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. ### Timeline - 2017: GitHub repository created. - 2017: v1.0.0 published on GitHub releases. - 2018: README documents version 2.0 path-based Parameter Store behavior. - 2025: v3.1.x releases continue maintenance. - 2026: v3.1.5 published on GitHub releases. ### Related projects - AWS SSM Parameter Store is the storage backend Chamber manages. - AWS KMS is used for encryption key configuration in the documented workflow. - aws-vault is recommended by the README as one way to provide AWS credentials safely. ### Sources - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** chamber - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - chamber: normalized package name match | nixpkgs package indexes: pkgs/by-name/ch/chamber/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Cloud CLI packages](https://www.automicvault.com/pkg/cloud-clis/) - Belongs to a cloud or infrastructure command family. - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [infisical](https://www.automicvault.com/pkg/brew/infisical/) - Shares av.db curated category or tags: cli, devops, secrets-management, security. - [credstash](https://www.automicvault.com/pkg/brew/credstash/) - Shares av.db curated category or tags: cli, secrets-management, security. - [doppler](https://www.automicvault.com/pkg/brew/doppler/) - Shares av.db curated category or tags: cli, devops, secrets-management, security. - [openbao](https://www.automicvault.com/pkg/brew/openbao/) - Shares av.db curated category or tags: cli, secrets-management, security. - [secretspec](https://www.automicvault.com/pkg/brew/secretspec/) - Shares av.db curated category or tags: cli, secrets-management, security. - [sops](https://www.automicvault.com/pkg/brew/sops/) - Shares av.db curated category or tags: cli, secrets-management, security. - [varlock](https://www.automicvault.com/pkg/brew/varlock/) - Shares av.db curated category or tags: cli, secrets-management, security. - [vaulted](https://www.automicvault.com/pkg/brew/vaulted/) - Shares av.db curated category or tags: cli, go, secrets-management, security. - [shush](https://www.automicvault.com/pkg/brew/shush/) - Security-sensitive metadata or terminology overlaps.
