Rails: How to fix “Missing secret_key_base for 'production' environment”

Question

I simply can\'t get past the message:

Missing `secret_key_base` for \'production\' environment, set this string with `rails credentials:edit` (ArgumentError)         


        

Answer 1

I experienced this same issue when working on a Rails 5.2 application in production.

I already had other things set up. The problem for me was not that the secret_key_base wasn't set properly, it was rather because of the Passing the environment's name as a regular argument like below is deprecated

rails c RAILS_ENV=production

If you look at your error log generated closely from its top you will see this:

DEPRECATION WARNING: Passing the environment's name as a regular argument is deprecated and will be removed in the next Rails version. Please, use the -e option instead. (called from at bin/rails:9)

To run the rails console in a different environment, use the -e option like this:

rails console -e production

Note: Setting the secret_key_base in the secrets.yml file is not safe, as it's not a secure way of storing the key, please use the encrypted credential.yml file and the master key to decrypt it.

That's all.

I hope this helps
