:~$ irb
2.2.0 :001 > ENV["APP1_SECRET_KEY_BASE"]
 => "token"
2.2.0 :002 > exit

But when I try to access my app I get the error in the log/unicorn.log:

ERROR -- : app error: Missing `secret_token` and `secret_key_base` for 'production' environment, set these values in `config/secrets.yml` (RuntimeError)

Seems to me that the Unicorn cannot access those values. So I have tried to use the NGINX Env functionality, but again no success, tried both ways in my nginx.conf:

env APP1_SECRET_KEY_BASE;

and

env APP1_SECRET_KEY_BASE=token;

But again, no success. The configuration passes the nginx start but the app doesn't work.

I even tried to use the dotenv gem, but no success also.

Any tip of what may be happening?

In /etc/nginx/nginx.conf

add the variables you need using:

passenger_env_var VARIABLE_NAME "value";

You can use the dotenv-rails gem to accomplish this. Have a file in your shared directory on your server called .env and copy it into the current directory on deploy.

That file would have some content like this:

SECRET_KEY_BASE=6c073f07...

The other benefit of using dotenv-rails is that if your application requires any other environment configuration you now will have a place for it.
