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, FreeBSD, Solaris, and Windows.

## Quick Start
|
|
|
|
An extensive 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 1.9+ 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:
|
|
|
|
```
|
|
$ make
|
|
...
|
|
$ bin/consul
|
|
...
|
|
```
|
|
|
|
*Note: `make` will build all os/architecture combinations. Set the environment variable `CONSUL_DEV=1` to build it just for your local machine's os/architecture, or use `make dev`.*
|
|
|
|
*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`. The test suite may fail if
|
|
over-parallelized, so if you are seeing stochastic failures try
|
|
`GOTEST_FLAGS="-p 2 -parallel 2" make test`.
|
|
|
|
If you make any changes to the code, run `make format` in order to automatically
|
|
format the code according to Go standards.
|
|
|
|
## Vendoring
|
|
|
|
Consul currently uses [govendor](https://github.com/kardianos/govendor) for
|
|
vendoring and [vendorfmt](https://github.com/magiconair/vendorfmt) for formatting
|
|
`vendor.json` to a more merge-friendly "one line per package" format.
