* Copy-and-paste Go client example Includes Go source that runs without modification, as well as simple instructions for compiling, running, and viewing the output in the Consul UI. * Remove unnecessary flags from development server example This is a bare minimum Go example needed to store keys and values in Consul. The `-ui` and `-server` flags aren't needed when running with `-dev`.

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
Usage
Below is an example of using the Consul client:
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:
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.
$ 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
