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 ran into this problem when deploying my rails app to dokku using a Dockerfile. My solution:

the file config/secrets.yml references an environment variable:

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

I need to set this variable using the dokku command line (either directly on the server, or using the dokku-cli gem on my development machine):

dokku config:set SECRET_KEY_BASE=blalbalblablahblablah
