使用go初步调用etcd

使用go初步調用etcd

package main

import (
    "context"
    "go.etcd.io/etcd/clientv3"
    "time"
)

func main() {
    config := clientv3.Config{
        Endpoints:   []string{"106.12.72.181:23791", "106.12.72.181:23792"},
        DialTimeout: 10 * time.Second,
    }
    client, _ := clientv3.New(config)
    defer client.Close()
    kv := clientv3.NewKV(client)
    ctx := context.Background() //需要放入一个context，看自己需求选择合适的ctx
    kv.Put(ctx,"/services/user","user1") //插入一条数据
}

可以看到etcd集群中两个节点都可以查询到这个key

root@instance-emh5jlpa:~# docker exec -it etcd1 sh
/go # etcdctl get /services/user
/services/user
user1
/go # exit
root@instance-emh5jlpa:~# docker exec -it etcd2 sh
/go # etcdctl get /services/user
/services/user
user1
