When the metadata server is scanning the agents for potential servers it is parsing the version number which the agent provided when it joined. This version number has to conform to a certain format, i.e. 'n.n.n'. Without this version number properly set some tests fail with error messages that disguise the root cause. The default version number is currently set to 'unknown' in version/version.go which does not parse and triggers the tests to fail. The work around is to use a build tag 'consul' which will use the version number set in version_base.go instead which has the correct format and is set to the current release version. In addition, some parts of the code also require the version number to be of a certain value. Setting it to '0.0.0' for example makes some tests pass and others fail since they don't pass the semantic check. When using go build/install/test one has to remember to use '-tags consul' or tests will fail with non-obvious error messages. Using build tags makes the build process more complex and error prone since it prevents the use of the plain go toolchain and - at least in its current form - introduces subtle build and test issues. We should try to eliminate build tags for anything else but platform specific code. This patch removes all references to specific version numbers in the code and tests and sets the default version to '9.9.9' which is syntactically correct and passes the semantic check. This solves the issue of running go build/install/test without tags for the OSS build. |

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.
