etcdfs: virtual file system on etcd

Install

1. go get github.com/chai2010/etcdfs

Example

Start etcd in local:

etcd

Put some data to edcd:

ETCDCTL_API=3 etcdctl put /abc/readme.md abc/aaa-value
ETCDCTL_API=3 etcdctl put /abc/hello.go  "package main; func main(){}"
ETCDCTL_API=3 etcdctl get --prefix ""

Create go progrom:

package main

import (
	"flag"
	"log"
	"net/http"
	"strings"
	"time"

	"golang.org/x/tools/godoc/vfs"
	"golang.org/x/tools/godoc/vfs/httpfs"

	"github.com/chai2010/etcdfs"
)

var (
	flagEtcdHost = flag.String("ectd-host", "localhost:2379", "set etcd nodes")
)

func main() {
	flag.Parse()

	etcdClient, err := etcdfs.NewEtcdClient(strings.Split(*flagEtcdHost, ","), time.Second/10)
	if err != nil {
		log.Fatal(err)
	}

	ns := vfs.NameSpace{}
	ns.Bind("/", etcdfs.New(etcdClient), "/", vfs.BindReplace)

	http.Handle("/", http.FileServer(httpfs.New(ns)))

	log.Fatal(http.ListenAndServe(":8080", nil))
}

Run the program (hello.go):

go run hello.go

Then open http://127.0.0.1:8080/ in browser.
