Question

This is my config.yml file. In fact user_id, api_key and shared_secret are the same for each environment (development, test or production).

development:
  user_id: '1234'
  api_key: '1234'
  shared_secret: '43243'
  some_dev_data: 'fdsfdsfd'
test:
   some_test_data: 'rytr'

production:
   some_prod_data: 'hgf'

How do I make them independent from current environment? Or how to share them between all environments?

Answer 1

You can use anchors to pull out shared data:

shared_stuff: &shared
  user_id: '1234'
  api_key: '1234'
  shared_secret: '43243'

development:
  <<: *shared
  some_dev_data: 'fdsfdsfd'

test:
  <<: *shared
  some_test_data: 'rytr'

production:
  <<: *shared
  some_prod_data: 'hgf'

Your values under shared_stuff are given the anchor name shared which you can then pull into your different environments.
