## プロジェクトの歴史と使われ方

Berglas is a GoogleCloudPlatform command-line tool and Go library for storing and retrieving secrets on Google Cloud. It predates some common Secret Manager workflows and bridges Cloud KMS, Cloud Storage, and Secret Manager access patterns.

### プロジェクトの歴史

The Berglas repository was created in April 2019, with a v0.1.3 release published in June 2019. Its README describes it as both a CLI for encrypting, decrypting, and storing data on Google Cloud and a library for injecting secrets into Google Cloud runtimes.

The project is explicit about its support status: it lives under GoogleCloudPlatform but is not an officially supported Google product.

### 採用の歴史

Berglas adoption came from teams that needed secret handling around Cloud KMS and Cloud Storage, then later interoperability with Secret Manager. It fit CI/CD and serverless workflows where environment injection and CLI automation were convenient.

Homebrew packaging made it easy for macOS operators to bootstrap and inspect Google Cloud secret workflows locally while using Application Default Credentials from the Cloud SDK.

### 使われ方

Common commands create secrets, grant access, read secret data, bootstrap buckets and KMS keys, and run child processes with secrets populated in the environment.

Authentication usually follows Google Cloud Application Default Credentials, which is why the package curation points at the gcloud ADC credentials file rather than a Berglas-specific credentials file.

### パッケージ好きにとっての重要性

Berglas is package-nerd significant as a small Go security CLI with cloud-side state. Installing the package gives a local executable, but most real behavior depends on enabled Google Cloud services, IAM, KMS keys, buckets, or Secret Manager resources.

It is also a snapshot of a transitional Google Cloud secrets era: the tool supports the older Cloud Storage plus KMS pattern while documenting interoperability with Secret Manager.

### タイムライン

- 2019-04: The GoogleCloudPlatform/berglas repository was created.
- 2019-06: Berglas v0.1.3 was published.
- 2020s: Berglas documentation continued to emphasize Cloud KMS, Cloud Storage, Secret Manager interoperability, and ADC-based setup.

### Related projects

- Google Cloud KMS supplies encryption keys for the original storage model.
- Google Cloud Storage stores encrypted secret blobs in the original model.
- Google Secret Manager is the related managed service with Berglas interoperability.
