Seems you aren't using the etcd registry in the services call.
micro --registry etcd services
Extra info
You can add etcd with a noop import and then run the service with "--registry etcd", this allows easy switching of dependencies.
package main
import (
"go-micro.dev/v4"
"go-micro.dev/v4/logger"
"helloworld/handler"
pb "helloworld/proto"
_ "github.com/go-micro/plugins/v4/registry/etcd"
)
func main() {
// Create service
srv := micro.NewService(
micro.Name("helloworld"),
)
// Register handler
pb.RegisterHelloworldHandler(srv.Server(), handler.New())
// Run service
if err := srv.Run(); err != nil {
logger.Fatal(err)
}
}
Then:
micro run . --registry etcd
Same as:
go run main.go --registry etcd
This also configureable via ENV variables:
$ go run main.go --help

Micro v4 is not compatible with go-micro

Micro v4 is not compatible with go-micro
how can i registry a service to the micro server? any docs about that?
from go-micro.
Go to micro.dev and read the docs there. Effectively import micro.dev/v4/service and use "micro run [repo]"

Micro v4 is not compatible with go-micro
so there is not a way to registry a service to the go-micro with Micro v4:
import "go-micro.dev/v4"
func main() {
etcdReg := etcd.NewRegistry(registry.Addrs(":2379"))
// Create service
srv := micro.NewService(
micro.Name("greeterService"),
micro.Address(":6666"),
micro.Registry(etcdReg),
)
}
if i want to registry a service to micro server, the only way is use the import "micro.dev/v4/service"
?
from go-micro.
That's correct they are now two separate projects
from go-micro.

what the different between these and which one i should use?
from go-micro.
One is a platform. The other is a framework. Use go-micro if you want to piece everything together yourself.
