Generate stable random name from string (used to generate docker tag from git branch)

main.go

package main

import (
	"fmt"
	"hash/fnv"
	"math/rand"
	"os"

	"github.com/docker/docker/pkg/namesgenerator"
)

func hash(s string) uint64 {
	alg := fnv.New64a()
	alg.Write([]byte(s))
	return alg.Sum64()
}

func main() {
	branch := os.Args[1]
	seed := int64(hash(branch))
	rand.Seed(seed)
	fmt.Println(namesgenerator.GetRandomName(0))
}
