go-etcd-lock

A simple lock library on top of etcd in Go.

Locks are acquired with a timeout which will be automatically refreshed so long as the node with the lock remains alive. If a node holding a lock were to die, the lock would automatically release after the timeout period, and a new node would be granted the lock.

Example

import "github.com/hayesgm/go-etcd-lock/lock"

goChan, stopChan := lock.Acquire(cli, "mylock", 20) // Try to get a lock with 20 second timeout

go func() {
  <- goChan // Wait to Acquire lock
  
  for run := true; run; {
    select {
    case <-stopChan:
      run = false // We're going to exit
    default:
      log.Println("I am king")
    }
  }
}
