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 } } */ package client
