Credman

Handy console tool for developers to manage Rails credentials.

Motivation

Rails credentials is a nice tool to store encrypted credentials directly in your repo. Starting with Rails 6.0 it brings multi environment credentials feature that allows us to split credentials into separate files.

But it also brought a lot of pain for developers:

  • Each enviroment credentials file must have a complete list of all keys. It's easy to forget to add a key into one of the environments (see set and delete command)
  • You have to manually open each environment file. It's ok for one file but not for 3 or more. It also brings mistakes you might miss until deploy to production. (see set and delete command)
  • Merge conflicts become a hell since files are encrypted (see conflicts command)
  • You can't easily see what keys were added/changed/deleted in the current branch (see diff command)

This gem is designed to solve all these problems and make life easier for developers who use multi environment credentials.

	google.recaptcha.secret:	nil
	circle_ci.token:	<secret>
test:

production:
	google.recaptcha.secret:	<secret>
	circle_ci.token:	<secret>

credman set

Add/change a value for a particular key. -e attribute is mandatory for this command.

bundle exec credman set new_service.super_key new_secret_value -e development,test,production
Output
development:
	new_service.super_key:	ADDED: new_secret_value
test:
	new_service.super_key:	ADDED: new_secret_value
production:
	new_service.super_key:	ADDED: new_secret_value

credman delete

Delete for keys. -e attribute is mandatory for this command.

bundle exec credman delete new_service.super_key new_service.another_key -e development,test,production
Output
development:
	new_service.super_key:	✅ deleted
	new_service.another_key:	❌ key not found, can't delete
test:
	new_service.super_key:	✅ deleted
	new_service.another_key:	❌ key not found, can't delete
production:
	new_service.super_key:	✅ deleted
	new_service.another_key:	❌ key not found, can't delete

credman diff

Shows all keys changed compared with main branch by default. You can set the default branch by adding config/credman.yml file with default_diff_branch: your_branch You can specify any branch from origin you want to. For example credman diff my_branch

bundle exec credman diff
Output
development:
	new_service.super_key:	 ADDED: "new_secret_value"
test:
	new_service.super_key:	 ADDED: "new_secret_value"
production:
	new_service.super_key:	 ADDED: "new_secret_value"

credman conflicts

Run it if you have merge conflicts in configs/credentials/*.yml.enc. That interactive tool will help you resolve the conflict. In most of cases it will just automagically resolve the conflicts. In case of a key was changed in both branches it will ask you to choose the correct value.

bundle exec credman conflicts
Output
development:
        ❗️ The key another_key changed in both branches, their: "another_value", our: "conflicting_value"
Which one should we use? Please type `their` or `our` to apply particular change or enter to abort.
> their
✅ another_key set as "another_value"
✅ Merged config for rspec has been saved
          resolves conflict with user input

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
