How to query Go-micro services(v2) inside docker with curl or postman - docker-compose

Question

I use Go-micro(v2) to deploy services inside docker-compose
user-service:
build:
context: ./user-service
restart: always
ports:
- "8086:8086"
deploy:
mode: replicated
replicas: 1
environment:....
See the service configuration
srv = micro.NewService(
micro.Name("my.user"),
micro.Address("127.0.0.1:8086"))
when running docker-compose, the container logs show
2022-07-31 05:43:53 file=v2#v2.9.1/service.go:200 level=info Starting [service] my.user
2022-07-31 05:43:53 file=grpc/grpc.go:864 level=info Server [grpc] Listening on [::]:8086
2022-07-31 05:43:53 file=grpc/grpc.go:697 level=info Registry [mdns] Registering node: my.user-00ee4795-06df-47f1-a07a-cc362e135864
All looks good.
But when I want to query some handlers using curl or postman(for development purpose), It doesn't work,
see an exemple of failed request with postman
GET http://127.0.0.1:8086/my.user/Get
Error: Parse Error: Expected HTTP/
Request Headers
Content-Type: application/json
User-Agent: PostmanRuntime/7.29.2
Accept: */*
Postman-Token: b5ab718a-341b-40ff-81fa-37c66fd4d9f2
Host: 127.0.0.1:8086
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Request Body
GET http://127.0.0.1:8086/my.user/userService/Get // same error
with curl it is not better
curl --header "Content-Type:application/json" --http0.9 --output GET http://localhost:8086/my.user/Get
% Total % Received % Xferd Average Speed Time Time Time Current

curl --header "Content-Type:application/json" --http0.9 --output GET http://localhost:8086/my.user/userService/Get

Any idea how to query locally some go-micro services ? Thank you.
ps: Note that the 'Get' handler is working
