Berglas is a tool for managing secrets on Google Cloud Platform (GCP). We've recommended secrets as a service as a technique to store and share secrets in modern distributed architectures in the past, and GCP offers Secret Manager for that purpose, and Berglas works well with Secret Manager. This is especially useful for those GCP services that don't have direct integration with Secret Manager yet; the alternative in such cases would be to write custom code or scripts. Berglas ships as a command-line tool and as a library, and both also come in handy in use cases beyond secrets as a service. The author of Berglas, who also happens to be the original author of HashiCorp Vault, now works at Google; however, Berglass is not an official Google product.
