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.

Developing Consul
If you wish to work on Consul itself, you'll first need Go
installed (version 1.6+ is required). Make sure you have Go properly installed,
including setting up your 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 1.6+ 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 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.

with MinGW.
