Consul API client
=================
This package provides the `api` package which attempts to
provide programmatic access to the full Consul API.
Currently, all of the Consul APIs included in version 0.6.0 are supported.
Documentation
=============
The full documentation is available on [Godoc](https://godoc.org/github.com/hashicorp/consul/api)
Usage
=====
Below is an example of using the Consul client:
```go
package main
import "github.com/hashicorp/consul/api"
import "fmt"
func main() {
// Get a new client
client, err := api.NewClient(api.DefaultConfig())
if err != nil {
panic(err)
}
// Get a handle to the KV API
kv := client.KV()
// PUT a new KV pair
p := &api.KVPair{Key: "REDIS_MAXCLIENTS", Value: []byte("1000")}
_, err = kv.Put(p, nil)
if err != nil {
panic(err)
}
// Lookup the pair
pair, _, err := kv.Get("REDIS_MAXCLIENTS", nil)
if err != nil {
panic(err)
}
fmt.Printf("KV: %v %s\n", pair.Key, pair.Value)
}
```
To run this example, start a Consul server:
```bash
consul agent -dev
```
Copy the code above into a file such as `main.go`.
Install and run. You'll see a key (`REDIS_MAXCLIENTS`) and value (`1000`) printed.
```bash
$ go get
$ go run main.go
KV: REDIS_MAXCLIENTS 1000
```
After running the code, you can also view the values in the Consul UI on your local machine at http://localhost:8500/ui/dc1/kv

Consul Testing Utilities
========================
This package provides some generic helpers to facilitate testing in Consul.
TestServer
==========
TestServer is a harness for managing Consul agents and initializing them with
test data. Using it, you can form test clusters, create services, add health
checks, manipulate the K/V store, etc. This test harness is completely decoupled
from Consul's core and API client, meaning it can be easily imported and used in
external unit tests for various applications. It works by invoking the Consul
CLI, which means it is a requirement to have Consul installed in the `$PATH`.
Following is an example usage:
```go
package my_program
import (
"testing"
"github.com/hashicorp/consul/consul/structs"
"github.com/hashicorp/consul/sdk/testutil"
)
func TestFoo_bar(t *testing.T) {
// Create a test Consul server
srv1, err := testutil.NewTestServerConfigT(t, nil)
if err != nil {
t.Fatal(err)
}
defer srv1.Stop()
// Create a secondary server, passing in configuration
// to avoid bootstrapping as we are forming a cluster.
srv2, err := testutil.NewTestServerConfigT(t, func(c *testutil.TestServerConfig) {
c.Bootstrap = false
})
if err != nil {
t.Fatal(err)
}
defer srv2.Stop()
// Join the servers together
srv1.JoinLAN(t, srv2.LANAddr)
// Create a test key/value pair
srv1.SetKV(t, "foo", []byte("bar"))
// Create lots of test key/value pairs
srv1.PopulateKV(t, map[string][]byte{
"bar": []byte("123"),
"baz": []byte("456"),
})
// Create a service
srv1.AddService(t, "redis", structs.HealthPassing, []string{"master"})
// Create a service that will be accessed in target source code
srv1.AddAccessibleService("redis", structs.HealthPassing, "127.0.0.1", 6379, []string{"master"})
// Create a service check
srv1.AddCheck(t, "service:redis", "redis", structs.HealthPassing)
// Create a node check
srv1.AddCheck(t, "mem", "", structs.HealthCritical)
// The HTTPAddr field contains the address of the Consul
// API on the new test server instance.
println(srv1.HTTPAddr)
// All functions also have a wrapper method to limit the passing of "t"
wrap := srv1.Wrap(t)
wrap.SetKV("foo", []byte("bar"))
}
```
