Docker compose: Traefik and Docker registry - docker

Question

My PC is a Windows 10 PRO with Docker Desktop CE Version 2.0.0.3 (31259) (Engine 18.09.2).
I'm building a docker-compose.yml file which runs Traefik, Portainer, GitLab, Jenkins and Registry containers.
Traefik is configured with SSL (self-signed certificate).
I've achieved to run the containers in their domains:
Traefik: https://traefik.localhost
Portainer: https://portainer.localhost
Gitlab: https://gitlab.localhost
Jenkins: https://jenkins.localhost
Registry: https://registry.localhost
When I run these URLs in a browser it returns me certificate error but I access web clients without problems.
If I access the URL https://registry.localhost/v2/_catalog from the browser I can read: {"repositories":[]} This is good. I just started my Registry and it's empty.
I generated the self-signed certificate with:
"C:\Program Files\OpenSSL-Win64\bin\openssl.exe" req -x509 -nodes -days 365 -newkey rsa:2048 -keyout traefik.key -out traefik.crt
I attach the configuration files. I omit part of the docker-compose.yml for short.
docker-compose.yml

services:
traefik:

volumes:
- /var/run/docker.sock:/var/run/docker.sock
- D:\docker-vols\paas\traefik\traefik.toml:/traefik.toml
- D:\docker-vols\paas\traefik\certs:/certs/

[entryPoints]
[entryPoints.http]

[entryPoints.http.redirect]
entryPoint = "https"
[entryPoints.https]

[entryPoints.https.tls]

keyFile = "/certs/traefik.key"
[api]
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "docker.localhost"
watch = true
exposedbydefault = false
I run it: docker-compose up
My problem comes when I want to push an image to my Registry from the host (my Windows PC) to test that it works perfectly. I follow the next steps:
docker pull hello-world
docker tag hello-world registry.localhost/my-hello-world
docker push registry.localhost/my-hello-world
Then it returns
The push refers to repository [registry.localhost/my-hello-world]
Get https://registry.localhost/v2/: dial tcp: lookup registry.localhost on 192.168.65.1:53: no such host
Where's my mistake? Thank you.
SOLUTION:
I forgot to add to /etc/hosts:
127.0.0.1 registry.localhost
