# Supported tags and respective `Dockerfile` links - [`0.4.0`, `0.4`, `0`, `latest` (*Dockerfile*)](https://github.com/RocketChat/Docker.Official.Image/blob/607714350ff360aa5e0e493fd2cb6057684a980b/Dockerfile) For more information about this image and its history, please see the [relevant manifest file (`library/rocket.chat`)](https://github.com/docker-library/official-images/blob/master/library/rocket.chat) in the [`docker-library/official-images` GitHub repo](https://github.com/docker-library/official-images). # Rocket.Chat Rocket.Chat is a Web Chat Server, developed in JavaScript, using the Meteor fullstack framework. It is a great solution for communities and companies wanting to privately host their own chat service or for developers looking forward to build and evolve their own chat platforms. ![logo](https://rawgit.com/docker-library/docs/master/rocket.chat/logo.svg) # How to use this image First, start an instance of mongo: docker run --name db -d mongo --smallfiles Then start Rocket.Chat linked to this mongo instance: docker run --name rocketchat --link db -d rocket.chat This will start a Rocket.Chat instance listening on the default Meteor port of 3000 on the container. If you'd like to be able to access the instance directly at standard port on the host machine: docker run --name rocketchat -p 80:3000 --env ROOT_URL=http://localhost --link db -d rocket.chat Then, access it via `http://localhost` in a browser. Replace `localhost` in `ROOT_URL` with your own domain name if you are hosting at your own domain. If you're using a third party Mongo provider, or working with Kubernetes, you need to override the `MONGO_URL` environment variable: docker run --name rocketchat -p 80:3000 --env ROOT_URL=http://localhost --env MONGO_URL=mongodb://mymongourl/mydb -d rocket.chat # License View [license information](https://github.com/RocketChat/Rocket.Chat/blob/master/LICENSE) for the software contained in this image. # Supported Docker versions This image is officially supported on Docker version 1.8.1.
