# Muguet
[](https://travis-ci.org/mattallty/muguet) [](https://coveralls.io/github/mattallty/muguet?branch=master)
> *Muguet* is a DNS Server & Reverse proxy for Docker environments.
> Compatible with [docker-compose](https://docs.docker.com/compose/), [boot2docker](http://boot2docker.io/) and [docker-machine](https://docs.docker.com/machine/)
## Introduction
When using Docker, it's sometimes a pain to access your containers using specific IPs/ports.
*Muguet* provides you with a [DNS Server](https://en.wikipedia.org/wiki/Domain_Name_System)
that resolves auto-generated hostnames to your containers IPs,
plus a [Reverse Proxy](https://en.wikipedia.org/wiki/Reverse_proxy) to access all your web apps on port 80.
## Prerequisites
- A running [Docker](https://www.docker.com/) environment
- [Node.js](https://nodejs.org/) or [io.js](https://iojs.org)
## Install
- **Install Muguet**
```bash
npm install -g muguet
```
- **Start Muguet (as root)**
```bash
sudo muguet up
```
## Usage
```bash
sudo muguet up [options]
# or
sudo -E bash -c 'muguet up [options]'
```
Notes:
- *Muguet* **must** be run as *root* to be able to bind port 80
- *Muguet* needs to read *DOCKER_HOST* and *DOCKER_CERT_PATH* environment variables. If these variables are not available, *Muguet*
will try to guess it from `docker-machine` or `boot2docker` (if detected).
- If the previous method fails, please consider running *Muguet* like `sudo -E bash -c 'muguet up'` as it makes all needed environment
variables (eg. from your normal user env) available to the *muguet* command (eg. to the root user).
## Generated hostnames
For each container, *Muguet* generates several DNS entries:
- `container_id`.docker
- `hostname`.docker (when running a container with -h option)
- `compose-service`.docker (if using Docker Compose)
- And possibly others based on the `org.muguet.dns.subdomain-map` label (see below)
## Labels
Docker `labels` are used as configuration settings.
#### org.muguet.reverse-proxy.enabled
Set it to `1` to enable the reverse-proxy (only enable reverse-proxy for web apps).
#### org.muguet.reverse-proxy.only-ports
A comma-separated list of ports that you want to *proxify*.
#### org.muguet.dns.subdomain-map
A comma-separated list of `subdomain:port` to map.
## Example
```yml
# site1 will be accessible on http://site1.docker
site1:
build: ./build/docker/site1
ports:
- "8081"
labels:
# We enable the reverse-proxy so the app will be available on port 80 rather than 8081
- "org.muguet.reverse-proxy.enabled=1"
# site2 will be accessible on http://site2.docker and on http://back-office.docker
site2:
build: ./build/docker/site2
hostname: back-office
ports:
- "8082"
labels:
# We enable the reverse-proxy so the app will be available on port 80 rather than 8082
- "org.muguet.reverse-proxy.enabled=1"
# More complex
# despite not recommended, this container expose several services (mysql, apache, node.js)
# So we have to setup a subdomain-map so each service will be given a distinct hostname
bigcontainer:
image: big/big-container
ports:
- "3306"
- "80"
- "8990"
labels:
# Enable reverse-proxy
- "org.muguet.reverse-proxy.enabled=1"
# Reverse-proxy only web apps, but NOT MySQL
- "org.muguet.reverse-proxy.only-ports=80,8990"
# Will bind:
# apache.bigcontainer.docker
# nodejs.bigcontainer.docker
# mysql.bigcontainer.docker
- "org.muguet.dns.subdomain-map=apache:80,nodejs:8990,mysql:3306"
```
## Dashboard & REST API
A dashboard and a REST API are available on port `9876` (customizable with `--api-port`) and proxified on port 80.
A default domain `muguet.docker` (or `muguet.{domain}`) is generated so you can access it
through [http://muguet.docker](http://muguet.docker)
