# Supported tags and respective `Dockerfile` links - [`latest`, `0.3.1` (*Dockerfile*)](https://github.com/dotcloud/hipache/blob/0.3.1/Dockerfile) For more information about this image and its history, please see the [relevant manifest file (`library/hipache`)](https://github.com/docker-library/official-images/blob/master/library/hipache) in the [`docker-library/official-images` GitHub repo](https://github.com/docker-library/official-images). # What is Hipache? **Hipache** (pronounced `hɪ'pætʃɪ`) is a distributed proxy designed to route high volumes of http and websocket traffic to unusually large numbers of virtual hosts, in a highly dynamic topology where backends are added and removed several times per second. It is particularly well-suited for PaaS (platform-as-a-service) and other environments that are both business-critical and multi-tenant. Hipache was originally developed at [dotCloud](http://www.dotcloud.com), a popular platform-as-a-service, to replace its first-generation routing layer based on a heavily instrumented nginx deployment. It currently serves production traffic for tens of thousands of applications hosted on dotCloud. Hipache is based on the node-http-proxy library. # Supported Docker versions This image is officially supported on Docker version 1.8.1. Support for older versions (down to 1.0) is provided on a best-effort basis. # User Feedback ## Documentation Documentation for this image is stored in the [`hipache/` directory](https://github.com/docker-library/docs/tree/master/hipache) of the [`docker-library/docs` GitHub repo](https://github.com/docker-library/docs).
