* agent: add option to discard health output In high volatile environments consul will have checks with "noisy" output which changes every time even though the status does not change. Since the output is stored in the raft log every health check update unblocks a blocking call on health checks since the raft index has changed even though the status of the health checks may not have changed at all. By discarding the output of the health checks the users can choose a different tradeoff. Less visibility on why a check failed in exchange for a reduced change rate on the raft log. * agent: discard output also when adding a check * agent: add test for discard check output * agent: update docs * go vet * Adds discard_check_output to reloadable config table. * Updates the change log. |

Consul
- Website: https://www.consul.io
- Chat: Gitter
- Mailing list: Google Groups
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 installed (version 1.9+ 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:
$ 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
.
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 for vendoring.
