Rails doesn't see environment variable
Solution 1
export APP_NAME_DATABASE_PASSWORD=secretkey
is most likely scoping your environment variable to a bash process. Since Unicorn doesn't run as a child of bash process, it doesn't have access to this environment variable.
I'd recommend storing your ENV vars in a single place, such as application.yml
and loading them into your ruby environment at the start of your application. There are some great tools that do this. I'd recommend looking into Figaro: https://github.com/laserlemon/figaro.
Here's another post relevant to your question: Re-source .bashrc when restarting unicorn?
Solution 2
Try doing spring stop
followed by rails c
Spring is a rails application preloader that loads the ENV configuration. It might not have loaded the .bashrc
changes in your case.
Solution 3
I had a similar problem. A simple solution for you would be to run:
export RAILS_ENV=production && rails c
The reason is that when you do not use the export, the rails can not see the environment variable but you see its value when you execute echo
on the console.
Solution 4
Here is another option:
http://railsguides.net/how-to-define-environment-variables-in-rails/
Put your environment variables in local_env.yml
, and then put this in application.rb
config.before_configuration do
env_file = File.join(Rails.root, 'config', 'local_env.yml')
YAML.load(File.open(env_file)).each do |key, value|
ENV[key.to_s] = value.to_s
end if File.exists?(env_file)
end
Solution 5
For the ones using zsh:
echo 'export APP_NAME_DATABASE_PASSWORD=value' >> ~/.zshenv
source ~/.zshenv
Check if it has really been set using:
echo $APP_NAME_DATABASE_PASSWORD # value
For running rails applications you might also want to do spring stop
.

I am trying to move a Rails application into production but I am having a problem with Rails not seeing my environment variable.
I have the password for my database setup in my .bashrc file like
export APP_NAME_DATABASE_PASSWORD=secretkey
In irb
ENV["APP_NAME_DATABASE_PASSWORD"]
returns
secretkey
.Using
RAILS_ENV=production rails c
and just
rails c
returns
secretkey
but when starting the application I getAccess is denied (using password: NO)
I am using a slightly modified version of the init script on "How To Deploy a Rails App with Unicorn and Nginx on Ubuntu 14.04" to start unicorn.
It is being hosted on Ubuntu Server 14.04.

agustaf about 8 yearsIs there any way to put those variables in Unicorns scope? Or is that a bad Idea?
-
Anthony E about 8 yearsYes, you can set them directly in the script that starts unicorn, or in the
unicorn.conf
file. However, one disadvantage of this approach, however, is that your ENV variables won't be accessible forrake
and the rails console. -
amalrik maia about 8 yearsI think Anthony explanation is probably right. But i think storing ENV vars in an yml file is not good. If you do that sensitive information could be committed to SCM, which could be an opening to vulnerabilities. Please take a look at dotenv gem i think it is what youre looking for.

Anthony E about 8 yearsYeah don't commit application.yml! same goes for dotenv.
