Hi Sulhan, Anderson,
Thanks for your guidance. It works now using time.Ticker
func worker() {
tiker := time.NewTicker(30 * time.Second)
for _ = range tiker.C {
mu.Lock()
for keyid := range idtime {
d := time.Now().Unix() - idtime[keyid]
if d >= 60 {
// delete resouce in database after 60 seconds
_ = DeleteNFInstance(ctx, keyid)
}
}
mu.Unlock()
}
}
