Package client provides bindings for the etcd APIs.
|
|
|
|
Create a Config and exchange it for a Client:
|
|
|
|
import (
|
|
"net/http"
|
|
"context"
|
|
|
|
"go.etcd.io/etcd/client/v2"
|
|
)
|
|
|
|
cfg := client.Config{
|
|
Endpoints: []string{"http://127.0.0.1:2379"},
|
|
Transport: DefaultTransport,
|
|
}
|
|
|
|
c, err := client.New(cfg)
|
|
if err != nil {
|
|
// handle error
|
|
}
|
|
|
|
Clients are safe for concurrent use by multiple goroutines.
|
|
|
|
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 its previous state
|
|
_, err := kAPI.Set(ctx, "/ping", "pong", nil)
|
|
if err != nil {
|
|
if err == context.DeadlineExceeded {
|
|
// request took longer than 5s
|
|
} else {
|
|
// handle error
|
|
}
|
|
}
|
|
|
