Consul API Client
This package provides the api
package which provides programmatic access to the full Consul API.
The full documentation is available on Godoc.
Usage
Below is an example of using the Consul client. To run the example, you must first install Consul and Go.
To run the client API, create a new Go module.
go mod init consul-demo
Copy the example code into a file called main.go
in the directory where the module is defined.
As seen in the example, the Consul API is often imported with the alias capi
.
package main
import (
"fmt"
capi "github.com/hashicorp/consul/api"
)
func main() {
// Get a new client
client, err := capi.NewClient(capi.DefaultConfig())
if err != nil {
panic(err)
}
// Get a handle to the KV API
kv := client.KV()
// PUT a new KV pair
p := &capi.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)
}
Install the Consul API dependency with go mod tidy
.
In a separate terminal window, start a local Consul server.
consul agent -dev -node machine
Run the example.
go run .
You should get the following result printed to the terminal.
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
