# Consul [![Build Status](https://travis-ci.org/hashicorp/consul.png)](https://travis-ci.org/hashicorp/consul)

Consul is a tool for service discovery and configuration. Consul is
distributed, highly available, and extremely scalable.
Consul provides several key features:
* **Service Discovery** - Consul makes it simple for services to register
themselves and to discover other services via a DNS or HTTP interface.
External services such as SaaS providers can be registered as well.
* **Health Checking** - Health Checking enables Consul to quickly alert
operators about any issues in a cluster. The integration with service
discovery prevents routing traffic to unhealthy hosts and enables service
level circuit breakers.
* **Key/Value Storage** - A flexible key/value store enables storing
dynamic configuration, feature flagging, coordination, leader election and
more. The simple HTTP API makes it easy to use anywhere.
* **Multi-Datacenter** - Consul is built to be datacenter aware, and can
support any number of regions without complex configuration.
Consul runs on Linux, Mac OS X, and Windows. It is recommended to run the
Consul servers only on Linux, however.
## Quick Start
An extensive quick quick start is viewable on the Consul website:

## Documentation
Full, comprehensive documentation is viewable on the Consul website:

## Developing Consul
If you wish to work on Consul itself, you'll first need [Go](https://golang.org)
installed (version 1.5.1+ is _required_). Make sure you have Go properly installed,
including setting up your [GOPATH](https://golang.org/doc/code.html#GOPATH).
Next, clone this repository into `$GOPATH/src/github.com/hashicorp/consul` and
then just type `make`. In a few moments, you'll have a working `consul` executable:
```
$ go get -u ./...
$ make
...
$ bin/consul
...
```
*note: `make` will also place a copy of the binary in the first part of your $GOPATH*
You can run tests by typing `make test`.
If you make any changes to the code, run `make format` in order to automatically
format the code according to Go standards.
### Building Consul on Windows
Make sure Go 1.5.1+ is installed on your system and that the Go command is in your
%PATH%.
For building Consul on Windows, you also need to have MinGW installed.
[TDM-GCC](http://tdm-gcc.tdragon.net/) is a simple bundle installer which has all
the required tools for building Consul with MinGW.
Install TDM-GCC and make sure it has been added to your %PATH%.
If all goes well, you should be able to build Consul by running `make.bat` from a
command prompt.

for more information of how to set up a general Go build environment on Windows
with MinGW.
