etcdsync is a distributed lock library in Go using etcd. It easy to use like sync.Mutex.
In fact, there are many similar implementation which are all obsolete
depending on library github.com/coreos/go-etcd/etcd which is official marked deprecated,
and the usage is a little bit complicated.
Otherwise this library is very very simple. The usage is simple, the code is simple.
go get -u github.com/zieckey/etcdsync
Steps:
- m, err := etcdsync.New()
- m.Lock()
- Do your business here
- m.Unlock()
package main
import (
"log"
"os"
"github.com/zieckey/etcdsync"
)
func main() {
m, err := etcdsync.New("/mylock", 10, []string{"http://127.0.0.1:2379"})
if m == nil || err != nil {
log.Printf("etcdsync.New failed")
return
}
err = m.Lock()
if err != nil {
log.Printf("etcdsync.Lock failed")
} else {
log.Printf("etcdsync.Lock OK")
}
log.Printf("Get the lock. Do something here.")
err = m.Unlock()
if err != nil {
log.Printf("etcdsync.Unlock failed")
} else {
log.Printf("etcdsync.Unlock OK")
}
}etcd2 or etcd3 test OK.
You need a etcd instance running on http://localhost:2379, then:
