Project history and usage
Chamber is Segment's CLI for managing secrets in AWS Systems Manager Parameter Store. It stores values under service/key paths and can inject them into process environments for application startup.
Project history
The public repository was created in June 2017 and v1.0.0 was released two days later. The README frames Chamber as a tool for managing secrets through SSM Parameter Store and documents AWS IAM and KMS requirements.
The README records important compatibility milestones: version 2.0 moved to Parameter Store's path-based API by default, and version 3.0 reserved the _chamber service name for internal use.
Adoption history
Chamber is packaged by Homebrew and Nix according to the input package facts, while upstream GitHub releases provide the main release channel. The README also recommends use with aws-vault, showing how it fits into AWS operator workflows.
How it is used
Common commands write, read, list, tag, export, import, and show history for secrets. The exec command loads secrets from one or more services, converts secret keys to environment variable names, and runs a child process with those values.
Why package nerds care
Chamber is significant because it made AWS SSM Parameter Store usable as a lightweight secrets backend from a single Go CLI. For package managers, it is the kind of small operational binary that replaced custom shell glue around AWS APIs.
