Package client provides bindings for the etcd APIs.
Create a Config and exchange it for a Client:
import (
"net/http"
"github.com/coreos/etcd/client"
"golang.org/x/net/context"
)
cfg := client.Config{
Endpoints: []string{"http://127.0.0.1:2379"},
Transport: DefaultTransport,
}
c, err := client.New(cfg)
if err != nil {
// handle error
}
Create a KeysAPI using the Client, then use it to interact with etcd:
kAPI := client.NewKeysAPI(c)
// create a new key /foo with the value "bar"
_, err = kAPI.Create(context.Background(), "/foo", "bar")
if err != nil {
// handle error
}
// delete the newly created key only if the value is still "bar"
_, err = kAPI.Delete(context.Background(), "/foo", &DeleteOptions{PrevValue: "bar"})
if err != nil {
// handle error
}
Use a custom context to set timeouts on your operations:
import "time"
ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
defer cancel()
// set a new key, ignoring it's previous state
_, err := kAPI.Set(ctx, "/ping", "pong", nil)
if err != nil {
if err == context.DeadlineExceeded {
// request took longer than 5s
} else {
// handle error
}
}
