Does `config.requre_master_key = false` in production cause any problem?

My application is created by Rails 5.2.2, and it requires master.key when I build assets even though it doesn't use actually. I provide my application as docker image, so I need to build it while creating the image, but I don't want to include my master.key in it. I also know actually needed is secret_key_base, so I tried to expose dummy SECRET_KEY_BASE as environment variable, but bundle exec rails assets:precompile RAILS_ENV=production is failed because there is config.require_master_key = true in my config file. I think if this settings turn to false, the application doesn't check whether master.key exists or not, and it will work fine. But I don't know why default value is true, so I can't decide to do it.
Does config.requre_master_key = false cause any problem? Can anyone help me?
