Namely, don't check the DNS names in TLS certificates when connecting to other servers. As of golang 1.3, crypto/tls no longer natively supports doing partial verification (verifying the cert issuer but not the hostname), so we have to disable verification entirely and then do the issuer verification ourselves. Fortunately, crypto/x509 makes this relatively straightforward. If the "server_name" configuration option is passed, we preserve the existing behavior of checking that server name everywhere. No option is provided to retain the current behavior of checking the remote certificate against the local node name, since that behavior seems clearly buggy and unintentional, and I have difficulty imagining it is actually being used anywhere. It would be relatively straightforward to restore if desired, however. |

Consul
- Website: http://www.consul.io

on Freenode - 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, 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:

Developing Consul
If you wish to work on Consul itself, you'll first need Go installed (version 1.2+ 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 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.
