## プロジェクトの歴史と使われ方
Kamal Proxy is a small HTTP proxy from Basecamp for coordinating zero-downtime deployments behind Kamal. It exists to handle health checks, traffic switching, draining, host-based routing, path-based routing, and TLS features without requiring application code to participate in the deployment handoff.
### プロジェクトの歴史
The repository was created on 2024-03-21. Its README describes the proxy as part of Kamal's deployment experience, but also as usable standalone or in other deployment tooling.
Kamal itself is Basecamp's container deployment tool, originally built for Rails apps but documented as usable for any Docker-containerized web app. Kamal Proxy became the dedicated routing piece in that ecosystem, replacing ad hoc proxy handoff logic with a small Go service and CLI.
### 採用の歴史
Adoption follows Kamal adoption: teams using Kamal for single-server or small-fleet Docker deployments need a predictable way to switch traffic after a new container passes health checks. Homebrew and Nix packaging make the proxy available outside Kamal's own install path for operators who manage tools through system package managers.
### 使われ方
The README documents `kamal-proxy run` for starting the proxy and `kamal-proxy deploy` for registering a target service. Deployments wait for a new target to become healthy, route new traffic there, and drain traffic from the old target before returning.
### パッケージ好きにとっての重要性
Kamal Proxy is package-interesting because it is a subcomponent split out of a deployment system but useful enough to package as its own executable. It also reflects the 2020s return of simpler self-hosting tools: SSH, Docker, one proxy, and explicit release handoff instead of a full orchestrator.
### タイムライン
- 2024: basecamp/kamal-proxy repository created.
- 2024: v0.1.0 and later tags appeared in the repository.
- 2026: Kamal release notes required kamal-proxy v0.9.2 for Kamal v2.11.0 deployments.
### Related projects
- Kamal is the parent deployment tool that uses Kamal Proxy for request switching.
- It sits in the same operational space as reverse proxies and load balancers used for blue-green or rolling web deployments, but with a narrower Kamal-oriented interface.
