Hi. We successfully store secrets in ansible variables files with either ansible-vault or sops. It is a good approach when Ansible itself configures something that requires a secret, such as configuring a database admin password.

But I’d like to ask you about how you store secrets meant to be used by applications. Example: we have a an application in PHP with a config.php file with all credentials needed by the application. Developers have a config.php setup to work with the test environment, while we maintain a different config.php for production in production machines. Nowadays this config.php file is stored in ansible repository, encrypted by ansible-vault or sops. We thought about moving the config.php production file to the application repository, so we could get advantage of the CI/CD pipeline.

It doesn’t smell right, because it would require to encrypt it somehow, and store keys to decrypt it in CI/CD, but I decided to ask you anyway what do you think of that and how you solved it yourselves.

Thanks!
