Overriding ENV variables set in circle.yml

Build Environment
1

HI All,

I’m currently using circle yml to define environment variables like so:

machine:
  environment:
    RAILS_ENV=test

This works great, but for one of my three containers, I want to over-ride this to RAILS_ENV=production.

In the script I’m using for each container I’ve tried to override using:

export RAILS_ENV=production
RAILS_ENV=production bundle exec rails s

Using both of these did not seem to work. The rails server is still in test mode. Any ideas how I can resolve this?

If you want to set an env for just one step, try setting it using the modifier https://circleci.com/docs/configuration/#modifiers
