“Many applications require credentials to connect to a database, API keys to invoke a service, or certificates for authentication,” Google developer advocate Seth Vargo and product manager Matt Driscoll wrote in today’s announcement. “Managing and securing access to these secrets is often complicated by secret sprawl, poor visibility, or lack of integrations.”
With Berglas, Google already offered an open-source command-line tool for managing secrets. Secret Manager and Berglas will play well together and users will be able to move their secrets from the open-source tool into Secret Manager and use Berglas to create and access secrets from the cloud-based tool as well.
With KMS, Google also offers a fully managed key management system (as do Google Cloud’s competitors). The two tools are very much complementary. As Google notes, KMS does not actually store the secrets — it encrypts the secrets you store elsewhere. Secret Manager provides a way to easily store (and manage) these secrets in Google Cloud.
Secret Manager includes the necessary tools for managing secret versions and audit logging, for example. Secrets in Secret Manager are also project-based global resources, the company stresses, while competing tools often manage secrets on a regional basis.
The new tool is now in beta and available to all Google Cloud customers.
